I have a netbook with its BIOS flashed and OEM W8.1 key lost. Now Windows (I think the HDD is the same it was on the netbook before flashing BIOS) says the key is wrong or not original/not valid. If I put that key (from the installation on the HDD) back in the BIOS will it recognize it again as a valid key? Or if I copy the oem key from the BIOS of another identical motherboard and put it on this BIOS (just to avoid moving the entire motherboard -and depp understanding how this bios-key stuff works-) will this key be finally recognized has ok?

Thanks Wrong Chip, indeed an excellent video. One request, can you suggest a flashing tool for flashing the new .bin file for Dell? Phoenix SCT Flash for windows (the official flashing tool always throws an error, even with original .hdr file extracted from the original exe file from Dell site). Nothing seem to work. Please help. Thanks
