After installing debian on usb,
I must choose between grub-install --removable or --force-extra-removable
Which one is best?
they say it installs in BOOTX.EFI.
this is the one that is autodetected by the bios when connecting the USB. But it does not boot even if either --removable or --force-extra-removable was used.
And I did not forget to use update-grub.
it picks /EFI/boot/BOOTX.EFI
And during the startup it gives the error below before rebooting
System BootOrder not found.
So manually, I have to pick /EFI/boot/grubx64.efi, and it works.
---------> Can I remove all the stuff in /EFI/boot except the grub.cfg and grubx64.efi?
Then perhaps the bios can only detect the one that works.
