Question Old computer doesn't see bootable Windows XP flash drive ?

[kernan]

i made a Windows XP bootable flash drive but I can't open Windows XP install from boot menu on the old computer.

On my own computer i can enter the Windows install menu from the boot menu
but the old computer doesn't open from bootable file.

The old computer has antiX Linux OS and when i connect flash drive to it I can view the flash drive
but I can't enter from boot menu. I change boot menu option from bios. disable hard drive, floppy-disk drive and others, just leaving usb drive enabled. After restart it said this is not a bootable device, but I can enter Windows XP install menu from boot menu on my own computer. pls help me

my flash 16(14.2) GB
NTFS (I also tried fat32)
MBR

the old computer
CPU: Pentium 4
RAM: 500MB
HDD: 80GB (c 37, d 40)
OS: antiX Linux

That kind of ancient PC only accepts ODD and FDD as bootable media. Meaning CD or floppy disc. Maybe even DVD.
