a friend of mine's OS (XP home ed) was messed up due to virusses and spyware. I suggested a format and clean install of WinXp.
Because my pc is a lot faster I put their HD in my pc, formatted and installed WinXP and all their software.
When I put the HD back in their system it didn't want to boot. It worked fine on my system.
Is this because of XP security or because my pc is a Intel system and theirs an AMD?
