The problem is, that running and installing 12.10 doesn't work. I've done following tests:

  • Installed 12.10 32-bit. It's working.
  • Installed 12.04 LTS 64-bit. It's working.
  • Upgrading from 12.04 64bit, to 12.10 using do-release-upgrade -d. This did not work.
  • Burn a 12.10 64-bit CD. Installed to another PC, which worked. But booting this to the PC didn't recognize this. The error message is: "No operating system found". It the proceeds to boot from 2nd priority.

The PC is a Packard Bell Easynote LM:

  • AMD Phenom II X2 N660
  • 6GB DDR3 RAM
  • 640 GB HDD.
