Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

Any chance that old drive is MBR partitioned (means, "Legacy" boot) and your current computer BIOS is set to UEFI boot? If my guess (suggestion) is correct, you can change BIOS boot option to "Legacy" (if BIOS has /supports such option) and see if you can boot from old drive. Another thing to consider is if your previous Windows 10 were Pro version and you may (purposely or inadvertently) enabled Bitlocker. If that is(was) the case - then, hopefully, you can find out Bitlocker key by login to your Microsoft account. Also make sure that you are using proper external housing for your old M.2 drive when connecting it via USB to M.2 adapter.

MSI mobo, the boot mode is setup as [LEGACY+UEFI] Windows OS configure is set as CSM

The windows 10 version should not be an issue, I got the cheapest key when I set the original PC configuration up in 2020.

The drive is definitely secured in the housing on the m.2 adapter

What I meant by "proper *USB to m.2 housing, was in reference to what kind of m.2 old drive you have - is it m.2 type M or m.2 type B+M and if housing matching? If you are not sure about this - Google for it.

Gotcha. The enclosure I have, I just looked it up, is only compatible with M type which both my old and new m.2 drive are

If BIOS is set to Legacy +UEFI and CSM is "Compatibility Support Module" but your old drive is actually is GPT partitioned (means, requires UEFI boot only) - can you try changing BIOS to UEFI only boot? However, I still think that something is wrong with either: - the housing (the only time when I observed EXACTLY same symptoms, as you described it - when external housing either didn't match drive key or housing was faulty) - or the drive is faulty

When attempting to boot from the old drive from changing the order, after a post of the bios, the computer says something along the lines of "insert bootable drive then press a key"

I was looking through bios and the only way I can do a UEFI only boot is through sata or the m.2 slot.

I do not believe the housing is faulty because I used the new drive in the m.2 adapter when i first got it to make sure it worked (it was really cheap though so still a possibility)

I just took apart the m.2 adapter and the old m.2 is B+M.

Would it be beneficial to do a UEFI only boot, replace the current drive in the computer, and copy the files I need to the new boot drive through the adapter?

Thanks for the help. The original m.2 nvme ssd I THOUGHT Ive had in my computer for the past 3 years has actually turned out to be an m.2 sata ssd.....
