Those are the problems that I get on my Win 7...
First, when I turn on my laptop (HP Pavilion dv6000), after the part that is you can choose F10/F12/etc it stucks there for 1min and then a page comes and says:
Operating System not found.
but I should restart it many times till it says Start Windows Normally and goes to Windows 7 Desktop like normal. and a post comes and says that it was a bluescreen (wtf?)
Second I get, sometimes during work with Mic Office it gets stuck there, or in Internet Explorer/Google Chrome and then it just restarts, then back to First Problem!!!
What is the problem with my laptop? is it not good that I upgraded from Windows Vista to Win 7?
