Burning a Live DVD
Please note that the current image is about 1GB in size, and will not fit on a CD, you must use a DVD-R or DVD-RW. The first step of any of the below is to download the .iso image from the PyDAW downloads page, please see the pydaw.org website for details.
Images can be burned using the ImgBurn utility available from the ImgBurn website. The ImgBurn site has instructions for how to burn an .ISO image.
The available utilities for burning an .ISO image vary between distros. Most will use either Brasero or K3B, check your distro's website for instructions.
Creating a Bootable Flash Drive
You need to create a 2nd partition on the flash drive in order to be able to store projects and samples, audio, etc... In Linux you can use DiskUtility or GParted to partition the flash drive before creating a live USB drive from it, or 'diskpart' in Windows Vista/7/8. There is also a Windows port of GParted. If any Windows users would care to create a tutorial for properly creating the partitions, I would appreciate it.
The first partition should be about 1.5GB(extra room just in case the image gets bigger later), and the remainder goes to the samples/audio/projects partition that I always name 'pydaw_data' for consistency. You most likely want to use the FAT/FAT32 filesystem for both partitions, unless the flash drive is too large for FAT, then EXT4 is preferred. If you're not using FAT, you may need to run the following command from the Linux live USB terminal to give appropriate permissions to the drive:
sudo chmod -R 777 /media/your_partition_name_goes_here
Do not use a persistence file on a USB flash drive. It will run an order of magitude slower because of the lack of proper asynchronous IO.
The following documentation covers the various ways to create a live USB flash drive from Windows, OSX, Linux, etc...
Saving Settings Between Sessions
Starting with PyDAW-OS 13.05-3, if you create a partition on your flash drive named 'pydaw_data', PyDAW will automatically save it's settings there instead of /home/ubuntu/pydaw3 when running as a live USB.
