Can't Boot Windows with ANY Rescue CD!

[technomann]

Suddenly and for no apparent reason, I cannot boot into my Windows 7 PC. I am running Windows 7 Home Premium 64-bit dual boot with Linux Ubuntu. On boot up most of the time I cannot even get to the GRUB boot loader. I just get a blank screen, sometimes a blinking cursor up in the left corner. I cannot boot from the Windows 7 install DVD. It starts to load windows files then freezes. I have downloaded and burned about half a dozen "Rescue CD" iso images, from AVG to Avir to Norton to Paragon Rescue Kit, etc., etc. -- all to no avail! Either they won't boot at all or they freeze during the process. I even created a couple of bootable rescue USB flash drives. Nothing works!!! Once or twice I managed to actually start a virus scan with the AVG Rescue disk, but then the scan aborted before it could even get going. It's like something keeps killing the scan. I can't even get into my BIOS! It just freezes when I hit the F10 key. What the heck is going on and how can I fix this? Is this some really nasty boot sector virus or perhaps a hardware failure? I just replaced the HDD a few weeks ago, so I don't think it could be that. Any and all ideas GREATLY appreciated!

Try these free, bootable hardware diagnostics:

Please start by running these bootable hardware diagnostics:

HD Diagnostic (read the details at the link)

Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Malware (read the details at the link)

If you can't get into the BIOS to change the boot order, try removing the hard drive and seeing if you can boot that way.
