I have an SSD with Windows 7 and Linux Mint 22. I also have an HDD with Lubuntu and LMDE6. LMDE works great, but it's slow on a HDD, so I want to move it to the SSD, and then remove Linux Mint 22 on the SSD.
I don't want to do a fresh install once again. So here's what I did: I cloned the LMDE partition to the SSD, booted into LM 22 and ran sudo update-grub.
While it did add a LMDE6 (Faye) on /dev/sda6 to the grub menu, choosing that option always boots up the LMDE on the HDD. With my HDD plugged out, it gives some error like “access to root account is locked.”
And I understand why that happens: the grub.cfg from LMDE that I cloned, still has things like set root hd1,gpt3. But it also has a ton of other things in it, so I don't know what exactly I could change.
What do I have to do so that this problem is solved in the way I want?
