MSI bios help - NVMe problem

[shadowscotland]

Just setting up my X570 gaming plus and it will not boot from my xpg sx8200 pro (fresh install of Windows done by previous owner)

It's named and selected first in boot order but
'not present' in the storage tab (no drives are)

Tried both ports, 'not present' shows when installed in both.

Passes NVMe self test without issue.

First time using M.2, not enjoying the hassle or silly small screws (but that's me getting old hahaha)

A quick Google showed I'm not alone, but most have drives recognise in storage but not in boot order. Where as my issue is the reverse.

Would appreciate a bit of help if you have an MSI board

Try a more recent bios?

It was working for Windows to be installed and benchmarked before being sent to me.

Bios's don't just stop recognising drives when you remove hardware for transportation.
Or is that a thing with m.2 and I'm just used to sata SSD's being hot swap able.

It must be a bios settings I'm missing,
So you set the NVMe to 1st in boot order but need to tell the board to be in 'm.2 mode' like an Asus bios.

If the drive was formated and windows installed as GPT then you need to enable UEFI and disable CSM for windows to boot, if the drive was formated MBR then you need to enable CSM for windows to boot and disable UEFI. These are options in the BIOS.

Enabling UEFI removes all trace of the NVMe from bios except the SSD self test.
Not showing in boot order,

Enabling CSM removes all trace now too.
Doesn't even show in the fixed boot order priorities which it did before.
SSD self test still correctly shows drive.

Rebooting fails to post
Entering bios (CSM)
Boot mode selected (legacy+UEFI)
now shows the NVMe (hard drive icon, red in colour no 'u' above it)
And correctly named in fixed boot order.
Moved to 1st position (it's the only drive in the system)
Still not showing in the storage tab of EZ mode (AHCI mode)
Save and exit, reboot
'Reboot and select proper boot device or insert...' error message.

Problem solved,
Previous owner deleted the fresh install of windows I paid for and only just told me after being afk for a few day...

Really appreciate the help purgatory.
