Note that strange unusable first part (because HP does strange things during Windows 7 installation ??). I edited the grub menu.lst file. The only thing i modified is uncommenting the Windows part. Here is what I have:
# (2) Windows 7 title Windows 7 rootnoverify (hd0,0) savedefault makeactive chainloader +1
When I reboot my computer and select the Windows 7 item, I get the mesage:
grub file system type unknown
partition type 07
If I use in menu.lst (hd0,1) instead of (hd0,0), same problem, same error message.
I tried to look at the same problem with google, without any success.
Does someone know what the problem is, and if there is a solution ?
