Next, the partition setup will appear. If a partition already exists and you do not plan on having multiple operating systems on the computer, we recommend that you delete the existing partition before continuing the setup. You will know if a partition exists if you see anything other than Unpartitioned space listed on the screen.
Note: When deleting a partition, ALL information will be lost.
To delete the partition:
Select the partition and press D, then ENTER. Press L to delete the partition and then press ENTER.
Note: If you have multiple partitions, we suggest deleting all partitions, unless you plan on using these partitions. Deleting each of the other partitions can be done using the same steps above for each additional partition.
To create the partition:
If you started with a new hard drive or have deleted existing partitions, select the unpartitioned space to create a new partition, then press C. Specify the size of the partition in MB (the default is to use all available space) and press ENTER.
