Ive cloned my ubuntu installation, but cannot get grub2 to see it.
Before I had the install on /dev/sda1 and a grub boot prtition on /dev/sda2
I copied them both to a new disk - now boot prtition is on /sdb1 and the cloned partition (using gparted) is on /sdb2
Ive set the BIOS boot order ot boot from the driv ive copied to. At startup the first time it booted into the old install (this was expected, since I hadnt changed the grub entries)
But now, while in my 'old' installation, if I run grub-mkconfig it only finds the install on /dev/sda1, and not its copy on /dev/sdb2
Ive tried reinstalling grub from scratch but no joy....
