If you run Sparky installed on a hard drive, find package 'grub' in Synaptic, mark all installed grub packs for reinstalling.
There are 4 or 5 packages installed already so reinstall theme. That's all.
This is the easiest way.
Thanks pavroo. You are right - it was easy to do. However, the problem has not been resolved. To start from the beginning:
The power supply of a desktop computer failed after 3.5 years and was replaced. However, the 2 identical hard drives were connected in the reverse order (what had been sda was recognized as sdb, which prevented Sparky Ultra from recognizing the user account's /home partition).
Meanwhile I entered openSUSE (which I hadn't been using), which updated it's system and took over the Grub.
But - I then reconnected the hard drives so that the original disk identities were restored (sda as sda etc. - which allowed Sparky Ultra to return to normal) and proceeded to reinstall Grub as you recommended. Four files were reinstalled:
- grub-pc-bin (and)
At the end of the re-installation I was asked where I wanted the Grub installed and I checked sda (although Sparky Ultra is on sdb15, the grub had always been on the mbr of sda).
But that didn't work. Using a SuperGrub2 boot disk for 2011, I re-entered Sparky and reinstalled grub once again. And again. But with the same results (except I wasn't asked where I wanted the grub installed again), which reads as follows:
Welcome to Grub
error: unknown file system.
Entering rescue mode...
Apparently, I am still goiing to have to code - or install an alternative bootloader. (At present, I must use a Super Grub2 boot disk to load the OS).
(I attempted to change the boot preference order for the two hard drives in the BIOS - Award BIOS v. F7 for a Gigabyte X58A-UD7 but observed no change - of course the drives are identical).
(openSUSE Gnome is about the only other system I ever use on that computer, although LMDE, Solus, Point and Neptune -all Debian deriitives- are also installed).
