I have a dualboot computer with Windows Vista (on hd0) and Ubuntu 9.10.
The bootloader is GRUB and
the windows bootloader lets me decide between Vista and Ubuntu-Installation (broken WuBi). But now (i don't know why that changed) I can't use start
the windows-bootloader anymore. I tried "ls" on
the grub-prompt and it gave me a list like:
(hd0) (hd1) (hd1,0) (hd1,1) (hd1,2) ... (fd0)
It recognizes all partitions of hd1 (the ubuntu-harddisk) but not of hd0(the win-disk). .. WHY?
Here is
the result of
the "boot info script" for
the technical details:
