I get this error: "unexpected error occurred (0); unable to upgrade firmware" They refer me to this site: http://support.apple.com/kb/HT2434?viewlocale=en_US I just bought this late 08 MBP and I have a bootcamp partition running Windows XP Pro 32Bit on a NTFS partition. Why is this so complicated? Macs have always been easy on me until this lol. They tell me to do a full reinstall but I don't understand how this will fix the problem since I don't know where this comes from. It says to go check my "Partition Map Scheme" and I have a "Master Boot Record". It says I need a "GUID_partition_scheme". How come I don't have a "GUID_partition_scheme"??? Thanks, I'm lost.
