Hello, I've been trying to re-install my windows but I've failed to. I got a copy of win7 on cd ( it works fine tried it on another pc ), so i got into BIOS to change the primary boot option but i can't find the dvd drive there. One of the options is my HDD and the other one is "disabled". I'm guessing that that is my dvd drive but I don't understand why it is disabled when it works just fine when i put a cd in. Tried to remove the drive and then put it back (found that it might help) but unsuccessfully. Another of solutions I found was to delete upper and lower filters from the registry. I didn't even have those files there. https/imgur.com/a/LfwQSVM - what my BIOS looks like. My laptop - samsung np350v5c s05cz, curr. win. - 10.
