If you don't like the bootloader settings chosen by DrakX, you can change them here.
For instance if you
have several Linux installs on your system and don't want to squeeze all of
their bootloaders into the MBR (Master Boot Record), you can choose to put
the bootloader at the beginning of your new /
partition
and chainload into it from the bootloader of another Linux install
If you have very limited disk space, it may be helpful if you click on and check the box for Clean /tmp at each boot. This may help you maintain some free space.
