Question New motherboard/CPU no bootable device in bios

[ASaucyNative]

My previous motherboard crashed, and I recently purchased a new one along with a new CPU. I installed a new hardware and attempted to boot up my PC but in the bios of the new motherboard it says there are no bootable devices. As far as I can tell there are no issues with any of the hard drives I using this PC, and I'm able to see all the drives in the storage configuration on the BIOS. I assume I will need to do a clean install of Windows, but I was wondering if there is any way I can save any of the existing data on the hard drives.. thanks in advance for your help.

To start, you need to disconnect ALL drives except the one you want for the OS.
