I used my usb drive to install xp w sp3 using the usb_multiboot tool so thank you for that! however, I was wondering if there is anyway to multiboot with backtrack as well. i have a 4gb usb so my only options for formatting are fat32 and ntfs -- but fat32 has the problem of being very slow in installing xp -- on the other hand, i dont think i can boot syslinux or backtrack from an ntfs formatted disk is there anyway to create two partitions on the flash drive and have my ntfs formatted xp install run from the second partition? how would i set up the bootloader to do this, while keeping the usb drive recognized as a usb removable, and not a usb fixed drive. basically i want: partition 1 - fat32 - backtrack usb - 3.0gb partition 2 - ntfs - xp w sp3 install - 1.0gb (or less) and when I plug the drive into an xp computer, only the first partition will show (since xp can't show multi-parititioned usb sticks); however when I boot off the stick, I can still run the install. is this feasible/possible?
