Create a Bootable Utility UFD

3/21/2011

To create a bootable utility USB flash device (UFD), you must partition and format the device to make it bootable, and then you can copy utility files to the UFD.

Hardware and Software Assumptions

• You have gathered the required files for a bootable UFD in a temporary directory, such as C:\utildisk. For more information, see Gather Required Files for a Bootable Utility Disk.

Procedures

To copy the utility files to a UFD and make it bootable

1. From a Windows 7 or Windows PE environment, run the DiskPart tool. For example, at the command prompt, type the following:

   diskpart
   

   Important

   The version of the DiskPart tool provided by both Windows 7 and Windows PE supports the partitioning and formatting of a UFD as a bootable device. Previous versions of the DiskPart tool do not support partitioning and formatting a UFD to be bootable.

2. Use the DiskPart tool to determine the disk number and device size to be used for the next step by typing the following at the DiskPart command prompt:

   list disk
   

3. Use the DiskPart tool to partition and format the device and make it bootable. For example, if the UFD is Disk 1, type the following at the DiskPart command prompt, replacing <device_size> with the capacity of the UFD (in MB).

   select disk <disk_number>
   clean
   create partition primary size=<device_size>
   select partition 1
   active
   format fs=ntfs quick
   assign
   exit
   

   The UFD is now bootable.

4. On the development computer, copy all the files in the \ISO directory of <tempdir> to the UFD. For example, if the UFD drive letter is F and the temporary directory is C:\utildisk, type the following:

   xcopy C:\utildisk\iso\*.* /s /e /f F:\
   

5. You can now use the UFD as a bootable utility UFD for Standard 7.
