I have an HP Pavilion ze4427wm laptop. My cd rom hasn’t been working for a while, which is no big deal. However, due to a virus I needed to format the hard drive and install windows. I removed the hard drive and connected it to a desktop with cd rom using an adapter. Windows installed, and runs fine on the desktop but will not boot on the laptop. The bios setup is password protected and I lost the password, but I can change the boot source. My question is if the bad cd drive is keeping windows from booting.
