Error when trying to use WinToUSB to install Windows 7 Ultimate onto a pendrive

Question

I wanted to install Windows on an USB drive so that I can use it on different computers. I heard about WinToUSB and gave it a try. At about seventy percent (with three retries) I get an error "Copy file failed.(0x0000008000B40000)". I am using Windows 7 Home Premium, trying to install Windows 7 Ultimate onto a Kingston DataTraveller 3.0 (USB 3.0).

What can I do? I tried three times.

I appreciate any help.

I am NOT talking about installing Windows FROM a pendrive but TO a pendrive.

Update:

I contacted WinToUSB support and after looking at the log file they told me that the iso file I was trying is corrupted. I am going to download the ISO from DigitalRiver and try to see whether it works. Link to forum: http://www.easyuefi.com/forums/showthread.php?tid=41

Solution 1

I downloaded the file again and it worked. I think the best solution to prevent this would be to check the Hash of the downloaded file before using it.

Thanks for all the help provided.

Solution 2

From WintoUSB installation notes:

"Windows 7/2008 R2 does not have built-in USB 3.0 support, so Windows 7/2008 R2 will have to be booted from a USB 2.0 port."

So did what you described in the update work? If so, can you post an answer describing the solution? That will help others with the same problem. Thanks.

According to many articles, WinUSB maker only allows you install os from lettuce. WinToUSB is like Windows To Go. You can use the OS straight from the pendrive, after installing it on the pendrive. However, thank you for your answer.

Even though I have a USB 3.0 pendrive, I plug it into a USB 2.0 drive. I have already read through the install notes.
