Can't install windows after linux

I've got an uefi based system with linux on it I deleted the win 7 partition to install win 8 because the installation failed when it was running on windows

when i try to install windows 8 from usb i get the message "Windows installation encountered an unexpected error. Verify that the installation sources are accessible, and restart the installation. Error Code: 0xC0000005" I mention that installer detects my usb stick

And when i try now to reinstall windows 7 i get "Windows could not prepare the computer to boot into the next phase of installation..."

Is there any chance to install win 8 without erasing all hard disk? Any help is apreciated, thanks!
