Normally you would just insert your install DVD, reboot, and press TAB at the kboot prompt to select the install option you want. During the partitioning portion of the install you'd have the option to delete all partitions (this does NOT affect the Game OS side) so your existing YDL install would be deleted at that point.
The other option would be to back up your Game OS data, do a format again from the Game OS, restore your Game OS data, then install YDL again as before.
But that shouldn't be necessary -- the first option should work.
