So I have an Acer Aspire V5-131 and long story short (really, it's a long story!), I decided to do a complete wipe of the HDD (using dban). So right now the HDD is absolutely wiped, there's nothing on it. My plan was to basically then install Windows 8.1, and I created a bootable USB for it using Rufus following these instructions. Turns out, if I reboot my laptop and have that USB drive plugged in, the laptop keeps repeatedly rebooting, i.e it'll boot showing the Acer boot screen and then it'll just restart and display the boot screen again. And it does this repeatedly and never stops. Now, if I take the USB out and reboot, the problem stops.
I've been into the BIOS and have disabled secure boot, and I've changed the boot order so that USB devices have priority (I say "USB devices" since oddly enough, the boot priority order has "USB HDD", "USB CDROM", and "USB FDD") and the problem still occurs.
Interesting note though - yesterday, when my laptop was still on Ubuntu, I managed to create a bootable Windows 8 USB through the WinUSB utility but that only worked if I changed the boot mode to "Legacy BIOS". The current bootable USB I have at the moment (that I made with Rufus) won't work whether the boot mode is UEFI or Legacy BIOS.
I admit my knowledge of UEFI is severely limited but the main question is, why am I not able to install Windows when the boot order is UEFI (as I said, the laptop keeps rebooting)? Thanks very much in advance.
