Mount EFI Partition

By default you cannot access the EFI partition on a Windows PC. If you want to be able to verify that it has the correct files you will need to mount it first. Note the EFI partition is a FAT32 file system.

Open an elevated command prompt and type the following commands:

  • diskpart
  • list partition
  • select partition x: (x is the EFI partition)
  • assign letter=b (b is used as an example as it is often not in use)
  • exit

  • You will still not be able to see the EFI partition as you need to kill the explorer process and start it with administrative privileges.

  • taskkill /im
  • explorer.exe /f
