Question Boot drive option missing in bios.

[instawookie]

Just finished a MB swap a few days ago, z690 to z790 and for the most part everything has went smooth. However I noticed I don't have a boot option in bios. Currently its not causing an issue I'm booting into windows just fine, Windows has been activated too the new MB etc.. . Will this be an issue later down the line? is an easy solution removing my m.2s and ssd's and doing a windows reinstall? Sifted a few reddit threads and they say easy fix is a 20 min windows bootable usb drive, just not sure how true that is.

Did you reinstall the OS after the motherboard swap?

I did not, got alot of mixed reviews on that. Some said not needed, others said I got too do that. Also attaching a link of my hard drive set ups if that helps. https://ibb.co/gdskfhc

Your first order of business is to disconnect all drives, besides the one you intend to have the OS on, then reinstall your OS after fabricating your bootable USB installer for the OS.

I figured that would be the easiest solution, saw some other options utilizing windows cmd prompts but that looks less fun.

Actually, while this is a good recommendation, it really shouldn't have anything to do with what boot options are available in the BIOS. If Windows is installed, then there should be options for, at minimum, Windows boot loader, and often, Windows boot loader AND/OR the drive letter of the drive with Windows installed on it, depending on the Windows version and the type of installation that was done.

First thing I would do is make sure you have the latest BIOS version installed according to what is shown on the product page for your motherboard. And, it IS a very good idea that you back up anything important from Windows that you don't already have backed up elsewhere, disconnect ALL drives except the drive you are installing Windows FROM and the drive you are installing Windows TO, and do a clean install. What version of Windows are you running?
