I am completely at the end of my tether with this system. I have a Samsung NP370R5E-A05UK laptop, 14 months into owning it, it was slowing down, so I thought I'd re-install the OS. It is a Windows 8 machine, but I wanted to install Windows 7 on it. First, I created a bootable USB with Win 7 installation files (I've used this on another PC a week ago so I know it works). It simply would NOT see the USB while booting no matter what I tried. The BIOS has NO option for Boot From USB/CD etc., only "Boot Option 1: Windows Boot manager" or whatever it's called. So I can't set the boot priority to anything else on since there's only 1 option - FastBoot is also Disabled. I went into Windows 8 settings and tried the "Recovery" options - "boot to UEFI BIOS" gets me to an old Blue-background legacy BIOS, not a UEFI one. There's no option to boot from USB either. Or CD. So I figured I had no choice but to restore Windows 8 from the Factory install partition. That worked fine, until I tried updating Windows 8. It got stuck on 0%. So I manually installed updates - they worked until I rebooted, and found the "Failure Configuring Windows updates - Reverting Changes" screen. That screen has been going for hours now and I can't get past it. I can't boot from external devices. I can't bloody well do anything with this POS. Does anyone have ANY idea what I should do from here???
