The latest version of Ubuntu is too large to fit on a CD (it requires a DVD or a large flash drive). The version of Ubuntu on this page has been compressed to under 700mb to fit on a CD. The only difference between this version and the official version is that this version has been recompressed with LZMA2, whereas the original used DEFLATE. Currently, this version will fit even on a 650MB CD, such as those made by MAM-A (Mitsui) or Taiyo Yuden / JVC.

This version is NOT official, although it doesn't have any packages added, removed, or changed (except for being recompressed) as compared to the official version.

Download here: (version 13.10, recommended, UEFI (64-bit only) and MBR (32 and 64-bit) boot working)
64-bit x86_64 version (This is probably the one you want):

In addition, downloads are provided on the "Downloads" tab, but since Google Code limits file sizes to 200MB, you will need to download 4 parts and join them, so it is recommended that you download from the two links above.

Note about Kubuntu: Kubuntu 12.10 (the KDE version of Ubuntu) will not fit on a CD-R, even if recompressed with LZMA2 compression at maximum settings. If you need Kubuntu 12.10 and only have a CD drive, we suggest you install Kubuntu using the network installer. It might be possible to fit Kubuntu 12.10 on a CD by increasing the squashfs block size or using another compression algorithm such as ZPAQ, but this would require a kernel patch, and we would prefer to use the stock kernel if at all possible. Another solution would be to create an install-only CD (no live CD version) based on another installer like the Slackware installer, and use XZ or ZPAQ compression on one large solid tar archive instead of the current squashfs compression. Another possibility would be to use a 90 minute CD-R, which would allow about an extra 100mb as compared to the 80 minute CD-R.

Note about Lubuntu and Xubuntu: The official Lubuntu and Xubuntu 12.10 images are already small enough to fit on a 700MB CD without recompression.
