Boot windows from second HDD

[mip]

How do I configure GRUB to boot windows from my second HDD? My first HDD has Fedora (Primary/Master) and my second has Win98 (Primary/Slave).

grub.conf currently looks like this:

title Fedora Core (2.4.22-1.2174.nptl)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2174.nptl ro root=LABEL=/1 hdc=ide-scsi hdd=ide-scsi rhgb
initrd /initrd-2.4.22-1.2174.nptl.img
title Windows
rootnoverify (hd1,0)
makeactive
chainloader +1

Cheers.

My grub line for a window dual boot machine I have lying around is:


title Windows XP Professional
rootnoverify (hd0,1)
chainloader +1

[mip]

But I'm trying to boot windows from the first (and only) partition on the second HDD so shouldn't I be using:

rootnoverify (hd1,0)

Maybe I need to use the map command. I didn't think this would be necessary as there are no windows partitions on my first HDD.

I was just showing I that I didn't have makeactive in my setup.

Ah right. Thanks. I'll give it a go.

Removing the make active doesn't help. I now have:

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2174.nptl)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2174.nptl ro root=LABEL=/1 hdc=ide-scsi hdd=ide-scsi rhgb
initrd /initrd-2.4.22-1.2174.nptl.img
title Windows
rootnoverify (hd1,0)
chainloader +1

Any Ideas?

Could you paste your results from:

fdisk /dev/hda once you have typed 'p' for print.

Mine is:

Command (m for help): p

Disk /dev/hda: 80.0 GB, 80026361856 bytes

And your result from the command, with no options: mount

Mine is:

Also, the Grub manual expands on the windows options, so you can understand the various parameters a little more:

Grub Manual (http://www.gnu.org/software/grub/manual/grub.html#DOS%2fWindows)

[Jman]

Windows doesn't like not being on the first partition of the first drive sometimes. Check out this (http://www.fedoraforum.org/forum/showthread.php?s=&threadid=975) (long) grub howto. The part about the 'map' function of grub is relevant, I think.

You will either have to switch the drives around or do some map magic, something like:

title Windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
makeactive
chainloader +1


grub documentation is also available with the 'info grub' command.

Like Jman said, I think you should try with the 'map' command.
In your case, the Windows' lines in GRUB should be:
title Windows 98 SE
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
rootnoverify (hd1,0)
chainloader +1


Explanation of some commands:

map

Command: map to_drive from_drive
If you have installed DOS (or Windows) on a non-first hard disk, you have to use the disk swapping technique, because that OS cannot boot from any disks but the first one.

Map the drive from_drive to the drive to_drive. This is necessary when you chain-load some operating systems, such as DOS, if such an OS resides at a non-first drive. Here is an example:

grub> map (hd0) (hd1)
grub> map (hd1) (hd0)

This performs a virtual swap between your first and second hard drive.

Caution: This is effective only if DOS (or Windows) uses BIOS to access the swapped disks. If that OS uses a special driver for the disks, this probably won't work.

makeactive

Command: makeactive
Set the active partition on the root disk to GRUB's root device. This command is limited to primary PC partitions on a hard disk.

Good Luck!

Thanks for the help everyone. Got it working with the following entries in grub.conf

title Fedora Core (2.4.22-1.2174.nptl)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2174.nptl ro root=LABEL=/1 hdc=ide-scsi hdd=ide-scsi rhgb
initrd /initrd-2.4.22-1.2174.nptl.img
title Windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
chainloader +1

Nice info there. ;)

Resolved.

Thank you very much..... worked also on a computer with Red Hat 9 (IDE1, master) and Win98 (IDE2, master)
Windows is becoming an "optional" OS, even if they don't like it!!
