I have decided to install Ubuntu on my laptop alongside Windows 8, the OS I have currently installed and that I don't want to uninstall because I need some programs.
I have downloaded the ISO and burned it into a CD. Everything in the installation goes well until I have to choose where to install it. It doesn't recognise my Windows 8 and it sees my disk as if it was all empty space (500 GB).
What should I do to install Ubuntu?
If the "Something Else" partitioning option is showing the disk as completely unpartitioned, then chances are you've run into a libparted bug that causes tools that use that library (such as the Ubuntu installer) to think the disk is empty when in fact the partition table is not to libparted's liking. This problem can often (but not always) be fixed by my FixParts program, which is part of the gdisk or gptfdisk (I don't recall which offhand) package in Ubuntu. See this page for more on this problem.
