Re: weird stuff about grub2
I have similar problems.
I had a squeeze system where I added a new harddisk and installed a new
variant of squeeze. Accidently the new installation added grub to the master
boot record of the newly added harddisk.
With the old grub it was no problem at all - I just had to run 'update-grub'
and things where fine.
The osprober added menue entries for the other systems found, but none of them
is bootable. Selecting another item results in errors like:
error: no such device xxx-uid-xxx
error: no such partition
error: you need to load kernel first
So to boot one of the older OSses installed, I need to enter BIOS and change
the boot order of the harddisks. That's really ugly!
When I look at the disk with the claimed uid - it exists and the uid is right.
So what can I do, to add the older OSses to the grub2 of the new installation?
(I already tried update-grub - but did not change anything)
