Install legacy boot in previously installed UEFI

Here's what you can do:

1. Go into BIOS F1 setup -> "Restart" menu tab -> Set "OS Optimized Defaults" to "Disabled.
2. Press F9 to Setup Defaults.
3. Tab over to the "Startup" menu tab and verify the following settings:
- "UEFI/Legacy Boot" set to [Both]
- "UEFI/Legacy Boot Priority" set to [UEFI First]
- "CSM Support" set to [Yes]
4. Press F10 to Save and Exit the BIOS.
5. Boot to the Windows 10 installation media. In my case, I'm using a CD/DVD to USB.
6. Windows 10 should then see your NVMe drive and be able to install the OS cleanly.
