• Installing Debian testing On GPT HDDs (> 2TB) From A Grml Live Linux
  This tutorial explains how to install Debian testing with the help of debootstrap from a Grml Live Linux system. This should work - with minor changes - for other Debian and Ubuntu versions as well. By following this guide, it is possible to configure the system to your needs (OS version, partitioning, RAID, LVM, etc.) instead of depending on the few pre-configured images that your server provider offers.
