Siduction, as a Linux LIVE DVD/CD, is heavily compressed. Therefore, please be careful when burning a CD/DVD to install from or run live. Please use DAO mode (disk at once) and do not burn faster than 8x. Nowadays it is much easier and more convenient to just use dd or cat to transfer the iso image to a USB stick and boot directly from it. Please read the section about installations in the manual.
