Mac – Is it possible to boot backtrack from usb on a macbook pro

I was able to install Windows 8.1 by

• Created a BOOTCAMP partition using the 10.6 Boot Camp tool (latest version available for 32-bit Macs)
• Creating a Windows 7 USB stick on a PC using http://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool
• Install rEFInd http://www.rodsbooks.com/refind/
• Start Windows Windows 7 installation
• During disk/partiton select, choose to format the BOOTCAMP partition as NTFS (still, it refused to install)
• Restart Windows installer, second time it would recognise partition as valid
• Install Windows 7
• Update to Windows 8

However, the Apple drivers for MacBook1,1 is pretty outdated unfortunately. Also, I would say that Windows 7 is a more appropriate OS for MacBook1,1.

Why use Linux for this? Just do it in OS X. To prepare the USB drive (e.g. 8-GB flash drive), you need to partition it using the GUID scheme and format it to the file system standard 'Macintosh Extended (Journaled)', also known as 'HFS+ (Journaled)'.

Then use Disk Utility's Restore feature to copy the contents of the iso image file (Source) to the USB drive (Destination). When done, restart the Mac keeping the Option key pressed – the USB drive should then show up in the boot volume lineup...

There are many tutorials for this process on the Internet, e.g., http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
