[Solved} Trick to boot HDD from USB?

[fafler]

Hi. I have a Medion Akoya E5000D touch PC, that was born with Windows 8. For some reason, it won't boot any other OS (tried Debian 9.3, Ubuntu 16.04 and Windows 7) from the HDD. It only want's to boot from a USB drive, if it contains a ISO file (dd if=debian.iso of=/dev/usbdisk) and not if the USB drive contains a normal Debian installation with Grub (drive from my ThinkPad in an USB enclosure). No BIOS settings make any difference.

So, is there a trick to make a bootable ISO, I can write to a USB drive, that just loads Grub from the harddrive, or contains the kernel and initrd or something similar?

Thanks.

Try this command from a Windows Administrator prompt:

Code: Select all

bcdedit /set {bootmgr} path \EFI\debian\grubx64.efi

If that doesn't work then perhaps try http://forums.debian.net/viewtopic.php?p=659660#p659660
