[gentoo-user] about multiboot with grub

[askar ...]

Hello!

I have 2 hard disks in my PC.

On the 1st one, /dev/hda, I have Gentoo and Windows XP.
On the 1st partition of the 2nd hard disk, /dev/hdb1 , I have Windows 2000.
I want to include this in my grub.conf, but it doesn't go well.

When I click on Windows 2000 of the grub menu Windows XP of the 1st
hard disk starts up.
I think, mayby problem with chainloader parameter...
My grub.conf as follows:
-----------------
# Boot automatically after 30 secs.
timeout 30

# By default, boot the first entry.
default 1

splashimage=(hd0,1)/grub/splash.xpm.gz

title=Gentoo Linux
root (hd0,1)
kernel /kernel-2.6.7-gentoo-r11 root=/dev/hda3 vga=792

title=Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1

title=Windows 2000
root (hd1,0)
rootnoverify (hd1,0)
chainloader +1
-------------------------



Sincerely,

Askar

Get rid of the "makeactive" line -- it's unneccessary, and may cause
you no end of headaches... What that line does is change the "active"
(bootable) partition - in this case, to your WindowsXP partition which
probably isn't what you want...

Get rid of the "root (hd1,0)" line -- it's unneccessary (and may be
what's causing your problem)...

You can try using the "map" command to swap the drives around (as far
as the BIOS/Windows is concerned):

title=Windows 2000
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
chainloader +1

...would make your BIOS/Win2K to think that /dev/hdb is /dev/hda, and
vice versa. Most versions of Windows that I've messed around with
require being installed to a primary partition on the first hard disk.
This solution works around that limitation.
