Precision 7865 M2 Flex Bay

Hello everyone,

I've been experiencing NO BOOT DEVICE found on several of my 7865 equipped with a M2 FLEX BAY.

Went through BIOS and FIRMWARE updates and the problem still comes back especially if the system was turned off for some time.

DELL diagnostics reports nothing except no boot device found.  I'm starting to think that these FLEX BAYS are not too reliable.

Has anybody else experienced this type of problem with their systems?

Any input would help.

Thank you.
