All right! I managed to fix my computer! I've used old Windows 7 installation disc and retried to boot from it until I did it! Then I fixed it using the dvd, now I can start Windows 8. It's not completely fixed (it's slow as hell), but now I can install Windows 8 again!!!

I have another problem. I want to do a fresh install of Windows, and since I have no usable flash drive, and 4,8gb installation won't fit on dvds, I have deleted all Windows except running one. There was installation, but I have overseen the fact that my remaining Windows isn't c:\, but d:\
therefore, since I deleted Windows c:\, I can no longer start windows, or more accurately I can only start Windows and after I log in which takes 15 minutes, I have no interface. I have total 5 processes running. And task manager is like on previous windows...

I just need to get to Windows 8 installation. How?

Got it to start explorer.exe. Could anybody be so kind to post a screenahot of running processes so I could start them manually?

when i try to open computer through 'run' i get:


btw, it's already obvious just by me posting a screenshot that i can run anything through 'run' except:
computer, control panel, disk management,...

also, deskop is empty, and start button is not responding

Gave up... Installing old win7 over everything, then I'll install win8 over win7.

Thread solved

Thanks for anyone helping me.

Mirac if your starting from scratch, listen to Vrosa, and install EasyBCD, once that is installed, you can set up both O/Ses.
