Windows 7 not starting up

[SunFlowerSeeds]

Hey I recently installed poweriso and magicdisc on my computer then I rebooted but windows started to hang at shutdown so I just forced a shutdown, now windows is hanging up upon restart and the same happens for safe mode. I'm thinking the problem might be magicdisc cause it said drivers were not found and safe mode was hanging around the loading drivers part or that I made a virtual drive. Please help and thanks in advance.

Also I'm attempting to do a system repair via windows disc but I don't know if this will help.
Edit: Windows repair just finished and the problem signature was

You are running old windows 7 with out updates installed no service pack 1 ??
Sometimes startup repair needs to run up to 3 times with reboots in between
If that doesnt work you could try a repair install
