Hi all . I installed windows 8 . No errors during process but after first restart pc remain on motherboard logo and nothing happen . I can't enter in bios , i can't do nothing . The only way to enter in bios is remove the hard disk where is installed windows 8 . My hd is sata . I don't know what can i do , i'm without os on my pc . Ps. First to install windows 8 i tried to scan my pc with windows upgrade assistant and all was compatible except two programs . Thanks .
