Yeah, had a struggle late night, and have come to the conclusion that Vista doesnt like my notebook(Dell Inspiron 6400). To be precise it prefers me to stick with Windows XP Home Edition, and is reluctant to upgrade it. The compatibility report was fine, the only Hardware complaints were - to Upgrade my Bios - i.e. got to A.11 from A.8 The software complaints were - Nero - which I can do without for the time being - McAfee Internet Suite - OMG, no compatibilty with McAfee, allright I'll give Avast...
