There are tons of ways. If you have a virus run some virus scanners in safe mode. If you can't boot Windows 7 try to use your hp repair disc.
If it fully crashed and you have no way of getting a Windows 7 CD or you lost your repair disk then you can either A. Pirate it (illegal) or B. Go to a store and buy one...
Insert windows 7 installation dvd and boot your laptop from it.. that might help u... or try running the safe mode.. to restore your previous setting.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
