If your m23 client is using UEFI, you need to create an EFI boot partition first. Position and size of this partition are set automatically and cannot be changed. When there already exists an EFI boot partition on the m23 client, it will continue to be used, keeping the bootloaders of other potential operating systems on the system intact. The EFI partition will only be deleted, created and / or formated, when it is damaged or does not exist.
Format partition
This will format the currently selected partition. Choose the file system you want to use at ”Type” and then click on ”Format”.
