More detail now I think I have my posting sorted out :-) What I have: /dev/sda 64GB MBR SSD with Windows 7 64 bit, and GRUB2 as boot loader. /dev/sdb 750GB MBR HDD with Ubuntu installed - GRUB2 chain loads from /dev/ sda. /boot/grub is on this drive. What I want to have /dev/sda 64GB MBR SSD with Windows 7 64 bit, and GRUB2 as boot loader. /dev/sdb 3.0TB GPT HDD with Ubuntu installed - GRUB2 chain loads from /dev/ sda. /boot/grub is on this drive. What I have done so far: [various mis-steps left out] Set up the 3TB HDD in Windows 7 as GPT. Created the ext2 and swap partitions on the 3TB drive using gparted Copied the partitions from the 750GB drive to the 3TB drive. Unplugged the 750GB drive. When I boot, I get (no surprise) the grub rescue prompt. However when I search for partitions to boot from I can only see the MBR disc. I cannot see any partitions on the GPT disc. I can see in grub.cfg (from /dev/sdb) insmod part_msdos insmod part_ext2 set root=(`hd1,msdos1)` which I think may mean that grub is only looking for MBR drives but I'm still getting into all this. My main problem is that I would expect grub rescue to list all the partitions it could see (at least all the partitions with an OS installed) so I could then select the correct partition and boot up into Linux, then run grub-update (and possibly `grub-install /dev/sda`) to get the new drive properly identified. So can someone please tell me if what I am doing is not catered for, or which simple step I've missed out.
