Sometimes you have to try several of the methods to boot a USB installer.

I've been lucky because the easiest works for my Kingston Data traveler: format the stick Primary FAT32 in Disk Management, copy the DVD files over into the root, then boot by tapping the key given on first bootup screen for Boot Menu; stick is usually listed under HD's.

Next is this method: USB Windows 7 Installation Key Drive - Create

Others have gotten it to work using Win2Flash. This YouTube SIW2 posted shows how to use ISO with Win2Flash:

Enable USB in BIOS. If Boot Menu won't come up at boot using key given, enter BIOS setup to set flash stick to boot first, usually found under HD's.

Try making the flash drive bootable. This works even after you've copied data from the DVD to the flash drive.

Enter the following from a Command Prompt. Note: j: is the DVD drive and r: is the flash drive.

J:\>cd boot
J:\boot>bootsect /nt60 r:

The response will be similar to this:

Target volumes will be updated with BOOTMGR compatible bootcode.

R: (\\?\Volume{b10cedf8-f889-11de-95a6-001111e11f77})

Bootcode was successfully updated on all targeted volumes.

Try booting the flash drive again.

If you are mounting the USB flash stick then it is not booting.

If you want to install then you need to boot the stick under USB's, Removable's, or HD's.

If you're running a Repair Install just run Setup file as Administrator.

Since this thread was started we also have a tool to write ISO to flash stick which is much easier: Universal USB Installer with Win7 in dropdown menu.

Is there any way I can recover my personal files after Custom Re-installation (Not upgrade) of windows 7 ????
