I have an HP laptop, forgot the series but a its a some what newer model (windows 7, intel core i3, etc...). my issue is, the laptop initially had windows 7 installed, then i forgot my password so i reformated it and installed ubuntu on it. it was working fine for a few months, but now it wont boot all the way. it loads partially, ubuntu logo pops up but then goes blank after that. Now, i got a windows 7 CD/DVD from one of my friends and i am now trying to re-install windows on my laptop. i tried booting from the CD but for some reason it wouldn't let me. i even tried re-installing Ubuntu (which is on a USB) but it wouldn't let me do that either. im not sure if the laptop needs to be "reflowed" or not. any advise?
