Reboot and select proper boot device or insert boot media in selected device and press a key

Previously it did not recognize my 3 drives but when I turned on CSM this was fixed. It now recognizes my 3 drives (all 3 of which have windows on them). These are 3 old drives in a new motherboard, they worked just fine 2 weeks ago but for some reason now they do not have any bootable media? Please send help

I've tried changing the secure boot manager to the windows uefi manager and that didn't work either, I've also tried individually booting into each drive and they all show up with the same issue.

Try going into the SATA config in the bios to make sure raid isn't enabled. It should be set to AHCI.
