Brasero says it won't burn the CD because the file is too big, what's going on?

Question

I have an old computer that can't handle a boot stick install, so i have to create an actual, old fashioned boot CD.

However, the image size for Ubuntu 12.04 is 732MB, which is too large for a CD, which can hold only 700MB.

The maintainers of Ubuntu 12.04 say the image size will never go over 700MB, and indeed, the download size seemed to be 689MB.

Brasero says it won't burn the CD because the file is too big, what's going on?

Solution 1

I use K3B to burn ISO images. For me, is better then brasero.

Try to burn with another CD brand (Preferably do not use CD-RW )

Solution 2

Are you using a 74 minute CD-R? You need to use an 80 minute one.

Solution 3

If you dig deeper, you'll stumble upon this particular URL which has the "CD" images.

All images are <= 700MB and created specifically for "CD"s unlike the official download link which is actually meant to be burned on a DVD. Hope this helps if anyone is still looking for answers to this question.

Solution 4

Try downloading it from the alternative link at the Ubuntu website (the torrent one). It's about 695MB (AMD64), and the Intel one is 687MB.

Solution 5

If you're trying to install Ubuntu 12.10 (Quantal Quetzal), it is too big for CD now, so you need to use USB or DVD install options.

A standard CD has 703 MB. They are marketed as 700 MB for marketing reasons. Having a round number is better, but they can fit around 703 MB, as I said. However, it is not advised to fill a CD completely as the last sectors might not be in a particularly good condition.

Welcome to Ask Ubuntu! Can you include a answer with instructions on how to do that? Leaving a half-answer as a comment can often cause more harm than good. Thanks.

@Danatela You have that meta post backwards. It's comments like this that are considered especially bad (and which that meta post cautions against making), not answers. While this answer ought to be expanded, it is much better that it is posted as an answer than as a comment.

[landroni]

Either way, I expanded the answer proposing an explanation for the Brasero failure.

Cool that's even better! I personally don't consider the accepted answer an "answer" since the question specifically asks what is going on.. but whatever. comment removed
