Not detecting windows post BIOS update

[SirobLeRoi]

 

I have recently put together my first build complete with x570 ROG-F and was in the process of making sure everything driver and BIOS wise is up to date. Updated the bios to most recent version seemingly without issue but now windows is not detected on the system.

 

Posts fine and can enter the UEFI fine and my M.2 and SSD are visible but not recognised as boot drives. Windows has been booting fine from the m.2 fine since the build on Saturday.

 

Have not changed anything in the UEFI but did try to reset to default just in case. Any help would be much appreciated

Its probably trying to boot from M.2 Legacy
if thats the case: in your boot options youll see something like...
- M.2 SSD Disk 1
- M.2 SSD Windows 10... Boot/startup/Loader or something ( i forget exactly)

The EFI will have a name "Wondows Menu" or something.
Should boot then - Just make sure you set your Compatibility to
1. EFI+Legacy,
and
2. boot from UEFI first.
