I'm desperate. After upgrade of my Windows 8.1 to Windows 10 it failed in process of installing software in new clean Windows 10. So, I deleted upgraded Windows 10 partition for clean install of Windows 8.1. And problems began:
I used all usable removable media except ZIP, so DVD, USB, SD and CF cards and each medium looks like error in data. It's mysterious - I can't have each USB port, card reader and 4 used DVD drives broken, also media incorrectly written. When I begin install of 8.1 it fails with report that cannot find license terms, other media fails and reboot at install boot, in all cases = not possible install <any> OS - I tried also Linux Mint 10 (Commodore OS Vision) - each try failed. What did Windows 10 with my PC? I can boot only live DVD @ctive Boot Disk, not more - it's near week of trying - I used 3 USBs, each port, 4 microSD cards, 1 CF card, 5 DVD disks with same copies, 4 DVD drives - Windows 10 destroyed my PC? If, I hate it, if not I try to use first on virtual machine - final upgrade with all changes like real PC - but only if I will have any chance to install <any> OS.
Can anybody explain me my situation?
Thank you very much.
