[SOLVED] Switched MB & CPU, BIOS won't recognize boot drive as a bootable drive

Long story short, upgraded my CPU and consequentially my MB (New socket) and although it's posting fine and is going into the BIOS just fine it will only see a left-over ubuntu install and a windows boot manager (On the same HDD). It also sees my USB Drive with the newest Windows 10 ISO. The BIOS shows all components and all drives working, and I've read somewhere that Windows doesn't like MB swaps, what can I do? I don't want to lose any data. P3 is what my C: drive used to be.

I have a z590 gaming x MB with the latest BIOS, under Boot there is an option to Enable/Disable CSM Support, it is set to Disabled by default, should I enable it?
Yes, set CSM to enabled and then try to boot up again. Let me know if it works or not.

Are you able to change the UEFI settings to CSM (Compatibility Support Module) or legacy BIOS?

Sorry for the long reply, I turned it on and it showed up, and booted into a drive repair mode, then it restarted itself and everything is how I left it, thank you very much! :D
