Grub won't boot that "OTHER" OS

Kosano · Guest

I have gentoo installed and working fine. My setup is i have 3 hard drives, 1 on hde, and
1 on hdg and hdh. They are on a promise ata100 controller so that is the reason they
aren't on hda and what not.

So linux has been working fine and i decided to install windows XP yesterday (since Bioware
didn't release the nwn linux client at the time of launch......) So i installed WinXP on a 20gig
fat32 partition on hdg1. Then i added a line to grub that looks like

title=Win
root (hd1,0)
makeactive
chainloader +1

but when i try to boot from it from grub it just sits there with the text on the screen and
does nothing. I took out the makeactive but it still won't boot. When i go to the commandline
from the grub screen and type root (hd1,0) it recognizes it as a vfat partition but when i type
chainloader +1 and then type boot it just sits there and does nothing.

Also i should note that the way that i installed windows (if this makes a difference) is i
unplugged my linux drive (hde) so i wouldn't have anything unfortunate happen and only had
hdg and hdh running, then i installed WinXP and everything went fine. So now if i unplug
hde then it will boot into windows just fine but it won't boot from grub.

Any suggestions would be greatly appreciated.
Thank you

Hi,

If Windows is on hde (and assuming that all your IDE channels on your mobo are used) then "hde" would translate to (hd4) in grub. Upon bootup, Windows likes to think that it's on the first hard drive, but you can fool it if it's not. I have Win2k installed on the first partition of hde, and this is my entry in grubs menu.lst file:

ok, so i am going to add

map (hd1) (hd0)
map (hd0) (hd1)

i got that part, now will i leave the same line

root (hd1,0)
since i am trying to boot windows off of hdg1 which is hd1,0 or so i need to change
it to be
root (hd0,0)
since i just maped (hd1) to (hd0) ?

Thanks a lot for all the help. You guys are great.

Yes, that is correct.

well I don't know if GRUB recognized fat32 or not blah blah... but I was wondering have you tried using

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

instead of root(hd1,0)

note: as long as root /rootnoverify appears before the map command you can still use (hd1,0).

hope that helps
