[SOLVED] SSD drive detected by BIOS, but not Windows setup during install from USB

[JasonLS]

I have attempted to install both Windows 10 and 11 from a USB to a newly assembled desktop. The motherboard is an ASUS Prime B660-PLUS D4 LGA 1700 ATX, and the CPU is an Intel Core i7-12700F 4.5 GHz. The drive I am trying to install to is a SanDisk SSD PLUS 2TB Internal SSD - SATA III. When I go into the BIOs I can see the drive, but when I run Windows setup for both 10 and 11, the drive is not shown. I spoke to ASUS customer service, and we checked the BIOS settings, they were already properly set up according to tech support. The settings checked are below:

Launch CSM: Enabled

Boot Device Control: UEFI and Legacy OPROM

Network devices: Legacy only

Storage Devices: Legacy only

Boot from PCI-E/PCI Expansion Devices: Legacy only

I tried changing the settings to UEFI and Ignore with no success. Is there something I am missing?

Is the SanDisk M.2 format or 2.5" format?

If the ssd was previously used there may be some hidden partitions on it that need to be cleared out before a new installation. The ssd may also have an MBR partition identifier and windows now prefers GPT for use with Secure Boot. You can use any usb bootable partitioning tool like Gparted to examine your ssd, remove any old partitions so that the space is totally unallocated and check to make sure there is a GPT identifier or create a new one.

If it is not seen during the Windows install, that is a different issue than whatever partitions may exist on it.

Make sure sata controller mode is set to AHCI (not Intel RST with Optane).
Also disable secure boot.
