restore default settings for Motherboard gigabyte p85 d3

that would have been the bios, it likely changed the boot order, could be why windows wasn't working

In the BIOS features tab on advanced view in bios, what does it show under WIndows 8 features?
It is possible its swapped you to other OS since its the default and it is using the wrong boot method

Windows 8 Features

Do you have a win 10 installer?
if not, On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB

need to figure out what format your drives are
Boot from installer
On screen after language choice, pick repair pc, not install
Pick troubleshoot
Pick advanced
Pick Command Prompt
Type diskpart and press enter
Type list disk and press enter

there is a column on far right called GPT.
If your boot drive shows an * under the GPT column it is GPT,
If it doesn't show an asterix, it is not GPT

if your boot drive is GPT, the boot options in those menus should be
CSM support - never Disables UEFI CSM and supports UEFI BIOS boot process only.
Boot Mode Selection - UEFI only Allows booting from operating systems that only support UEFI option ROM.

If Boot drive isn't GPT
Always Enables UEFI CSM. (Default)

Boot Mode Selection - UEFI and Legacy Allows booting from operating systems that support legacy option ROM or UEFI
option ROM. (Default)
Or
Legacy only Allows booting from operating systems that only support legacy option ROM.

Legacy could be either of those, default explains why it swapped on restart.

I suspect you have GPT.
