After fiddling with the settings in ubuntu 13.04 I found that i needed to downgrade to windows 7. I have the official boot CD's and can get my laptop to boot the CD. My only problem seems to be that it freezes at the "Starting Windows" screen. I' ve done everything from re-aranging my boot order, trying to boot through ubuntu, cleaning the disk itself, trying the 32-bit disk, and even trying to boot from a USB stick( which my BIOS does not support, or at least it never works). I have an Acer Aspire V3-551G. I'm not new to computers, before you ask. When bootin off the disk the only option i get is to launch the windows 7 installer. I've tried to get to the command prompt on the disk, with no avail(I'm going to keep trying). THe disk is not scratched and is in almost perfect condition. Please help! Thank you in advanced.
