First off, I am new to Linux - I have an old computer on which I want to install Linux so I can play around with it. I am attempting to install PCLinuxOS KDE 2011.6, completely overwriting the existing Windows XP installation. Under Disk Partitioning, I choose Erase and use entire disk and click OK. I then get the message: "writing of partition table failed" and it returns to the Disk Partitioning screen. I can't seem to reformat or repartition my hard drive. Thanks for any help.
