PeToUSB

PeToUSB is a small, simple, easy-to-use, smart and reliable 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.

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.

- Rewrites the MBR code just in case its corrupted.
- This option can be disabled if desired.
- On Removable media, the partition is completely rewritten.
- Backup/Restore MBR.
- View disk information.
- Assign drive letters.
- Automatic notification of device arrival/removal.
- Supports WinPE builds as well.

Is a small software, but very useful. detects automatically flash drives from USB port and you can make some actions like quick format, force volume dismount, re-write or not MBR, enable UBA.

Also, from File menu you can backup or restore MBR settings.
