I just imaged a Windows partition onto a new drive with dd. Then I changed the NTFS UUID to a new one. Then I ran update-grub (using grub2) and restarted.
Now there is a new menu entry in the Grub menu corresponding to my new cloned drive - but when I boot it, it boots the original windows drive!
I have checked that the drive path (/dev/sdd1) and the volume UUID are correct in the new grub.cfg.
Do you know where I can find some logs or anything indicating what is wrong with my drive clone, and why Grub seems is booting the original Windows drive instead?
Thanks, Louise
