Have a macbook pr 17 with bootcamp.

the osx 10.6 partition is giving errors (the black and white multi language message that tells you to hold down the power button..)

have done a permissions repair, run techtool from a boot disc, all have failed to repair.

next step is for me to reintall snow leopard, and as i have no dual layer disks or usb keys i intend to install from external usb drive using the instructions here:

http://osxdaily.com/2009/09/02/install-snow-leopard-from-external-firewire-or-usb-hard-drive-or-how-to-upgrade-to-106-without-a-dvd-drive/

But how do i format the drive from within windows as boot recognisable from mac?

i have partition magic and cannot see ny option for osx extended or “GUID Partition Table” ?

any ideas please?

Windows doesn't support the HFS+ file system. You need to boot from the Snow Leopard installation DVD, run Disk Utility and partition the drive with it before install.

yep, that's the normal route.

problem is i only have an image of snow leopard, and the only media i can fit the image on is an external drive - are there any 3rd party options to format a drive in the hfs+ format?
