You need to put the Shell.efi or Shellx64.efi file into the \EFI\BOOT\ folder on the FAT32 formatted USB, and rename it to BOOTX64.EFI ??that's the default name UEFI looks for when booting.]]> Tue, 10 Jun 2025 15:24:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=10481&PID=195819&title=how-to-launch-efi-shell#195819 https://forum.asrock.com/forum_posts.asp?TID=10481&PID=195405&title=how-to-launch-efi-shell#195405 Author: RokeJulianLockhart

Hi publius21

I am having the same problem. Always not found. Could you tell me where you got the Shell.efi and where you put it exactly? And USB stick is still FAT32 formatted? Any other things?

Never mind -- it was something stupid. Something really stupid. On that Github EDK2 folder tree, I ended up downloading an HTML file, which did the actual download, not the file.

   Anyway, I've got the correct shell binary and it works like a charm. ]]> Sat, 22 Dec 2018 18:03:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=10481&PID=59156&title=how-to-launch-efi-shell#59156 https://forum.asrock.com/forum_posts.asp?TID=10481&PID=59140&title=how-to-launch-efi-shell#59140 Author: publius21

    I've got a Taichi z390 Ultimate, and I'm trying to use the "launch EFI shell from filesystem device" option, but I can't get it to work. Always, "Not Found". I've put the shell I downloaded from the EDK2 in the root of the EFI system partition, named it both "Shell.efi" and "Shellx64.efi", then copied it to the \EFI directory as well as EFI\Boot.

    Also, I've put in on the root of a FAT32 formatted USB stick under both names. No matter what, "Not Found" is always the result.
