I have a Toshiba Satellite L50-A1-D6 with the latest (14 November 2014) BIOS update. I have removed Windows 8, completely formatted the HDD (in GPT), and installed Linux (Ubuntu, but this is not really important).
If I keep my laptop in UEFI mode it acts weirdly:
- The laptop boots correctly into Linux, but when I shutdown, it refuses to boot again (at boot it shows a "no bootable media found" error).
- So I booted up from a live USB, reinstalled GRUB and I can boot the computer normally -- but just ONCE!
Actually, before shutting down my computer I have to reinstall GRUB in the "fake MBR" every time! If I reinstall everything goes well... If I forget to reinstall, the computer refuses to boot.
It seems that my computer erases the fake MBR every time I boot.
Is there a solution? A workaround or similar?
