Linux+WindowsNT mini-HOWTO <author>Miroslav Skoric, <tt/m.skoric@eunet.yu/ <date>v2.1, 01 August 2000 <abstract> <nidx>windows nt</nidx> This mini-HOWTO covers some ways on how to install both Linux and Windows NT on the same computer and how to boot either of them from within LILO menu. There is also another mini-HOWTO "Linux+NT-Loader" that covers how to boot either of them from within NT Loader menu. </abstract> <sect>INTRODUCTION Bill Wohler wrote in v1.1 of The Linux+WindowsNT mini-HOWTO: "Due to hardware or software problems or user headroom, I pulled my hair out for several days trying to get both NT and Linux happily settled on my new HP Vectra PC at work." I could say that was true in my case too, but you <bf/really/ have a way to make both Linux and Windows NT co-existing on the same machine and to switch from one of them to another. "Under no circumstances run the Disk Administrator from NT 3.51 to format partitions. It asks if it can write a signature "which will cause absolutely no harm." When it did this, it hosed my partition table until fixed by steps 3 and 7 below. Because of these problems, I was limited to one FAT NT partition. Also remember that even if you do get the Disk Administrator to work, you'll want at least one small FAT partition to use as a staging area for exchanging files between Linux and NT until Linux has an NTFS filesystem." Well, NT's Disk Administrator is sufficient tool to check what situation on your hard disk(s) you have, before and after you used an utility called Partition Magic by Power Quest. This utility might be needed to 'shrink' your NT (either NTFS or FAT) partition, in order to get some free space for your further Linux' partitions. "I installed Linux first and then NT, but based on my experience, I might now be able to install NT first and then Linux." Of course you all are able to install Windows NT first and after that Linux. We'll see how to do that and how to use <bf/LILO/ (<bf/Li/nux <bf/Lo/ader) to choose which operating system to boot. But, before that we'll see the procedure that the previous maintainer of this mini-HOWTO has been using: <sect>INSTALLATION <sect1>Linux first, NT after 1. Install a minimal Linux (hold off on installing the rest until you win the Linux/NT battle). Do all your disk partitioning in Linux, including your NT partition (make it FAT). I was not successful at making more than one NT partition. I also made it the first partition, but I don't know if that is essential or not. 2. Edit /etc/lilo.conf and use boot=/dev/sda (I was not successful at installing LILO on the Linux partition--/dev/sda3 in my case) and run "lilo". You'll have to use the editor ae. You'll live. 3. Save the MBR with this: dd if=/dev/sda of=/dev/fd0 bs=512 count=1 Use a floppy. Trust me. Also do this each time you change the disk partition table. 4. Install NT, part 1. When it goes to reboot halfway through the process you'll boot into Linux. 5. Add NT stanza to /etc/lilo.conf, e.g.: other=/dev/sda1 label=NT table=/dev/sda and run lilo. If lilo complains about this (I forget the message), add the "linear" flag to /etc/lilo.conf near the "compact" keyword. Furthermore, if your partition table is screwed up by NT you'll either need to use "ignore-table" or follow the directions in Step 7. See also "fix-table". The LILO HOWTO is your friend. 6. Reboot, select NT from LILO, and finish NT install. You'll need the "Boot Disk XU, HP Vectra AIC 7880 Driver A.01.02" floppy to install the ethernet drivers and the "XU/VT Drivers and Documentation" CD (directory video/disk4 if I recall correctly) to install the video drivers for the Matrox MGA Millennium. 7. Back to Linux, run fdisk and ensure you don't get "partition doesn't end on cylinder boundary" on your Linux partitions. You'll still have this error on the NT partition though, but this seems to be OK. /dev/sda1 1 1 322 329301 6 DOS 16-bit >=32M Partition 1 does not end on cylinder boundary: phys=(321, 39, 9) should be (321, 63, 32) Cfdisk reports strangeness, but it seems OK: Unusable 0.04* /dev/sda1 Primary DOS 16-bit >=32Mb 321.59* Unusable 0.39* If you do get the cylinder boundary warning on your Linux partitions, it is sufficient to use cfdisk to do something innocuous like changing the boot sector. If, however, NT has really screwed you over and cfdisk can't even run, complaining that it cannot open /dev/sda, then you'll need to take more extreme action. You'll need that MBR you saved previously. Clear and restore the MBR (but not the signature) with: dd if=/dev/zero of=/dev/sda bs=512 count=1 dd if=/dev/fd0 of=/dev/sda bs=510 count=1 8. Install the rest of Linux. Easy, huh? If you prefer to have NT write the MBR instead of LILO, you may have to resort to the following to clear the MBR first: <itemize> <item>dd if=/dev/zero of=/dev/sda bs=446 count=1 (in Linux) or perform a low-level format with the SCSI utilities. I've heard that a low-level format of an IDE disk is fatal, so don't do it. <item>fdisk /mbr (you've obviously already created a DOS boot disk that contains fdisk). <item>delete NT partition and create it again in NT install. <item>continue with NT install. </itemize> Epilogue: After first posting this message, I heard from several folks that they had no problems with NT's Disk Administrator, and were able to install either NT or Linux first without any problems. Hopefully, you'll be in this camp, but if not, perhaps this campfire story will be of some use. Since the first edition of this mini-HOWTO, others have written similar documents as well. Please be sure to consult them. If your experience differs from any presented, then you should submit your own mini-HOWTO or submit a revised version of this document to the HOWTO maintainer (reference this sentence) and send a carbon copy to me as I don't have the time to maintain this document. Someone should eventually combine all of these documents into a single coherent HOWTO. Finally, I'm afraid this document details all I know about this subject. I should point you to an appropriate Linux newsgroup for further information. I use NT about one day a year. Under duress. <sect1>NT first, Linux after <sect2>2.2.1 If you have only one IDE hard disk <itemize> <item>First of all, I would suggest you to install a fresh copy of Windows NT 4.0 on your hard disk. I suppose that you already made a backup of your important data, so the NT installation shouldn't be a problem. During the NT installation, setup is not going to ask you where to place NT's boot loader, so it would be placed into the MBR (Master Boot Record) of your hard disk. But, there is a possibility for a previous content of the MBR to remain within the MBR (especially any previous Lilo), so I would suggest you (before installation of NT) to boot the computer with a DOS floppy diskette having DOS version of FDISK. At the prompt a:\ just enter the command: fdisk /mbr and restart the computer again (without that floppy). <item>After you have successfully installed your NT, you will see that it uses the whole hard disk or a specific partition of the hard disk (depending on what you decided during the setup process). So, it is advisible to 'shrink' the partition where NT resides in order to make some free space on the disk. Onto that free space you will install your Linux. After you have your NT configured and running, you have to boot your computer using a floppy diskette with Partition Magic utility by Power Quest. It is a graphical tool able to see all partitions on all hard disks you have. The best thing is that you can make some changes with your partitions but not to destroy your existing data. One of the available changes is to make your existing partition(s) smaller, so to get some free space on the disk(s) for other purposes. Although you are advised to make a backup before you make any changes to the partitions, I usually practise to 'shrink' NT's partition before I installed anything but NT itself (so, if needed, a repetitive re-installation wouldn't be a problem). Well, Partition Magic (or any other similar utility you are familiar with) will shrink your NT's partition (either NTFS or FAT) to a smaller measure and place it to either the beginning or to the end of the previous measure. It means that you may choose to have your 'shrinked' NT partition at the beginning or at the end of your disk (I usually choose NT to be at the beginning, so the ending part of the disk will become a 'free space'). After the 'shrinkin' is finished, you may re-boot your NT in order to check the new situation: you may use Windows Explorer or Disk Administrator for that. <item>So far so good. Next step is to install your Linux. Case you are familiar with RedHat distribution (I hope with other distros is the same or similar), you start by putting your installation CD in the drive and re-boot the computer). Well, when you are about to choose what type of installation it will be (Gnome or KDE Workstation, Custom, etc.) you may choose whatever you planned before, but I would suggest to install a Workstation at first. This is good because Linux setup will find automatically the free space on the (first) hard disk, make all partitions needed for Linux, format them properly, make majority of options by default so you won't have much pain during the setup (later, if you want, you may either add missing components or re-install Linux as Custom over the existing linux partitions). Lilo should go to the MBR. <item>After it looks that Linux installation is finished, you are going to re-start the computer and there you will only see Lilo with one Linux entry to boot (or maybe more than one Linux entry, in case your hardware is multi-processor one). But, don't panic! Your Windows NT is still there where you had installed it before Linux. You should become some familiar with Linux as soon as possible, in order to be able to find and edit your new /etc/lilo.conf file. When you open this file for the first time, you'll see that there is only one (or more) Linux entry. Well, you should know the exact position (read: a partition) where Windows NT has been installed, so you could add an appropriate entry into /etc/lilo.conf file. After you do that, restart Lilo and, after the next re-boot, you will have both 'linux' and 'nt' entries under Lilo menu. My added NT entry is: other=/dev/hda1 label=nt </itemize> <sect2>2.2.2 If you have more than one (SCSI) hard disk Notice: Folks, you see, at my place, one of computers has several SCSI disks. That's why I put the word 'SCSI' in parentheses. There I have several SCSI controllers, SCSI CD ROM drive and SCSI Tape drive. So, it doesn't mean that *you* will be using SCSI parts at all. You'd rather handle more than one IDE disks, but I hope that install process shouldn't change too much, if any. <itemize> <item>First of all, I would suggest you to install a fresh copy of Windows NT 4.0 on your <bf/first/ hard disk. I suppose that you already made a backup of your important data, so the NT installation shouldn't be a problem. You can easily copy your data on your second hard disk or so. During the NT installation, setup is not going to ask you where to place NT's boot loader, so it would be placed into the MBR (Master Boot Record) of your <bf/first/ hard disk. But, there is a possibility for a previous content of the MBR to remain within the MBR (especially any previous Lilo), so I would suggest you (before installation of NT) to boot the computer with a DOS floppy diskette having DOS version of FDISK. At the prompt a:\ just enter the command: fdisk /mbr and restart the computer again (without that floppy). If you want to be sure about your machine is 'clean', you may also delete any existing partition(s) on your other disks, during the Windows NT Setup <bf/in case you have *not* made any backup on other disks/. <item>After you have successfully installed your NT, you will see that it uses the whole hard disk or a specific partition of the hard disk (depending on what you decided during the setup process). So, it is advisible to 'shrink' the partition where NT resides in order to make some free space on the disk. Onto that free space you will install your Linux. Well, you may also think of using some other disk(s) you have for Linux (so did I). That case, you would start your linux installation and try to use, for example, /dev/sdb (or sdc, or sdd, or else in case of SCSI system) or /dev/hdb (or hdc, or hdd, or else in case of IDE system). Looks like Linux installation accepts whatever you choose, but somehow after all was finished when I did that, LILO was no able to do anything. Actually, it always stopped after 'LI' so it was possible to start Linux at all. Finally, after pulling my hair out, I decided to make it all on the <bf/first/ disk.

Beside that, this version of Linux+WinNT mini-HOWTO is going to offer you another procedure to install both Linux and NT on your computer. And doing that on both IDE and SCSI disks. This mini-HOWTO would be improved from time to time. If you think that the HOWTO on your Linux installation CD is some out-of-date, you may check for newest release on the Internet. It could be found within the main <url url="http://www.linuxdoc.org/" name="Linux Documentation Project"> homepage. <sect1>Credits This version of Linux+WinNT mini-HOWTO is based on: <tscreen><verb> The Linux+WindowsNT mini-HOWTO by Bill Wohler, wohler@newt.com v1.1, 19 February 1997 </verb></tscreen> Any comments or suggestions can be mailed to my email address: <htmlurl url="mailto:m.skoric@eunet.yu" name="m.skoric@eunet.yu">. <sect>Further Information <sect1>HOWTO <nidx>disk!information resources!HOWTOs</nidx> These are intended as the primary starting points to get the background information as well as show you how to solve a specific problem. Some relevant HOWTOs are <tt/Bootdisk/, <tt/Installation/, <tt/SCSI/ and <tt/UMSDOS/. The main site for these is the <url url="http://metalab.unc.edu/LDP/" name="LDP archive"> at Metalab (formerly known as Sunsite). <sect1>Mini-HOWTO <nidx>disk!information resources!mini-HOWTOs</nidx> These are the smaller free text relatives to the HOWTOs. Some relevant mini-HOWTOs are <tt/Backup-With-MSDOS/, <tt/Diskless/, <tt/LILO/, <tt/Large Disk/, <tt/Linux+DOS+Win95+OS2/, <tt/Linux+OS2+DOS/, <tt/Linux+Win95/, <tt/Linux+WinNT/, <tt/Linux+NT-Loader/, <tt/NFS-Root/, <tt/Win95+Win+Linux/, <tt/ZIP Drive/ . You can find these at the same place as the HOWTOs, usually in a sub directory called <tt/mini/. Note that these are scheduled to be converted into SGML and become proper HOWTOs in the near future. <sect1>Local Resources <nidx>disk!information resources!local</nidx> In most distributions of Linux there is a document directory installed, have a look in the <htmlurl url="file:///usr/doc" name="/usr/doc"> directory. where most packages store their main documentation and README files etc. Also you will here find the HOWTO archive ( <htmlurl url="file:///usr/doc/HOWTO" name="/usr/doc/HOWTO">) of ready formatted HOWTOs and also the mini-HOWTO archive ( <url url="file:///usr/doc/HOWTO/mini" name="/usr/doc/HOWTO/mini">) of plain text documents. Many of the configuration files mentioned earlier can be found in the <htmlurl url="file:///etc" name="/etc"> directory. In particular you will want to work with the <htmlurl url="file:///etc/fstab" name="/etc/fstab"> file that sets up the mounting of partitions and possibly also <htmlurl url="file:///etc/mdtab" name="/etc/mdtab"> file that is used for the <tt/md/ system to set up RAID. The kernel source in <url url="file:///usr/src/linux" name="/usr/src/linux"> is, of course, the ultimate documentation. In other words, use the source, Luke. It should also be pointed out that the kernel comes not only with source code which is even commented (well, partially at least) but also an informative <url url="file:///usr/src/linux/Documentation" name="documentation directory">. If you are about to ask any questions about the kernel you should read this first, it will save you and many others a lot of time and possibly embarrassment. Also have a look in your system log file ( <htmlurl url="file:///var/log/messages" name="/var/log/messages">) to see what is going on and in particular how the booting went if too much scrolled off your screen. Using <tt>tail -f /var/log/messages</tt> in a separate window or screen will give you a continuous update of what is going on in your system. You can also take advantage of the <htmlurl url="file:///proc" name="/proc"> file system that is a window into the inner workings of your system. Use <tt/cat/ rather than <tt/more/ to view the files as they are reported as being zero length. Reports are that <tt/less/ works well here. <sect1>Web Pages <nidx>disk!information resources!WWW</nidx> <nidx>disk!information resources!web pages</nidx> There is a huge number of informative web pages out there and by their very nature they change quickly so don't be too surprised if these links become quickly outdated. A good starting point is of course the <url url="http://www.linuxdoc.org/" name="Linux Documentation Project"> home page, an information central for documentation, project pages and much, much more. Please let me know if you have any other leads that can be of interest. <sect>Getting Help <nidx>(your index root)!assistance, obtaining</nidx> In the end you might find yourself unable to solve your problems and need help from someone else. The most efficient way is either to ask someone local or in your nearest Linux user group, search the web for the nearest one. Another possibility is to ask on Usenet News in one of the many, many newsgroups available. The problem is that these have such a high volume and noise (called low signal-to-noise ratio) that your question can easily fall through unanswered. No matter where you ask it is important to ask well or you will not be taken seriously. Saying just <it/my disk does not work/ is not going to help you and instead the noise level is increased even further and if you are lucky someone will ask you to clarify. Instead describe your problems in some detail that will enable people to help you. The problem could lie somewhere you did not expect. Therefore you are advised to list up the following information on your system: <descrip> <tag/Hardware/ <itemize> <item>Processor <item>DMA <item>IRQ <item>Chip set (LX, BX etc) <item>Bus (ISA, VESA, PCI etc) <item>Expansion cards used (Disk controllers, video, IO etc) </itemize> <tag/Software/ <itemize> <item>BIOS (On motherboard and possibly SCSI host adapters) <item>LILO, if used <item>Linux kernel version as well as possible modifications and patches <item>Kernel parameters, if any <item>Software that shows the error (with version number or date) </itemize> <tag/Peripherals/ <itemize> <item>Type of disk drives with manufacturer name, version and type <item>Other relevant peripherals connected to the same busses </itemize> </descrip> Remember that booting text is logged to <tt>/var/log/messages</tt> which can answer most of the questions above. Obviously if the drives fail you might not be able to get the log saved to disk but you can at least scroll back up the screen using the <tt/SHIFT/ and <tt/PAGE UP/ keys. It may also be useful to include part of this in your request for help but do not go overboard, keep it <em/brief/ as a complete log file dumped to Usenet News is more than a little annoying. </article>    <hr>   <ul><li>References: <ul> <li><a name="00133" href="msg00133.html">updates</a> <ul><li>From: "Greg Ferguson" <gferg@hoop.timonium.sgi.com></li></ul></li> </ul></li></ul>   <ul> <li>Prev by Date: <a href="msg00134.html">updates</a> </li> <li>Next by Date: <a href="msg00136.html">DocBook 4.1 support</a> </li> <li>Previous by thread: <a href="msg00133.html">updates</a> </li> <li>Next by thread: <a href="msg00134.html">updates</a> </li> <li>Index(es): <ul> <li><a href="maillist.html#00135">Date</a></li> <li><a href="threads.html#00135">Thread</a></li> </ul> </li> </ul>    </body> </html>
