Yes, they are both connected

Never used UUID in fstab. Do I just run: blkid|grep UUID
and copy it to fstab.

I just copied the whole MBR to a new disk and it worked, the system
boots, but nothing can be compiled.
I would confirm that you are really booted from the new disk and not
the old one. It is possible that the MBR from the new disk was used to
boot, but if /etc/fstab says /boot is mounted from /dev/sda1 then that
does seem wrong. I almost always put an empty file in the root of each
partition named for the disk/partition just so I can be sure what's
actually mounted. Is /etc/fstab identical on both disks? What does
fstab say about where / is mounted from?
