Re: Move hidden partition from Asus laptop to external USB HDD and boot from there
That hidden partition is like a recovery for the preloaded OS that it came with, with all the manufacturer's settings, etc. It makes no sense to move it to an external or anywhere as a matter of fact if you are going to do a clean install of Windows XP. Also it will not be able to restore your settings to factory defaults without the correct OS in place (where you would need the Windows Vista...and not the Windows XP), which would render it useless.
Need to update my siggy!
