Hi installing new windows 8 system even without access to the bios and no device able to boot test on laptop in UEFI I could not boot from any device since the bios had a pass word even making bios reset under the memory even a usb floppy drive the diskdur had no system and impossible to find the password bios I saw lots of tutorial on the net but nothing worked but I found my solution to reinstall windows 8 and it can be used for all other portable ..... here is my solution: we need another mobile X windows 8 and a USB key and cd windows 8 (or key bootable Windows 8) 1 _ create a recovery drive on the USB key using the mobile X 2 _ diskdur remove the Acer V3-771G and put it in the portable X 3 _ start with the recovery key 4 _ using the command prompt 5 _ convert gpt with dispart: make a clean and then convert gpt do a primary partition and name the letter of the partition C format the primary partition fs = ntfs 6 _ put the diskdur in portable V3-771G and key recovery cd and windows 8 7 _ in command prompt type the letter of the CD player and make setup ok !!!

I have done this before handling I know this does not work there is always the word pass bios but I have at least install the system I do with linux virtual or other cmospwd if I can blow this pass I look cmospwd 64 bits to access the bios and skip this pass , but can not be installed on Windows 8 64Bit cmospwd perhaps with the key récuparation cmospwd should work
