Well, since I never see the loader= screen as we are used to, were is that gone? There are no boot options anymore (like sin= gle user mode, ACPI off et cetera). Is this intended? Besides, checking both boot1.efi and loader.efi with file() shows something= like loader.efi: PE32+ executable (EFI application) x86-64 (stripped to external= PDB), for MS Windows. So both are PECOFF format files? >=20 > boot1.efifat is a FAT filesystem image that contains a copy of > boot1.efi as /EFI/BOOT/BOOTX64.EFI.

The partition created by the install= es with type "efi" is then the /EFI/ partition, which then contains a folder BOOT and in= which the boot1.efi is located?=20 As I understand, I can manually mount this partition as FAT and copy boot1.= efi as BOOTX64.EFI into it?
