Hello, i have new company PC with freshly installed XP and i want to use it also for my private activities (gaming, testing, driver tweaking, research...) withouth touching the original system and installed programs. So i plan to make another clone of the fixed disk and put it on the ESATA removable HDD (plextor)and customize this system to my needs (and point location of MyDocuments to E drive). When removable drive isn't connected, the system has to boot directly to working system and use user files / mail / data on drive E; but when removable drive is connected, it has to boot from system on removable HDD and use same user files user files / mail / data on drive E. I'd like to know: - how to do that - is it possible to fix the location of working/data/mail files on drive E for both systems and make C: fixed drive and D: removable drive, and then when D is connected, boot from D - how to select that removable disk will get allways the same drive (C od D) - how to do it with as few changes to fixed drive system as possible - what about multiboot menu on usb removable stick for selecting D as boot disk - where are tricky parts and wht am I missing? - using two removable HDDs , one for company and one for private system, seems a little awkward. Please, can anyone point me in right direction. Thanx in advance.
