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.
