PeToUSB is a Win32 GUI application for formatting and making bootable, USB Flash Memory Drives and USB HardDisks and optionally copying the output from a successful BartPE/WinPE build to the device. There are options to backup/restore the MBR on a device.

Boot your BartPE/WinPE from a USB Flash Disk Drive! Also supports USB HardDisks.

PeToUSB does not make the device DOS bootable, it makes it XP bootable (ie: the bootstrap code will look for NTLDR).

To make a UFD bootable requires it to be formatted to FAT16, the partition set as bootable AND the volume boot sector id to be set to 0x80. If all this is done the UFD should be bootable on any system whose BIOS can boot to USB-HDD. Some UFDs partition tables have been set to a starting offset of
32 sectors, this will not be bootable under USB-HDD. It seems that USB-ZIP requires this, USB-HDD requires offset of 63 sectors.

If your UFD still wont boot after this type of format then either your UFDs chipset isnt capable or the BIOS on the system you are trying to boot is either set incorerectly or incapable of booting to UFD.

But PeToUSB does more than just make a UFD bootable. It will also copy all the required files from a successful BartPE build, to the UFD. The all that remains is for you to boot the stick on a system.

PeToUSB Features:
1. Rewrites the MBR code just in case its corrupted.
2. This option can be disabled if desired.
3. On Removable media, the partition is completely rewritten.
4. Backup/Restore MBR.
5. View disk information.
6. Assign drive letters.
7. Automatic notification of device arrival/removal.
8. Supports WinPE builds as well.

Instructions
1. Build you BartPE/WinPE installation. No need to check the CD Record box.

2. Insert your USB stick into the slot.

3. BACK UP ANY DATA, BECAUSE WE ARE GOING TO FORMAT IT!

4. Use Tools/Backup MBR to make a backup of the disks MBR. (This can be restored later if things dont go as excpected)

5. Remove any security options on the UFD as this will mess up any booting process.

6. Extract PeToUSB.exe from its zip archive and run it.

7. First we want to select the USB stick (Destination Drive). In the window check your USB stick has been recognised. There is a drop list containing all the detected removable disks. If you cant see it. Then click the Refresh button. Make sure you select the drive that you want to use.

8. Next we want to get the path to our PE installation. Click the [...] button and choose the path. The OK on. the Browse Dialog will not display until you select the correct folder.

9. Next we want to choose our options. For the first run we need to choose:- Enable Disk Format, Enable File Copy (if you are only wanting to format then leave this)

10. Now we are ready to format the drive and copy the PE to the stick. Click Start button and answer any confirmation boxes.

11. Copying the files to a UFD takes a lot longer than to an IDE drive. So dont worry about it taking some time. Just watch the progress bar for an indication of how long it will take.

12. After successfully completing the above operations. Your stick is now ready to be booted on the target system.
