Compression error

[Cyberdryne]

Hello everyone, I'm a new member and will try to be a part of this community and sorry if this has been repeated or not. Ok heading on to the problem, I'm not much of a tech freak but I seem to have this problem after I tried compressing my drive C which has all the Appdata and important functioning systems however the thing is, it was literally hogged with it thus somehow reducing it's reliability, so I was just poking around the 'Computer' and I found for that drive that I could compress it to make some memory space available so it could run faster but ever since I did it I have been receiving the error whenever I tried starting my PC (check image) please help me out, I can't even enter in safe mode and can only access by boot menu and start-up menu which I have no knowledge of knowing what to do with it, could this be the end of my PC? (Also I directly tried searching the error on Google only to get a company that makes stockings for women )

so I was just poking around the 'Computer'

Guaranteed to cause problems.

Sounds like some of the boot files got compressed by mistake and the BIOS doesn't know how to handle them to start the booting up. Might read this page:
SOLVED: Win 7 Error - 'some file' is compressed. Press CTRL+ALT+DEL
It's very possible you may be looking at a reinstall of Windows. What I usually do is boot to a Linux Mint LiveDVD and do file management from it but it may not be able to decompress the file/s, always worth a try. It's also a good way to Copy your data files to a different drive.

Did you make the Win7 Repair disc? If not you may be able to use one from a computer with the same version, 32-bit or 64-bit.

You should never compress your c drive in W7

I can only access my startup menu and boot menu BTW not the repair computer function/windows recovery option
