Hello, I think I understood half. you can not start windows right?
as well decis, do not bring these pc cd recovery, but a recovery partition that would come fulfilling the same function.
when you start the pc and do the bios check, you'll probably appear samsung screen. appears when you press the pause button on the notebook and read the options it gives you. surely it is eg f2 f11 boot menu menu bios and stuff. select the one that says recovery or something like that.
That will be taking a series of steps to recover your windows as it was manufactured. generally brings options to not lose the files but you better use the option to reinstall from 0 because it is less likely to bring post-repair faults.
I hope you serve and understand well. consultations me anything.
regards
