So I have a Sony PCG-71312L (Model: VPCEB15FM) who's CD reader won't read my Windows 7 installation disk! The disk is a Windows 7 Pro x64-bit. I tried installing it through a USB bootable drive but all it does is hangs during installation! It hangs because there is a USB plugged into the ports, but, how else am I suppose to install the win7 without the USB? So I need help.
My alternate option is to not upgrade it to Win7 Pro, and use a clean Win7 Home Edition (btw, the win7 pro disk is cracked/activated, but I uninstall the key and use a legit key i bought to activate it correctly <- and this is probably why the disk won't boot). But I do not possess a clean installation disk of Win7 Home Edition. If anything, I can an ISO of one and burn it into a CD, but I am not sure if I should waste a disk doing so. Please help.
