Somehow I managed to see in bios menu(I think) that my files from windows are there, I don't think I overwritten, but what I have to do to enter windows?
Set the drive containing Windows as your boot drive.
The Linux isn't starting for one of the 999999 reasons a Linux distro might not start.
Windows likely isn't starting because the Linux installation was written over it.
Just reinstall the OS of your choice and start again.
Also check if you have the correct boot drive selected.

Ok, so I solved the problem, I created a recovery drive, and entered the command prompt, and fixed the boot(bootrec.exe /fixmbr). I ejected the USB and booted to windows. I'll be much more careful next time when I'll install Linux.
