Ubuntu 8.04 is on my primary master hard disk
XP sp3 is on my primary slave hard disk
I installed ubuntu after the xp
and the grub is on the master hard disk
so xp is not altered by ubuntu at all

my computer is dimension8100
so the first partition on slave hard disk is dell rescue tool partition(or something like that)

my problem is when i select boot xp from grub menu
i got a black screen and no hard disk is reading/writing

can any one help pls?

P.S. if i replace root with rootnoverity, it reboots after i select boot xp!

Hi browntux

Have a look at

http://www.gnu.org/software/grub/grub-legacy-faq.en.html#q10

It seems to suggest that you should have root(hd1,0) and not root(hd1,1). But do have a look around the help at

http://www.gnu.org/software/grub/

particularly

http://www.gnu.org/software/grub/manual/

and also check out (in a terminal)

man grub

to make sure you understand what you are doing. It is normal to boot XP from the first partition on your primary drive.

dear sir,

my xp resides on the 2nd partition of the sdb
Device Boot Start End Blocks Id System
/dev/sdb1 1 4 32098+ 6 FAT16
/dev/sdb2 * 5 4862 39021885 7 HPFS/NTFS

that's why i set it that way

Please try change your /boot/grub/menu.list open a terminal and type

sudo gedit /boot/grub/menu.list

give your user password when requested, you don't see nothing when you type it, then press enter.

Remove the rows:

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

save and exit. then type:

sudo update-grub
sudo reboot

and try...

Hope this helps
