I recently encountered a problem with my OS, leading me to attempt a fresh install of Windows. My previous windows versionn was 7 Ultimate, I am now attempting to boot a copy of a Windows 10 ISO on a USB Flash Drive.
The problem is that despite selecting the flash drive as 1st in boot priority through bios, the system is still booting from the HDD. I have already tried removing the HDD from the boot queue altogether, leading me to a screen which reads: "Reboot and select proper boot device or insert boot media in slected boot device and press a key". Upon pressing a key the same prompt is issued.
Rig is as follows:
Intel i3 Processor (Sandybridge)
Nvidia 570 GPU
Hyperx 2 x 4gb sticks.
