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:

ubuntu appears in BIOS menu

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?

does the link you provided not help?! And maybe you should contact your laptop provider/manufacturer. But maybe resetting or flashing your bios will help? If you need help with that, we can always try to help you. –  Dr_Bunsen Oct 28 '12 at 21:48
I replaced bios battery for 1hour but only time got errased. I trier to use in BIOS Load Bios Default Settings but get black screen and shut down laptop after couple of minutes. Please advice what else can I do? I'm going to contact Lenovo but I don't think the guarantee covers it. –  user101751 Oct 28 '12 at 22:28
well, if they make crappy bios that fails, they have to fix it, but can't you download a bios update from lenovo and flash that ver the current bios? If not, I am out of ideas, never saw this before. –  Dr_Bunsen Oct 29 '12 at 7:00
Well, not mentioning I have no idea how to flash bios there is one thing that wonders we how could I do it as bios show no external device to boot. Even if I have it on USB or CD a can't select it in bios to boot. –  user101751 Oct 29 '12 at 7:59
wow, I think you have to return it to the manufacturer, since this isnt supposed to happen. I can't help you, I am sorry for that, and I hope it all works out. –  Dr_Bunsen Oct 29 '12 at 13:55
