Serious computer problems

[twasik4]

Okay. So last saturday my computer started to freak out and became really slow all of a sudden. My first thought was i was doing too much. But with everything close i had a sudden 371 viruses that had just randomly appeared. First thing first i unplugged my harddrive and did a quick virus scan for a half hour and it took care of about 350 of them. I ran a full virus scan with my harddrive for about 5 hours after it. Which time i actually fell asleep at my laptop. When i woke up that morning i noticed it had taken care of a other like 60-70 viruses. Happy. But retardedly i restarded my computer. Big mistake because now it does its initial OS boo but then goes to a black screen. I tried safe mode but it doesnt work. It says:

Multi(0)disk(0)rdisk(0)partition(2)\WINDOWS\system32\ntoskrnl.exe
Multi(0)disk(0)rdisk(0)partition(2)\WINDOWS\system32\hal.dll
Multi(0)disk(0)rdisk(0)partition(2)\WINDOWS\system32\KDCOM.DLL

I tried to boot to last working configuration and doesnt work. Any help please? At the moment i am thinking reformatting is the only way to go.

It looks like your computer is missing hal.dll which isn't good news.

When I first started using Linux I installed it alongside Windows but I didn't defrag my hard-drive first & I couldn't reboot my computer because the hal.dll was overwritten.

You might want to try looking here as it shows you how to reinstall ntoskrnl.exe which also appears to be missing or damaged.

Haha. After a month of trying, I finally got my Windows 7 to install.
It took me 10 days to backup my documents on a flash drive, bridge them over to my other computer, and repeat. I planned on backing up all 70 Gigs, but ended up wasting only 10. I also made a list of all installed programs and utilities from linux. That's the slow way. I had no way to transfer over the network, since it had timeouts. I just couldn't seem to transfer it over a 100(or 10) Mb/s cable, so I gave up and used a flash drive. If you organize your computer correctly, it's a bit easier. This was again caused by my broken Ubuntu netbook iso installing. I deleted its partition, which had GRUB on it. From there, to only way to boot the thing was from LAN or USB. After trying to fix it, I installed GRUB and tried to fix Windows. Abridged, if Windows doesn't work, don't try and repair it with linux unless you know what your doing. I believe the broken iso broke at partition resize. That's a big Uh-oh.
