NUC Install Issues - nvme pcie drive

[Wirezfree]

So the story do far,

The "NVME" version of the drive was a "no go", friend returned it and got the "AHCI" version, and "Oh NO", this did not work.
At this stage I'm thinking could it possibly be a hardware issue with the M.2 slot on the motherboard..??
So there was one last option, use an M.2 version of a SATA SSD, so I got got one, on a return basis from a local supplier.

Guess what, It also would not work  At this point, it really did look like it was a Hardware issue,

I had one last Google around, and found what was exactly the same issue on the Intel Site,
NUC5i7 trying to install in Legacy Mode, posted 21st Nov.
Quickly read down the thread, the poster tried an older BIOS, and it worked.

I quickly downloaded the older BIOS and flashed the NUC.........
I booted Win7 installer from USB stick, and guess what, I also could install Win7
I then booted my LL USB installer, installed that, and guess what, It ran

So the NUC is now dual booting Win7 & LL2.6 on the M.2 SATA SSD.

Then on the above Intel Thread, an Intel person posted on the 24th Nov.

This issue has been reproduced and the engineering team is working on a fix. For now go back to the earlier BIOS. Thank you for all the information.

So what next..??,
Do I now take a chance on trying it again on the AHCI version,
I can see on the original posters screen shot the model number is the AHCI version, so it should work.?, I've posted the question on the thread.

Also, my friend wanted Linux Mint,
Not sure how to add that now, given I put LL on it first in my rush to see if it would work

So the moral of this story,
Don't give up, and don't assume the latest BIOS is always good ..!!!
