    99 You should be able to return to the graphical installer to do the rest.

    101 === Using the Installer ===
    102 
    103 Choose manual partition in the Debian Installer. Then:
    104 
    105  * Choose "Congifure software RAID" (skip step if one disk system)
    106   * Choose "Create MD Device"
    107   * Choose RAID1 for boot partition and RAID10 for big partition
    108   * Number of active devices: 4
    109   * Number of spare devices: 0
    110   * Now select the second partition on each device.
    111   * Click Continue. Repeat for third partition on each device but select RAID10 instead of RAID1.
    112   * When you are done, click Finish. Now you are back at the partition menu.
    113  * Scroll down to the raid devices (or apply straight to your partitions if it's a one disk system). Modify the 512 MB RAID device: Filesystem: ext3, mount on /boot
    114  * Encrypt the larger, remaining device. Save passphrase in [wiki:keyringer].
    115  * Choose "Congifure LVM" (selecting the device encrypted in the previous step)
    116  * Create a volume group called `vg_`''nameofserver''`0`
    117  * Create logical volumes in this volume group based on your needs. Suggestions: 3GB for /, 1GB swap.
    118 
    119  * After returning to the main disk config menu, click on each logical volume that you create and specify how it should be formatted and mounted.
    120  * Enter root password. Save in [wiki:keyringer].
    121  * Do not install the server package or the base package - deselect all of them.
