ok not to worry...

do this...

take ur usb thingy and plug into ur pc and boot into it...

when chameleon shows up, press any key and interrupt it... so u can type something...

type this:

"DSDT=nothing.aml" without quotes

and select the installer disk from the list of drives and boot into the installer...

what that will do is that will temporarily not load the macbook dsdt file...

after u get into the installer, bring up the terminal and repeat the process for ur pc harddrive... it will generate a patched dsdt.aml for ur gigabyte board...

or u dont like typing, simply delete the following file from ur usb drive:

"/Volumes/hackintoshInstall/Extra/dsdt.aml"

if booting the installer without a dsdt.aml on ur giga doesnt work, i cant really help u with that since i dont have that motherboard...

and dont worry about the MBR error... that is normal...
