Serious os install problems. Help very needed.

Specs: Windows 7
So I had a computer with both win 7 and win 8 (preview) installed on a 1TB partitioned hd. This had been going on fine for a while, then I installed mcafee total security and did a scan, it detected a few viruses and said to restart, so I did. After the restart windows 7 failed to boot and I was directed to the startup repair. The startup repair worked and I rebooted but mcafee was uninstalled. I reinstalled mcafee did the same scan and rebooted. Same thing happened except the startup repair said there was a problem it could not fix.
So I decide I'll do a proper recovery on this thing and whap out my windows install cd, plug it in and it says the version of system recovery is not comparable with the version of windows I am trying to repair. I think to myself, okay if windows 8 works I guess I'll stick with that for a while until I can figure this problem out - except then I realise I hate everything about windows 8 and I decide to try to install 7 on top of the old 7. In the end I accidentally installed over windows 8, but then I install it over the real 7. Bottom line, since then everything I turn my pc on now it loads the bios screen then waits a while then turns off. I then tried running Ubuntu off a live USB, that doesn't work, same with a live DVD. I checked these on other systems and they work fine. On my computer they go to the Ubuntu menu saying, try, install, memory check, ect but after that it goes black with a flashing cursor in the top of the screen.

So yeah, pc is now totally dead, any suggestions welcome. Help.
Thanks, Adam.

Well, what is it you would like to do from here? Have both OS's running on each of the partitions or just one and have the other partition as data drive?

Either way you're going to have to start over fresh if you want to do this right.

Maybe true, but not very helpful.

Test your memory with memtest first via bootable CD (download ISO image and burn to CD). Let it run all tests unless you get errors of freezing. Retest with one stick of memory at a time to confirm problems.
Test your Hard Drive (after memory) with hard drive utility from hard drive manufacturer (download bootable version and burn to CD).
If memory tests OK proceed with the hard drive test, If it will not run at all, it still may be a memory problem, but it might also be a power supply problem, especially if memory test will not run with either one stick in either slot, and especially if you have trouble getting into BIOS set up.
Report back results for additional advice.

You have to be a little bit crazy to keep you from going insane.
