That's just the way parted describes things. >> > Model: Generic Flash Disk (scsi) >> > Disk /dev/sda: 124GB >> > Sector size (logical/physical): 2048B/512B >> > Partition Table: mac >> > Disk Flags: >> > >> > Number Start End Size File system Name Flags >> > 1 2048B 6143B 4096B Apple >> > 2 1925kB 2351kB 426kB EFI >> I'm slightly worried by that "Apple" partition on sda - is this a Mac? >No !! I think it is mistake of parted. It is a flash usb key, filled by dd >if=debian-9.1.0-amd64-netinst.iso Really? (checks) Wow, OK - parted is on serious crack there. fdisk is more sane, and on the same image will show: # fdisk -l /dev/sdc Disk /dev/sdc: 30.3 GiB, 32497729536 bytes, 63472128 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x2c869ef3 Device Boot Start End Sectors Size Id Type /dev/sdc1 * 0 593919 593920 290M 0 Empty /dev/sdc2 3760 4591 832 416K ef EFI (FAT-12/16/32) What does fdisk show on sdb for you? >> What do you think an "EFP" is??

Right. Either you're not booted in EFI mode, or /sys is not mounted. Grub is assuming you're on a normal BIOS-boot machine. Make sure that you have /sys mounted, and /dev/sdb1 mounted on /boot/efi, then run # grub-install --target x86_64-efi and see what it does. -- Steve McIntyre, Cambridge, UK. st...@einval.com You raise the blade, you make the change... You re-arrange me 'til I'm sane...
