+NT OS Loader + Linux mini-HOWTO +Bernd Reichert, <reichert@dial.eunet.ch> +v1.11, 2 September 1997 + +Abstract +

+This document describes the use of the Windows NT boot loader to +start Linux. +This procedures have been tested with Windows NT 4.0 WS and Linux 2.0. + +How does the NT OS Loader work +

+The NT OS loader likes to have the boot sector from the other +operating systems available as a file. It reads this file and +starts the operating system selected, i.e. either Windows NT in +different Modes or any other OS. + +Tips on how to install Windows NT and Linux on the same System +Windows NT installation +

+Try to install Windows NT first. If you want to use NTFS for your Windows +NT-partition, keep in mind, that the todays production version of Linux +cannot access NTFS partitions. +An alpha driver that can read NTFS-Partitions is available at +http://www.informatik.hu-berlin.de/~loewis/ntfs. +You may create a separate FAT-Partition for data exchange +or you have to use DOS-formatted floppies. + +Partitioning +

+Another Mini-howto recommends not to use NTs "Disk Administartor" +to create the Linux swap- and root-partitions. It is sufficient to +see the free space there. I also recommend to use linux's fdisk later. + +Linux installation +

+Now boot linux from diskettes, create the swap and root-partition. +Fdisk assumes the ntfs-partition to be a HPFS-partition. +This is normal. +Boot again from diskettes and install Linux as you like. + +

+Just in case the installation procedure suggests that you could mount +the HPFS partition which it has found: Ignore it. + +Lilo +

+When you come to the Lilo-Section, specify your Linux-root-partition +as your boot device because the Master Boot Record (MBR) of your +harddisk is owned by Windows NT. This means that the root-entry and +the boot-entry in your /etc/lilo.conf have the same value. +If you have a IDE-harddisk and your Linux-partition is the second +partition, your boot-entry in /etc/lilo.conf looks like: + + +boot=/dev/hda2 + + +If you have two disks and your Linux resides on the first partition +of your second disk, your boot-entry in /etc/lilo.conf looks like: + + +boot=/dev/hdb1 + + +Run lilo with a kernel that matches your system. +Check the kernel by booting from diskette first if you are not sure. + +

+If you cannot boot Windows NT now, you have a problem. +I hope you have created a repair-disk recently. + + +Bootpart +

+There is a NT-programm called bootpart written by G. Vollant that can do +the jobs from the next two points for you. Bootpart is available at +http://ourworld.compuserve.com/homepages/gvollant/bootpart.htm. + +

+If you want to know how things are working together, use the procedures +described in point 5 and 6. + + +The Linux part of the work +

+You have to boot from diskettes until the NT-part is fixed. + +

+Now you have to peel the bootsector from your Linux-root-Partition. +With /dev/hda2 as your linux-partition, the dd-command is: + + +# dd if=/dev/hda2 of=/bootsect.lnx bs=512 count=1 + + +There is something wrong if your bootsect.lnx has more +than 512 bytes. + +Now copy the file bootsect.lnx to a DOS-formated floppy if this is +your way to transfer files to the NTFS-Windows-partition. + +You can copy it with + + +# mcopy /bootsect.lnx a: + + +or with + + +# mount -t msdos /dev/fd0 /mnt +# copy /bootsect.lnx /mnt +# umount /mnt + + + +The Windows NT part of the work +

+Copy the file from the diskette to C:\\bootsect.lnx. I don't tell you +how to do that. + +What lilo.conf is for linux is c:\\boot.ini for Windows NT. +Remove the, system- and the read-only-attribute before you +can modify it with: + + +C:\attrib -s -r c:\boot.ini + + +Now change the file boot.ini with an editor, notepad for example, as follows: + + +[boot loader] +timeout=30 +default=multi(0)disk(0)rdisk(0)partition(1)\WINNT +[operating systems] +multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ... +multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ... +C:\BOOTSECT.LNX="Linux" + + +Only the last line has been added in this example. +Restore the attributes after you have saved boot.ini with: + + +C:\attrib +s +r c:\boot.ini + + +After a shutdown of your Windows NT and a restart your should +see the following: + + + OS Loader V4.00 + + Please select the operating system to start: + + Windows NT Workstation Version 4.0 + Windows NT Workstation Version 4.0 [VGA mode] + Linux + +Select Linux and see + + LILO loading zImage .... + + + +Play it again Sam +

+A new copy of bootsect.lnx must be transfererd to C:\BOOTSECT.LNX +evry time the bootsector of your linux-partition has been modified. +This happens for example when you install a new kernel with lilo. +As you can see such a system in not ideal for testing experimental +kernels. + + +Troubleshooting +

+If things do not work as expected, check bootability with a floppy disk. +With /dev/hdb1 as your Linux-partition, your /etc/lilo.conf +has the following entries: + + +root=/dev/hdb1 +boot=/dev/fd0 + + +Run lilo with a diskette inserted. Now try to boot from the diskette. +If your Linux on /dev/hdb1 can't be +started, the NT OS loader will also fail to start it. +If you see a lot of 01 01 01 01, your root-disk is not accessible. +Check whether all your disks are known by the bios. + +

+If the floppy boots your Linux partition, you can peel of your +boot-sector for the NT OS loader with: + + +# dd if=/dev/fd0 of=/bootsect.lnx bs=512 count=1 + + +

+You can keep this diskette as your rescue-diskette just in case +your Windows NT installation breaks. + + +References +
