Hi All

I have got 3 hard disks (40,80 and 500 gb).I first installed Win XP on 500gb disk,and later i put ubuntu(8.04) on the 80gb one.
When i start the comp(booting from 80gb one),the Grub screen comes up with options of ubuntu and Win Xp,but the windows does not load.

I get Error 13:unexpected format something
The entries in menu.lst files are below:
## ## End Default Options ##

In the menu.lst, try changing "root (hd2,0)" to "rootnoverify (hd2,0)".

no luck changing to rootnoverify (hd2,0) also...even though entries match the disks...dont know what could be the problem..

Perhaps it's hd1 and not hd2? GRUB can be funny about that sort of thing sometimes

so finally solved the problem...my bios setting didnt reflect the drive order...so my 2nd drive was set to 40gb instead of sata 500gb...hence was unable to boot...
i never gave a thought that BIOS setting was related to linux booting....
so now i can switch OS w/o having to change BIOS each time..
