Id like to see the full How-To on how to use manual partitioning during Ubuntu installation. The existing guides (at least those I found here) cover only automatic part and leave untouched the manual part (or extremely short and contain no pictures).
As LiveWireBT noticed in comments, it is recommended to place root partition onto primary partition on MBR scheme disks. However, it belongs to personal taste. Sometimes it's even better to put /boot directory on primary and leave root on logical partition.
Optionally disable fast startup and probably disable hibernation, if it is activated and you intend to access the Windows partition with Ubuntu. Run powercfg.cpl and navigate to Power Options > System Settings through "Choose what the power button does".
Attention! No, you don't want to erase the entire disk and Windows along with it. Choose the Something else option if you see this screen. (Something else may be the most difficult option to understand, but considering existing bugs you know what you will get.)
I will not cover how to create mdadm arrays here. There are a lot of articles around the Internet. However, there is one major problem: Ubiquity installer doesn't account for the arrays created in the live session, so you'll probably get unbootable system after installation on such array.
Important: Install /boot onto one of partition outside the array because GRUB doesn't support mdadm. In my case, it's /dev/sda3. If you want more quick booting of your system, it should be placed at the beginning of the disk.
Now suppose that we are going to install Ubuntu 11.04 and at first of the installation process we will meet Allocate drive space screen (the most important step in the installation process). In Allocate drive space screen Select Something else to partition your disk drive manually.
Optionally, use the live view in AXIS Body Worn Assistant to check your camera image, making sure that it is working properly and that the camera orientation is okay. For more information, see AXIS Body Worn Assistant in the body worn solution manual.
Operating time varies depending on how you use the body worn camera. The limiting factors of operating time are battery capacity and storage space. These are affected by power consumption and recording bitrate, respectively.
The time it takes to receive the first GPS position after starting the camera depends on the outdoor environment. For example, tall buildings and humidity in the atmosphere can increase the time it takes to get the first GPS position.
To make sure that all content has been transferred to the content destination, remove the extension system controller in AXIS Body Worn Manager before you remove it from the system physically. Then you can remove the camera.
