I'm at my wits end here. I suppose it is not a certainty that this is a Mobo issue, but it certainly seems like it. Just to kick it off, here's as much detail as I can give regarding what I am working with:
Board: MAG X670E Tomahawk WiFI
BIOS version: 7E12v1G
OS: Windows 10 (I was bottlenecked by my old CPU)
CPU: AMD Ryzen 9900X Granite Ridge AM5 4.4 GHz 12-core
RAM: 2x Corsair Vengeance RGB DDR5-6000 PC5-48000 Dual Channel
PSU: G.Skill 850 80W Plus Gold ATX, fully modular
GPU: ASUS TUF Gaming RTX 4070 TI Super (16GB VRAM, I think), but I have also been using the integrated graphics to test these things because having to take this card in and out of the chassis constantly is a bitch and seems risky
"New Drive": Samsung 990 Evo 2TB NvME 2.0 SSD PCIe 4.0 x4/5.0 x2 M.2 2280
"Old Drive": WD Blue 3D NAND 250GB PC SSD - SATA III 6 Gb/s M.2 2280
"External SSD": There is also an external SSD a friend let me borrow for troubleshooting, not sure of the model, but it is loaded with Windows 11, I think
So a little while ago, I got the "New Drive", cloned my "Old Drive" onto it using DiskGenius, and then installed the New Drive. Suddenly, my PC stopped Posting at all. After some troubleshooting, I replaced my mobo/RAM/CPU with what you see above. It Posted, however, the machine will absolutely not boot off of the New Drive. I've tried it in M2 slot 4 and slot 1 to no avail. However, it does recognize the New Drive in BIOS as a storage device.
My next move was to put in the Old Drive and attempt to boot from there. The machine now does not even recognize the Old Drive's existence, regardless of slot. Does not boot from it, will not recognize it as a storage device. So I tried the External SSD, plugged in via USB, and it boots off that device. I did this again with the New Drive installed, and I can access the New Drive, it just won't boot from it. The Old Drive remains undetected. I even tried putting the Old Drive in an external enclosure and connecting it via USB, and that doesn't work, either. Undetected.
When I'm in the MSI BIOS with the New Drive slotted in (regardless of slot) I can see it as a storage device. What I don't see is any option to put it in the Boot order. This may not be an issue, but it doesn't seem like the option to boot from an SSD even exists (perhaps that's just not how it's labeled). When I have tested this, I have no other drives installed.
I'm running out of ideas. I suppose the only thing left I could do is reformat and re-copy the New Drive and/or flash an older BIOS to the board, but I am hoping someone, somewhere in here has run into this issue before and has a solve. Ideally, I would have the New Drive in slot 1 and boot from it, with the Old Drive in a different slot or available as an external for extra storage. Thanks in advance, and sorry for the long post.
