ISO Image Extraction Failure Rufus

What can I do?

1. Check the MD5 of your ISO which too few people know you can ACTUALLY do using Rufus! Just click on the (✓) button next to SELECT (Rufus 3.0 or later) or the # button at the bottom of the Rufus interface (Rufus 2.18 or earlier) after selecting your ISO. There is no need to use another tool.
2. Run a bad blocks check in Rufus, to make sure that the issue isn't with your flash drive.
3. Report that issue in the official issue tracker for Rufus, along with your full log from Rufus, as this is the best place to get help with Rufus issues.

for me the case was that I deleted the rufus_files folder rufus created when it's ran for the very first time. Actually, I keep a different folder for softwares, so i only copied .exe after i did my first iso extraction with rufus and deleted the folder (rufus_files).

so, just reinstall rufus and keep the folder.

Mine was failing because my Front USB ports on my case was causing write failures to the thumb drive. Plugged in the back ports and all was good.

I was trying to create the bootable USB from my office laptop and got in to this issue. I have read many solutions and it didn't work out. From one answer they said it might be due to the anti-virus effect and i tried using my personal laptop and it did work out.

If you are trying to use an ISO located on a network share, copy the file to a local hard drive.

On Windows install the program PowerISO. Then:

1. Open your ISO file.
2. Delete autorun.inf.
3. Save and exit (overwrite).

Done.

For me in Windows 10, it seems that MS denies rufus access to items in downloads and desktops, so am unable to actually choose/select the Ubuntu image to send to USB stick.

Just run rufus as administrator and it works on Windows 10. Otherwise it cannot find the iso file or downloads folder.
