Hi everybody,
I have a Samsung Ultrabook, approx. 2 years old on which I installed ubunt a while ago.
The Ultrabook comes with one of these Non-UEFI-Secure-Boot-but-still-EFI EFIs capable of emulating a Legacy PC Bios.
Originally I installed Ubuntu using the Legacy Bios method and Grub-Bios bootloader.
Some weeks ago I decided for any reason I cannot recall now, I would like to switch off the Legacy Bios and Boot using the EFI firmware.
Conversion from MBR to GPT went ok, and Grub installed smoothly. However, I am encountering a strange issue I have no explanation for.
When I power up the Ultrabook, I am immediately presented with the "grub cannot find partition ..:", "grub rescue>" shell.
The UUID it prints out does not match any of the partitions of that system.
The workaround to this is to press the shortcut to fire up the EFI/Bios emulation menu, then exiting the menu again immediately, and voila:
it boots!
However I'd preferr rather not to use this ridiculous "Hack" to start my system.
Any ideas, how to fix this?
Thanks!
