multi-boot help

alright, this is where i am. ive had gentoo installed and running as the only os on my computer for the last month or so. i decided to reinstall win2k to play some games with my wife. i knew it was going to overwrite my mbr and was ready for it. i think my bigest mistake was when i installed windows, i installed it on my second disk instead of the first disk. when in installed it made me make a small (106 meg) partition on disk one. (thats the size i made it. it only used like a meg)
i used a boot disk to reinstall grub on my mbr, and got my linux installation going again, but now i cant get grub to boot windows. here is the output from a cfdisk for each of my hard disks
/dev/hda
cfdisk 2.11y

ive also tried

and

i always get an error saying something about filesystem type 82 and that it cant boot or it cant find it. ill try it again and post the error

no, its 0,2. when i put in the partition i robbed from my 1.5 gig swap that i had set up on hda2, so the partition that windows wanted on hda became hda2 and my swap became hda3. thanks for the quick reply tho

Jimbow · Posted: Sun May 04, 2003 6:13 am Post subject:

Grub numbers partitions starting at 0. So:

hda1 -> 0,0
hda2 -> 0,1
hda3 -> 0,2

etc.
