Scenario:
New laptop (supporting USB boot in BIOS) running Vista.
Would like to boot XP from perfectly serviceable HD from old (otherwise U/S) laptop, via USB connected HD enclosure.
Seems simple, but for a whole variety of (Google) reasons I gather may be a "no no". Certainly the case on initial try, but I can appreciate all sorts of reasons possibly why (boot files, etc).
Can anyone enlighten me as to whether this is a quick 'goer', or not?
Thanks, as always.
