@jerovsek - Thanks from me too.

I have always disabled any "fast boot" mode on my laptops over the years, because the pre-boot time was too short to allow me to press a key to go into BIOS setup or choose a different boot device - so I've never noticed the side-effect described in the article that (at least on some laptops like the Samsung) this mode prevents changing the boot device too!
@pclab - Thanks for your earlier reply. Hopefully the info in that blog linked by
jerovsek will allow you to change the BIOS boot device, if you want to boot from Linux to see if the SSD is readable, while you are waiting for your adapter.

@northwind - Thanks for explaining the part which I didn't understand earlier.

That's another beer I owe you ...
