Bad UEFI implementation Workaround

I decided to install the latest stable branch of Debian Stretch on a budget laptop (Toshiba Satellite C50-B-14D) bought in 2015. Its minimal specs was perfect for Linux. Installation image used was debian-9.0.0-amd64-netinst.iso. Once the installation process finished and I restarted my system, it would not recognise grub or any boot partition.


Rename folder and filename /EFI/debian/grubx64.efi to /EFI/boot/bootx64.efi

With a different filename the UEFI implementation recognised and booted successfully. This might not work on all manunfacturers.
