Can you see anywhere if i have to play an operating system on my laptop after i reset it?
because i bought a used one and didn't get an operating system, i'm naturally afraid that after resetting without the operating system i won't be able to use the laptop
I don't quite understand your question, is there an OS on it or net?
You can't reset a laptop without an OS.
Close that shouldn't happen.
If you mean Windows reset, you don't have to be afraid.
In the worst case, if you have Windows 10, you can download W10 from the Internet and then reinstall it. But you should first check which version you have (e.g. W10 64bit Home).
Yes it is on, but do not know whether it was already pre-installed on the laptop when buying, or he had a cd and had to play on it himself, because I have to reset it afterwards and I wouldn't have the cd
