It appears the drive isn't visible in the Disk Manager within Windows.
Sure, that sounds frustrating. It seems like the BIOS isn't accepting the update. You might need to try using a different USB port or check if the flash drive is properly seated. If that doesn't work, swapping it out for a newer drive could be the solution.
nvme needs to work backward for the gen3 controller, but it won’t run gen4 speeds. Make sure your BIOS uses a fat32 formatted USB. The file name should be up to 7 characters at the start and 3 at the end, like 1234567.xxx. Some BIOS systems can’t handle longer filenames.
Right-click the USB stick, then Properties, and choose Format. Select the appropriate type and pick fat32.
I updated the BIOS and... nothing altered. The NVMe setup remains unchanged and the M.2 SSD isn't recognized. I'll attach images of the three key BIOS menus, since the others aren't connected to SSDs or the BIOS. As you can see, it's already configured in AHCl mode.
I'll look at the chipset section to see what's causing the issue.
