Okay so i first tried " Other options " , ive tried like all of them. and this happens every time.

It comes to the loading sign, then , i get a quik blue screen with loads of letters on it (too fast to read, like a split second). Then RESTARTS....
Ive tried this so many times, it does the same thing.

Then i decided, to try Option 1-3.

I boot from cd, and click repair.


Now, i come to this....



Except for me.... it doesnt show any operation system. And i do not know how to load drivers? can anyone help me?.


.....

Also, if i click next.
This comes up.



.... ive tried all of then, they all dont work. (im guessing this is because i havnt picked a operating system yet)


My pc has alot of important stuff on it, is there anyway i can fix this without formatting it?
Any help would be apreciated, Please help asap, this pc is newly bought this year. (it has been custom built by the way)
