works like a charm fantastic software
What if there is no ETFS*.com* boot , but an EFI
Click on show all files instead of show bootable image
Thanks, Kiran. 🙂
Basically, Windows 7 supports ETFS.com boot file whereas windows 10 support EFI file. So select according to your Operating system.
Do you have to change the sector to load number when you chose an EFI file instead of the ETFSBOOT.COM file? I am trying to create an ISO from a bootable Windows 11 USB drive and could not get the ISO to boot after it’s created.
Excellent tutorial, btw. Thanks!
If you are converting Windows 11 USB to an ISO file, then just go to the Boot folder, and then you will find an etfsboot file which you have to select as Boot Image, after that change the Sectors To Load as 8. Once all these settings are done, just follow Step 4 mentioned above.
Hope it helps 🙂
Using the link above, McAfee declared it contained a virus and immediately erased it
Yes, some antivirus detects it as a virus but it is truly safe and will not harm your machine & files. While downloading it, please turn off your antivirus & after installation you can turn it on. 🙂
Thanks for sharing this information, maybe you could show how the “build” button looks like since is an ICON no text.
Sure! Will update this soon. 🙂
In the Boot folder on my USB drive there is no etfs.com but in \EFI\Boot there is bootx64.efi. Would I use the latter? Or which efi file?
Could you please tell me which Windows operating system files are you using for creating ISO image file?
It created an iso file all right, but Hyper-V refuses to boot from it 🙁
In that case, I would suggest you to re-download the ISO image file from the official website and then try. Because we have seen that due to some lost files the ISO image doesn’t boot properly.
And if the issue still persists with the new ISO file, then check whether your boot settings are correctly configured or not.
Hope it helps 🙂
Doesnt seem to work – Windows 11 latest IMG burn
I have no EFI or UEFI folder as they are on a separate partition on USB harddrive (SSD accessed through USB)
seems like i have to do it in linux
I haven’t checked it yet on Windows 11 but soon I will revert you with the answer. But for now, you can surely do that in Linux.
Does this work on other bootable USBs? I am trying to make a backup of my Revo Pro USB stick in case one of the PCs I am working on corrupts it.
No, I don’t think it will exactly work like a bootable ISO of Windows but you can still try it to make an image file.
My Dell Recovery USB drive for Windows 10 Pro gave me a error when it ran;
Directory depth exceeds ISO9660 limit of 8 levels.
Number of directory levels in path: 9
Most directory levels in any path: 9
Would you like to continue anyway?
Of course I said Yes. When I checked to see what was in that folder and it only has a Alienware Digital Recovery shortcut. Since this isn’t an AW product I’m hopeful.
Could you please describe to me more about the issue you are facing? Because we have used this process plenty of times for Windows 10 but I am not sure about that it works with Alienware product or not.
