Windows 10: PC won't boot

I have a Dell XPS 8700.

recently, while writing an email the PC crashed with a 0xc000021a error. In the days since and many trips to the internet, I have gone from that to the point where now when I boot it says "NO BOOT DEVICE FOUND"


i'm running now from a USB harddrive with Windows10. It is in a 'Windows to go mode'.

Anyone have an idea?

My pc won´t boot Windows 10 from USB/DVD

So I wanted to change from my Windows 10 x32 bits to 64x. I downloaded the Mediacreationtool and used it in both a USB and a DVD. Tried used the usb, the disk and both at the same time but they won´t boot.

I have a P7H55-M motherboard, the BIOS is updated and configured to boot first DVD, second usb and third SATA.

So if someone could help me it´d be great.
