![]() You should not type the "Shell>" before entering each command. I am going to show the "Shell>" prompt before any shell commands. There is usually no script file, so it is usually not necessary to press ESC. You can press the ESC key to prevent the execution of the script, or wait for the "Shell>" prompt. The UEFI Shell will run a "startup.nsh" script file if there is one. You can get the list again at any time using the "map" command in the shell. You will also see a list of the filesystem and block devices and the mapped (associated) ACPI (Advanced Configuration and Power Management Interface) device names. Other boot media may immediately start the UEFI SHell, or display some other kind of boot menu.Īfter you boot the UEFI Shell, you will see information about the shell, and the "Shell>" prompt. With rEFInd you will see a graphical menu, and one choice is to start the UEFI Shell. Your boot media should have an EFI System Partition containing at least the file "\EFI\BOOT\BOOTX64.EFI". You may have to change the UEFI settings to enable booting from the dvice, or change the priority of boot devices. To boot from the CD/DVD or thumb drive, you will usually need to press a hot key as your UEFI firmware is starting up the system. If you want to create a boot CD/DVD or USB thumb drive with the UEFI Shell, follow the instructions on the rEFInd web site, or read my post explaining how to create a thumb drive with the UEFI Shell. Along with rEFInd there are UEFI drivers for filesystems like ISO and ext4 that may or may not be included in your system's UEFI firmware. Don't download the ZIP archive because it doesn't have the UEFI Shell. It has an ISO image and a USB Flash image that you can write directly to the medium that you will boot. You can get the UEFI Shell from a few different places, but I recommend downloading the shell along with the rEFInd boot menu software. The UEFI Shell is part of the virtual firmware. Or, only connect disks that have no EFI System Partitions that can be booted. Press the ESC key immediately when the virtual machine starts to get into the UEFI Shell. Select the option to "Enable EFI" for a virtual machine. You can experiment with the UEFI Shell using the VirtualBox virtual machine software. So, first you have to create a thumb drive, CD or DVD that can boot into the UEFI Shell as a default boot option. Obviously, if you're installing the shell, it isn't in your boot menu. On other systems you have to copy the UEFI shell executable file to your EFI System Partition and then boot it. So, how do you boot into a UEFI Shell? Some UEFI firmware comes with a UEFI Shell and has a boot entry or hot key to boot into the shell. The only concern is to make sure that your UEFI Shell is the same version, or close to the UEFI firmware. Most of the commands use required UEFI system functions, so they generally all work. ![]() A UEFI Shell has a standard set of commands defined by the UEFI specification. One answer to the problem is to boot into a UEFI Shell (UEFI text command console) so that you can enter commands to manage boot entries. Ubuntu and other Linux distros will usually add their boot entries.īut, what do you do if you want to add your own, and your motherboard provides no way to easily add boot entries? The MSI Creator X288 that I have is like that. Windows will add its own and make it the default, sometimes even if you don't want that. One of the more frustrating things about UEFI is that every implementation has different support for creating and managing the firmware boot entries. ![]()
