I need help creating a valid ISO image from my Win7 Disc

Recommended Posts

Hello everyone,

 

I have done a fair bit of googling, and reading on this particular forum but almost all posts are regarding how to create a bootable DVD from a Windows 7 ISO image.

What I need help with is creating the ISO image from my legit Windows 7 x64 Ultimate retail DVD.

 

The outcome of this is to be able to follow this guide from ARS Technica (http://arstechnica.com/business/news/2009/12/-the-usb-flash-drive.ars) to create a Win 7 USB install drive.

 

I have downloaded the official tool mentioned in the article ("Windows 7 USB DVD Download Tool") and I have then used ImgBurn 2.5.6.0 to create a disc image from my Win7 disc.

 

Steps to create the image file:

1) Start imgburn

2) Selected "Create image file from disc"

3) Set Destination of the image file to my Desktop leaving the default name of the disc alone ("GRMCULXFREO_EN_DVD").

4) Click the big "read" button to start the process.

 

Now, all of this completed successfully creating one ~3GB ISO file and a small .MDS file on my desktop.

 

However trying to point the "Windows 7 USB DVD Download Tool" at this newly created ISO image only returns an error message saying "The selected file is not a valid ISO file. Please select a valid ISO file and try again.".

Does anyone know what to do here?

 

Thanks a lot in advance.

Could you also please copy + paste the disc information from the box on the right when you're in Read mode.

 

The answer to the issue probably lies here...

But I'm curious as to why the udf anchor isn't at the end of the disc in sector 1574703 where it should be.

Here is what's inside the right box when the DVD is inserted and the app is in "Read" mode.

 

_NEC DVD_RW ND-3540A 1.01 (ATA)

Current Read Speed: 6.8x - 16x

File System Information:

Does this help clarify the situation?

 

Thanks again for your replies.

Yes, it does help and I notice there's a difference between the file system reported size and the actual size on the disc. Now I think the only thing that would really help here is to examine every sector and find the last anchor. But that's just to satisfy my curiosity and does nothing to help you!

 

You should just run the tool from the site I linked you to and have it fix the ISO. Then the MS USB/DVD tool should work fine.

I ran the USB tool and now the ISO image created by ImgBurn is working just fine with the MS USB tool.

If you would like to satisfy your curiosity let me know what I could do to help.

 

Thanks a lot for your help!

I think the disc just wasn't created/burnt (pressed) correctly in the first place.

 

If you'd used ImgBurn to build a new ISO (by just adding 'E:\' to the 'source' box), it probably would have created a new ISO that you could use with the USB/DVD tool.

 

Another option may have have been to trim the ISO made by Read mode to a size of 3,224,686,592 bytes.

 

But anyway, you've got it on USB now so no need to keep messing with it :)

Quality control at Microsoft aye.. you'd think that at least that part they get right when charging this much money for 1 disc :)

 

Anyway, it's working now so thanks again for your help.
