I have this problem: some time ago I bought an used fujitsu M470-2 and I try to upgrade to win10.
Something goes wrong and a blue screen of death appear on the display: boot.ini corrupted ecc. ecc.. I try to boot from the cd with a copy of win 7 to repair it but he pc don't read the cd unit on boot. I look in the bios settings to change the behaviour of the machine and see , depressing F1, that the bios is romprotected so i cannot boot from cdrom and recover the machine. I have also another M740-2 with win10 running very fine. Any hint to solve the problem????
