ben ya un bout de temps j'avais recupere cela :
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.
1 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.
2 Tips on how to install Windows NT and Linux on the same
System
2.1 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.
2.2 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.
2.3 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.
2.4 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 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.
3 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.
4 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
5 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 ....
6 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.
7 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.
