So I flashed my firmware to the latest F6 revision and everything appeared to be fine, rebooted went into the BIOS and confirmed proper settings and then saved and exited.
No boot into Windows 10, hangs part way through the boot.
I then reset the machine and the same thing so I did a clear CMOS procedure, went into the BIOS and confirmed it was showing the latest BIOS revision and then loaded optimized defaults, same thing.
I had to power off the machine and switch to the BACKUP BIOS which still has the F4 revision, let Windows do the repair thing and then it booted fine.
Anybody else seen this ?
