Running XP 120GB HD.Have a 80GB ext.HDD.Rather than partitioning and dual-booting on sameHD,I’d like to place linux os on external because I’ve heard there is a MBR conflict w/ linux 2.6 kernel. The ext HD is USB.If I keep connecting and disconnecting the ext. for traveling,will any problems arise? OR-if anyone has experience w/ XP/Linux SUSE dual boot on same HDD,give me your input as to which would be the better and the safest course of action
