My desktop is 12.04 64bit, and it cannot boot from the hard drive anymore. When I attempt to it just is stuck on a blank screen with an blinking dash, and nothing happens.

I checked with the bios trouble shoot for problems and it said that no boot path could be found. I do not know why this is happening, but need to fix it because it used to boot up normally. What I need to know is how to fix it.

I can boot into a live DVD. Also, there were a few boots I would attempt to boot into a live USB, then it would boot to the hard drive, but that does not work any more. So with the live DVD (it is an 10.04 LTS 32bit), is there any means to correct the boot path from the live DVD?

Thank you for your time and answers.
