Hello, I would like to know how to enter the EFI Shell. After this, I would like to know also what is the command to "boot" partition with Windows 8.1 (not installation, but boot to install) Regards.
You need to find out where it is mapped, like FS0: etc, you will see it in the shell. Then for example you have to type FS0: and when it switches to FS0: type dir to see that you are on the right location, and then navigate to the folder where the .efi file is with CD command, cd EFI, cd BOOT etc, and then just start the efi file by typing the file name. It has to be a FAT32 partition.
At the EFI Shell I get: fs0 (USB) fs1 (HDD) fs2 (HDD). I BELIEVE that my HDD is fs2, but right then goes BLK8 ... this is? this indicates the partition? I need to know how to identify the partition Z: in the EFI Shell.
so try them all until you find it. Type fs1:, then dir fs2:, then dir and you will find which of them has the file you need.
