This key changes from PC to PC, it all depends on your PC’s make and model.Typically, you will see a brief note at the bottom or top of the screen indicating what the key is. One such screen is visible to the right, note the legend in the top-right corner indicating F2 will start the BIOS setup and F12 will present the boot selection menu.Some common options include the F2, F8, F12, and Del keys. However, it could be any of the one hundred other keys on your keyboard. Notice the key guide in the top-right corner.Immediately after powering up your PC, as soon as the manufacturer logo (e.g.ĭell, Lenovo, HP, Toshiba, Samsung, ASUS, Acer, Gateway, etc.) shows up on your BIOS splash screen, you will have the option of pressing a special key. On most EFI computers, you’ll need to access EFI setup immediately after turning on your PC in order to see the option of turning on Legacy Boot, usually as an option under the boot options section of the BIOS configuration.

So after convert GPT, should be exit and continue the install. The windows install will format and create all needed partitions. Every thing looks pretty good, in Diskpart its not necessary format or create any partitions. Cross your fingers and hope that this step can be done automatically bootrec /RebuildBcd. Copy EFI bootloader to ESP partition (this is the 'system' or 'efi boot files' partition we created before) i: (where z is the letter of your ESP partition) mkdir EFI cd EFI mkdir Boot mkdir Microsoft cd Microsoft mkdir Boot copy x: Windows Boot EFI bootmgfw.efi i: EFI Microsoft Boot copy x: Windows Boot EFI bootmgfw.efi i: EFI Boot boot圆4.efi Create BCD This step varies quite a bit, depending on your system’s hardware, existing NVRAM (non-volatile memory on your motherboard), and hidden BCD stores scattered around your system’s disks and partitions.
