Windows 8 failed to boot.

I have a Lenovo G580 laptop 2gb RAM, i5, and 500gb HDD. It had windows 8 RTM 32 bit installed on its C drive. It had come with DOS preinstalled so I had to do a fresh install of windows 8 via bootable usb. It worked well for few months but now it refuses to boot and goes into "automatic recovery mode" and then it says that your pc needs to be repaired with a recovery disc.

I did not made any recovery disc when it was working so I tried to do a fresh install of win 8 and then win 7 via bootable usb, but both have failed. The screen freezes after blue logo of windows appears and then it restarts saying it has encountered an error and needs to be restarted.

I have tried booting it in safe mode along with all other options on start-up menu but it doesn't help.

Please help.

If you can get to cmd which I believe you can from one of your USB versions of Windows when you go to repair cmd should be a option. Then Try.....

chkdsk c:/r
