Hello. I need to do a factory reset on my lappy. Its an Asus A550C. I've tried Restarting then pressing F9 which goes to Windows Boot Manager, the only option is Windows 7 Home Premium (recovered). Then if I press F8 for advance option and choose Repair Computer it says "Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: insert the disc, choose language, click repair.."

I understand Im suppose to get Windows Setup (EMS Enabled) but I don't have that option.

If anyone can help me out that would be great. thanks in advance.

This sounds as if the factory restore system is gone. I'm running into laptops that came with 8, someone installed 7 and left the now unsuspecting laptop owner with a time bomb.

To recover you need recovery media you created when you got the laptop. If not, order them.
