Hi,

I want to dual boot OSX with Win7 (via an XP upgrade).

As I have an upgrade copy of Win7 it *requires* that XP is installed prior to allowing the upgrade to Win7.

So far, I have only been able to either:

install OSX (which uses GUID/GPT) and so therefore I cannot install XP, as XP can only use GPT as a data partition and not as a system drive.

or

install XP and upgrade to Win7; then when I attempt to install OSX it complains that the drive is not GUID/GPT compatible and needs to format the drive to this format before installation.

any advice as to how to get both on?

many thanks!
Mr Vit
