My computer case has a slot on its top where a disk can be inserted. It is wired to one of the motherboard's included SATA ports (8 total I think). A while ago I needed to look up something on the drive (a 2.5in SSD), plugged it in and mounted it on /mums (name of the defunct computer). It was sitting there mounted for over a month I suspect. It does include the old computers /boot as well as the root file system. Of course the root fs contains a /boot, it would appear as /mums/boot. I don't recall if I had any reason to mount "mums" /boot. I think not. > If you physically added a another disk it may be booting from the > wrong disk and/or the added disk may be confusing grub in some manner > because it is an earlier device than the real boot disk. That is my thought as well. I'd pulled it before updating initramfs and grub from the live system.
