Since your su is acting like it's from beowulf, you should probably treat
it like it is. Did you try using 'su -' instead of 'su'? If not, then
using the full path should work:
/usr/sbin/grub-install

To test the drive, install smartmontools (on the new system) and run
'smartctl -a /dev/sda' (or /dev/sdb, or do both.)

I'll bet your registry is exactly where it needs to be. (Reminds me of the
guys who call me up to say my computer might have a virus.) Maybe you need
better shielding on your browser. (noscript, ublock, something else?)
