I was trying to install windows 8 on an old computer, a dell dimension 2200 to be exact, and everything seemed to be going fine, so I left, but when I came back, there was a screen saying the installation failed. The file was causing problems was MegaSR.sys, and the error code or "status" was 0xc0000221. Then when i tried to boot from a different Windows 8 disk, when I select CD drive in the BIOS menu, it just goes back to the error screen. I tried booting into safe mode, it didn't work.
What can I do? My PC is essentially bricked. :'-(

hi,

Overwriting your HDD is available! And after the install, you should make sure you have it set to boot first fom the CD/DVD-ROM in the BIOS correct way!
