After having a virtual version of Ubuntu 12.04 on my Windows 7 computer for a while, I intended to install Ubuntu 13.04 on the computer itself today in parallel with Windows 7.
Since I don't have a USB drive with a large enough capacity at my disposal currently, I decided to just use a DVD+RW. After downloading the ISO image file from Ubuntu, I proceeded to format my disc as mastered and to burn the contents of the ISO onto the disc. This all worked successfully, however when I booted from my CD Drive, I ended up with a File Not Found error. After a little searching on the internet, I found that the fix was to rename a particular file by removing the extension from the file's name. Easy enough for those using a USB drive, but once burned to the disc, I was unable to alter the file name.
My next step was to extract the contents of the ISO using 7-Zip. After reformatting the disc, thus clearing the disc's contents, I proceeded to fix the one file name, and burn all of the extracted files onto the disc. When I then booted from the disc, an Ubuntu screen did come up, however it got stuck on a loading screen and I figured it was due to how I was burning the image.
My final attempt was to take a second DVD+RW disc and format it as a Live File System. I have relatively little experience using CDs and DVDs for this sort of thing, and the majority of my experiences with them have been less than agreeable. However, nothing I read on the internet indicated that this was not a plausible solution.
My first hurdle with the second disc was that windows would not allow me to burn the ISO image to the disc because it was not writable... So my next step was to copy the extracted contents onto this disc and see if it might work now. I'm about to try it, but I'm highly skeptical.
I also have a 1TB external hard drive which will surely be my last resort. However, like I said, I don't have much experience doing this sort of thing so I really just wanted to take the least complicated route with the DVDs.
Any help on how to install is much appreciated.
EDIT: Tried the Live File System. Didn't work. I think it's because the disc cannot be booted from in this format.
