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

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.

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.
