Recuperar boot UEFI Windows

Post by admin » Sat Mar 05, 2022 8:25 pm

Para reestabelecer manualmente (quando a reparação automática do Windows não funciona), após clonagem de discos:

Original: https://answers.microsoft.com/en-us/win ... e572d546df


Windows 10 Installation Media:

Insert the Media (DVD/USB) in your PC and restart.
Boot from the media.
Select Repair Your Computer.

Select Troubleshoot.

Choose Command Prompt from the menu:

Type in the command:

Diskpart

Type in the command:

List disk (Note which disk is your Boot drive number)

Type in the command:

Sel disk n ( n = boot disk index )

Type in the command:

List vol (Note which volume is the "EFI" partition, 100MB )

Type in the command:

Sel vol n ( n = volume index listed above, "EFI", 100MB )

Type in the command:

assign letter=V:

Type in the command:

Exit

Type in the command:

V:

After you have assigned a drive letter Using Diskpart You can format the EFI partition:

Example: if you assigned a letter V to the partition the command would be:

format V: /FS:FAT32

Não necessário: After the format you need to recreate the EFI directory structure with the command:

Não necessário: MD \EFI\Microsoft\Boot

Não necessário: Then change to the Boot directory with:

Não necessário: cd /d V:\EFI\Microsoft\Boot\

Não necessário: Then run:

Não necessário: bootrec /FixBoot

Não necessário: Finally run:

Não necessário: bcdboot c:\Windows /l en-us /s V: /f All

Type in the command:

bcdboot C:\windows /s V: /f UEFI (This replaces the above crossed out lines and works in Win 10 1709)
