Bootable USB not detetcted (solved)

[longy35]

Hi,

Have just build new System and got into bios fine, when installed a genuine Windows 10 install media USB stick into the IO the bios does not detect it at all. Have checked the format of said media is FAT32, detects another USB I had on hand. 

Specs:

AS rock B650 Pro RS

AMD Ryzen 5 7600

Kingston Fury DDR5 5600Mts

Samsung SSD 950 Pro nvme m.2

RTX 3080

Cooler master v1000

 

NOTE I only have a Mac (my wife's) to do any troubleshooting or created other media on.

Is that still a Windows 10 install USB Key?

Like, yes that's what MS ships physical copies as, but they're not write protected.  Someone could have formatted it and turned it into a vanilla flash drive for data storage.  It would need to be reimaged with the bootable installer in that scenario.

Yes, it is. Has been in my possession since new. Have kept it as a bootable USB.

Turns out I needed to change from Uefi to legacy in boot tab in bios.

Everything I read online told me not to do that, anyway. I sorted it. 

Thanks for the reply, appreciate you taking the time.
