how to Re-install a pre-installed windows 7 without product key
I have a Lenovo G550 model 20023 laptop, i know it had a pre-installed version of windows 7 and it was erased.
I need to re-install windows 7 to my laptop however i'm facing some obstacles
1- The COA sticker is worn so i don't know which type of windows 7 was installed (Pro. or home premium .. 64bit or 32bit)
2- The COA sticker is worn so i don't see the product key that would be written on it.
3- The hard disk has been formatted.
4- I don't have Lenovo recovery media and it seems that if i can't request them because they don't ship to my country.
any help ?
