USB flash drive for Windows 7 Download Tool cannot start installation Windows7 SP1

Previously installing WINDOWS7 with this tool has been normal and has not encountered an issue that cannot start the installation. Windows7 SP1 out, use this tool to make the installation of multiple machines can not boot installation (brand and compatible machines are so), either stay in the cursor flashing state, or no reaction. The reason may be a compatibility issue (allegedly this tool is used for netbooks), although the use of UltraISO can be produced and successfully installed, but the following methods with Microsoft's own commands can be produced, the method is as follows:

One: Prepare a USB flash drive of more than 4G into the computer, run CMD as Administrator, run the following command (in the Blue Font section) to complete the partition formatting of the USB drive.

01. DiskPart

02, list disk (have this to get the number of the U disk, must not be mistaken!!) It's a mistake. All contents of other disks will be deleted)

03. Select disk? (?) The number of the USB drive that appears after the list disk. Remind again: Must not mistake!! It's a mistake. All contents of other disks will be deleted)

04, clean (empty the contents of the USB stick)

05. Create partition primary (creates the primary partition. If it is a large active hard disk, you can set this: create partition primary size=4096, which creates a 4096M, 4G size partition so that the remaining space on the hard disk can be partitioned later. ）

06. Select partition 1 (move focus to current partition)

07. Active (Marking the current partition as Active)

08. Format Fs=ntfs Quick (fast format of current partition)

09, assign (assign a drive letter)

10, exit (quit DiskPart)

Two: Copy the installation file:

Copy all the installation files on the source disk's ISO CD to the USB drive.

Three: Write USB flash drive Boot information:

Run cmd as Administrator and execute the following command (in the Blue Font section):

Bootsect/nt60 x: (where Bootsec is located in the boot directory of the ISO CD root, X is the drive letter of the current USB drive in the system)

Four: Install using a USB flash drive:

Set the computer to boot from the USB stick, insert the USB flash drive and enter the same installation interface as the disc.

Five, using the above method to make a USB flash drive in the original Windows 7 USB DVD Download Tool can not start the installation of multiple machines will be able to start the installation normally! Also available on Windows R2.

If the USB stick is large enough, you can also copy other files in the USB flash drive without affecting the use. But must pay attention to the security of the U disk, can not be poisoned!

Six, 2012.10.15 update: After using this method, for some brands of motherboards (such as: gigabyte) or can not start the USB stick, the solution is to format the USB stick to FAT32.

PS: The fastest way to make: Format the U disk (note the 6th above), copy all the installation files to the USB stick after running (pay attention to the 3rd above): Bootsect/nt60 X:
