I am running Windows 7 Home Premium 64 bit on an eMachines laptop and it is stuck in a boot loop after uninstalling Linux. I searched around for a solution, and I came across many forums saying you need a Windows 7 install disk to repair the boot file. I talked to my dad and he said that if I have a proof of purchase (Windows is genuine sticker on the bottom of the laptop with the product key) then I should be able to get one for free. Is this possible? And if so, how would I go about doing this? If I didn't give enough info. then please let me know.
