Before I post my problem, I just thought I'd say the guys who know what they are doing and spend time on here helping the less savvy are doing a massive favour.
I'm installing 8.10 for a friend, I have installed from DVD on what will be a hybrid, ran updates as per the walk through, and now I am at the AV Wizard stage. When the wizard starts, I select my options in step 1, but then clicking OK or pressing enter causes the wizard to relaunch (it's like a reboot almost, but much quicker and not shutting Kunubtu down).
I have an NVidia 4670 HD graphics card, and an Asus M4A88T motherboard. The onboard graphics on the MB (ATI - boo!) have been disabled.
Is there any other info I need to help diagnose this issue?
