I had Windows XP on my PC and wanted to install Ubuntu as well because I got more comfortable with it in the past few months.
I downloaded iso, burned it and installed it alongside Windows XP. I didn't change any options about space on partitions etc, it was preset for 21.4GB of my hard-drive.
Installation was successful, but there wasn't an Ubuntu option in the boot menu. Furthermore, one of my partition lost 21.4GB and I can't find them through Windows XP.
How do I boot Ubuntu? And what happened with my partition space? I hope I made my problems clear and hope for quick answers.
