for a old p4 box
is it USB1
or did you add a EXTRA USB2 card
old xp ( no service pack 1,no service pack 2,no service pack 3) machines had the then average USB1 ports
forget about even trying to use a dead slow usb1 port to boot or install
-- it is like SLOW dial up phone line internet -- dead slow
if you have a usb2 card in it ( pci) you mighe be able to boot from that
now as to all these weird errors
XP all by it's self CAN NOT!!!! burn a iso IMAGE
it normally cam with a 30 day free TRIAL of "nero"
what software did you use to burn the iso
AS A IMAGE!!!
just coping it to a dvd WILL NOT WORK
have a look as installing the windows program
-- it is FREE , i i have used it for years
