I'm doomed

So I got an message from my AV saying that I had an Trojan horse and i should put it in my valt, so I did. About 15min later my computer restarted itself, and before it got to the starting windows bit, it said missing operating system. I tried doing a start up repair, and it said it was repairing some disk and it would take an hour to fix. After about a minute it said there was an error. I don't know what else to do. Im guessing i have no operating system, does this mean all my files are gone?? I have nothing to back up with so I had no back up.

Any help welcome

Well, if you have kept an image of the C drive then now is the time to restore it.

If you have not then instead of struggling to repair the System just clean reinstall Windows. That is because I hold the view that no repaired system is better performing than a clean install.

Do you have any usb devices plugged in (like a flash drive) sometimes a system will try to boot from it and you'll get that error or if you have a CD in the drive and your CD/DVD drive is the first drive. Go into the BIOS and make sure your hard drive is in the boot loop.

If you have another computer you can pull the suspect hard drive, install it in an external enclosure and run chkdsk /r on the drive and also scan it for viruses.

As already stated, if the repair does not work do a clean install and don't waste hours on struggling to fix a hosed OS.

You all say to do a fresh install of windows... But what will happen to my data D:

I'm trying to do 3 repairs now, and I will do the command prompt later today when I get back from my part time job.

I doubt any will work, because in the windows installer it doesn't show any windows installed at all. It's like the virus uninstall it

Nope. I'm not wasting my money on an externial haha, and then mum doesnt want to waste like $50.
I did use to half my hard drive and make backup, but then there was to much data, that doing a backup and having windows left like no space.

Its not that much important data tho, just music and family photos... :\

There is this company that i always hear this add on the radio, that say that can recover data, that other companies cant.... but the thing is are they legit and stuff
