I figured out the issue. On my machine (DEL XPS 13) it was the "Intel
Rapid Boot" option in BIOS. Disabling that resolved all my boot issues.
I can now boot with MBR or GPT off the internal SSD. And, I can also
access the BIOS with the internal SSD installed in the system (this was
not possible before)
Ooouuhh ... Intel Rapid Start still messing up machines?
There was a well-publicised series of problems with a number of
ThinkPad models (T440p and many relatives) around the end of 2013 /
early 2014. If I recall correctly, one needed to turn off some sort of
UEFI mode (which disabled Intel Rapid Start at the same time) to
prevent bricking the mainboard when installing OSs which were not
sufficiently micro and soft. Seemed that the "feature" would read some
data from a particular area of the harddisk, expecting that "the right
data"(tm) would be there (why verify input, right?), and then just
flash it to NVRAM.
I'm aware your problem may be related to a different phenomenon. Just
meaning to say: Lenovo (and probably other large vendors as well)
released BIOS updates during 2014 to fix some rather nasty Intel Rapid
Start issues, so in case your machine is of sufficient age, you might
like to look into this.
Hope it helps ...
