Win 7 USB Tool Problem

[vegettoxp]

Hey Guys, I was trying to use that Win 7 USB.DVD Tool that MS released and I was having problems using it. My Win 7 Ultimate (x64) I got a free copy from attendinf those MS Conferance for Win 7 Launch. Everytiime I point the tool to the ISO, I getting the following error, "The Selected File is Not a Valid ISO, Please Select a Valid ISO and Try Again." Has anyone else had this issue. Please help me out guys.

Thank You!

You don't really need it, although it is nice when it works. It takes three steps to accomplish this manually (using a Vista or Win7 host makes this a bit easier later on):

1. Clean, partition, format, and mark active the primary partition on the USB key (this should be obvious) via diskpart - FAT32 or NTFS, your choice

2. Create an /nt60 bootsector on the key via bootsect.exe

3. Copy the contents of the ISO to the USB key

That's it. Bootable USB install key.
