Your bootfile has been messed. Clear CMOS memory by removing the battery from the motherboard or using the jumper to reset it to default. The easier way is to just press esc on startup to restore it to default using the software but since it's stuck on the bootscreen, you cant do that.
Disconnect your harddisk power and swith on the computer with the windows 7 disk in your dvd-drive. Keep hitting f8 or del (Depends with different motherboards) to choose booting options. Boot using the windows 7 dvd, choose your language and click on repair commputer.
That should do the trick!
Clear CMOS and retry. Go into BIOS and turn off the boot logo option. Then find out where it really is having trouble.
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.
