Hello, 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. Not now. 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) kind regards Gero -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
