Many programs allow one to boot an operating system from a USB; however, with the advent of UEFI BIOS options, some of the older formats of USBs are not as readily bootable on newer machines as before. Therefore, an additional program is needed for users to have a higher degree of compatability between booting operating systems from older USB drives on newer machines.

Enter Bootice

Bootice allows users to install a new Master Boot Record (commonly called an MBR) onto the USB so that it is seen by the BIOS as a device that can have bootable data. While the images on the site are all in Chinese, the program does down in English.

To update the MBR, follow the following instructions:

  1. Choose the appropriate device in the “Destination Disk” dropdown menu.
  2. Click the “Process MBR” button

  3. In the new dialogue box, select the “UltraISO USB0HDD+/USB-ZIP+” radio button
  4. Click the “Install/Config” button.Bootice02-a
  5. In the new dialogue box, click on the “UltraISO USB-HDD+” button. Bootice03

Once you have seen the “Successfully changed the MBR of this disk” message box, you have successfully completed installing a new MBR onto your USB.Bootice04

Now you will be able to install bootable ISOs onto your USB with programs such as UNetbootin and Yumi. Mz
