Question PC keeps booting to windows after new Mobo and CPU

[Sylkesh]

I just got a new motherboard and CPU(Asus z590 plus, i5-11600k) and after having everything connected is just keeps booting to bios. It shows that my ssd's are there in storage information, but it shows no bootable drives. There is most definitely information and windows on one of the SSD's so I'm not sure if I'm plugging them in wrong or what.

The backstory on this?

New motherboard and old drive+OS?
That often fails.
With a new motherboard, a clean OS install is strongly recommended, usually required.

Reduce the drives down to JUST the OS drive.
What happens?

Solved it myself! Changed from UEFI only in bios boot to legacy
