WinSetupFromUSB is A Tool To Make Windows Setup To USB Flash Drive
What it can be used for adding to your USB stick/disk:

- multiple Windows XP/2kX sources in the same partition (up to 10). They have to be in the first partition of the disk! Existing folders ~BT and ~LS and TXTSETUP.SIF will be renamed, and SETUPLDR.BIN and SETUPDD.SYS patched against the new names. Checksum checks are also corrected. BTS OEM folders are supported and renamed accordingly.
- BartPE/WinBulder/UBCD4Win/WinFLPC (NOT ramdisk versions) to any primary partition. Multiple BartPE for example, in the SAME partition are NOT supported. Neither is the mix of them on a single partition.
- Vista/Windows 7 setup to different primary partitions. Multiple Vista sources in the SAME partition are NOT supported. Place your second Vista setup in another partition. It can be placed on any primary partition.
- PartedMagic, a friendly Linux distro including GParted- open source partition manager.
- SyLinux bootsector, and optionally a directory, containing (Linux) distro booting off SysLinux. For example you may extract UBCD411.ISO, and point it to this folder. Entire contents will be copied and entry for SysLinux will be added to the boot menu.
