Please note that you have to deactivate Secure Boot for the UEFI boot menu to
start this UEFI shell because it is not signed by Rohde & Schwarz Cybersecurity
GmbH.
If the full-disk encryption has been initialized, the UEFI shell can be loaded with Secure
Boot active. Otherwise, you need to deactivate Secure Boot.
If your UEFI boot menu does not allow starting the UEFI shell, saving the UEFI shell as
bootx64.efi under EFI/Boot and selecting the respective partition in the boot
menu might solve the issue.
Please note that the UEFI shell has to be located on a FAT32 partition.
After starting the UEFI shell, you need to switch to the partition that InstallSBM.efi
is located on with the command fs<X>: (<X> is placeholder for the respective partition
number).
Example:
fs0:
cd EFI/RSCS
InstallSBM.efi --help
