computer won't start after using recovery system/windows couldn't inst
I did a recovery system to my computer and when it was restarting i accidentally unplugg the computer so when i turn the computer back on, the computer starts with a message saying "setup is starting service" then i get another message saying "windows could not complete the installation. to install windows on this computer, restart the installation" i click ok on the message then i get another one just saying setup will continue after restaring your computer and is the same thing everytime i try to boost the computer. I'm not sure what to do or if I should just buy windows 7 home premium (which iswhat the computer came with) and install it but i'm not sure if this is the way to fix the problem can anyone give me any advice, also i've been looking at windows 7 Hp and there is the full version and the 64-bit - System Builder (OEM) which should i get?
thanks in advince.
