I've just started with Ubuntu and reach total dead end. After installing Ubuntu 12.04 64bit on laptop Lenovo B580 (freeOS), I found out after few days that the BIOS boot list is lost. All available boot devices like CD, HDD, LAN or USB are not listed, instead there is added Ubuntu position like in below link:
I decide to format my HDD counting on resolving the problem, but as there was no boot option to start from external source. I swap the disk to second laptop and installed Windows 7. Unfortunately, this only worsen my situation as this didn't help to get back BIOS boot list, additionally I now can't boot with choosing the only position that is left in the BIOS which is Ubuntu.
Please advice on how can I fix this. Did I wrack my laptop?
