Ubuntu CD burn crash - HELP!!!

[Gabecoolio]

I was trying to write Ubuntu 17.04-Server (685mb) on a 700mb CD. I used "Free ISO Burner" and at 97% the program crashed while burning. Does this mean my Ubuntu is broken on the disk? Can I still re-use the disk if it is broken? Please help me!

What CD is it? 

There is CD-R and CD-RW

CD-R means you can only record it once

CD-RW means you can rewrite as many times as you like

CD-R :-(

I can help here. FIrst up, that CD-R is toast. It's an incomplete write, so don't try and use it for anything above and beyond a coaster.

 

Instead, here's a few steps to make this easier. First, let's check that your ISO file isn't corrupt or anything. You'll want to run something like Quickhash: http://quickhash-gui.org/

 

This lets you compare your iso file's checksum against the correct ones from ubuntu here: http://releases.ubuntu.com/17.04/MD5SUMS

 

Run the MD5 option in Quickhash and check to see if it matches the corresponding file on the Ubuntu site.

 

If it does, great! Just burn it again, only this time try ImgBurn. I've had much better luck with it. http://imgburn.com/

 

At that point, you should be good to go, or you may have to redownload Ubuntu, but still, it's easy to get things fixed from here.

 

If you have any questions, let me know!
