Fabric restore problems

hey,

I was trying to restore my pc, this did not work but after a few times it did work.
Now i can not start my pc, I get the error that a certain file is missing.
I also can not restore him anymore, I get the error that a partion is missing.
Can anyone help me? I am sorry for my english, i'm a non native english speaker!

greets

Is this a OEM manufacturer's PC with Pre-installed Windows 8?
Which as been updated to Windows 8.1?

I configurated the pc myself, and installed windows myself. I'm not sure if it is windows 8 or 8.1.
It was my sister's pc so i'm not sure if it is updated or not but i'll ask. Is there a way to check this when i can not start him up?
Thanks for the reply
