so after my pc broke i had to replace the new hard drive, the problem is i dont have the recovery disk and motherboard is OEM to that windows 7 OS meaning i cant buy a different windows 7 OS. also my windows 7 serial code is half torn so i dont know the whole code. but then i was told i can order the recovery kit from HP support and im not sure will it also come with the windows serial number? will i need the windows serial number if i will already have a recovery disk? or will it have nessesary recovery disks and the serial for my windows 7 OS?
