So we cannot run the Windows 7 setup.exe from Windows itself. To further complicate things, the reason I am trying to install Widows with a bootable USB, is that the computer only has guest user access (One guest user account, and one administrator account with an unknown password). I tried to run WINCRIS on Windows 7 X64 and I get the 'Warning, there are no removeable devices in the system', but I have success running it on Windows 7 X86. When I extract my files from the downloaded ISO, I only have the following I bought my copy of Windows from the Volume Licensing Service Center, and downloaded the ISO directly from Microsoft, so I have no physical media, and the ISO itself appears to be somewhat different from what people describe if they own the DVD.įor example, some of the guides I have read mention extracting the ISO (the one from the DVD) so that the user has access to bootsect.exe, and other files important for creating the key. I think the most important thing to note in my case, is that in all the guides I have read the people having trouble creating the USB key have gotten their Windows 7 ISO from a DVD that they own. The furthest I have gotten is an error saying "BOOTMGR is missing".
I have read several different methods for how to create the USB key, most of which have not worked for one reason or another. To using the "Windows 7 USB DVD Download Tool" to create the USB drive after having downloaded a third party application and getting a bunch of bloat ware and malware from the program (even though it was a highly rated CNET download).
I have a 64GB USB key that I am trying to use to create a bootable USB install disk. This computer does not have an optical drive, but does have several USB slots. I have a computer that I need to reinstall Windows 7 Professional on.
