Installing XP Pro (tablet edition) from USB stick (HP 2730p)

Basically:

Used a software that creates all the necessary boot information for the USB drive, found here:

Original Problem:

Had a HP 2730p laptop which has no internal CD drive and would not boot from any external CD drives I had. Boots from USB stick fine though so getting a bootable USB solution is what worked. It needed to be loaded with the Tablet edition of XP Pro.

How to solve it:

The software from the link above provides an easy enough GUI to make a bootable USB. Basically I installed it onto windows XP VM and ran the software over a USB stick. Formatted it with NTFS and pointed the source to the first (of 2) CD's for XP Pro Tablet edition. It will do the rest itself and provide you with questions that need to be answered. Quite a useful piece of software.

Once you boot from USB it will automatically select the settings to start the windows install. You can actually put more than one install on the flash drive with this software so it will ask you what one you are wanting to install. Just let it do it all automatically if you only have the one OS on the USB stick.

Also tried a win Vista/7 'apprently' easy USB install, but obviously doenst work for XP. It also needs to be created with Vista/7 as the version of diskpart in lower OS releases doesnt have the same function:
