Troubleshooting the boot process

This page is a work in progress. Please help me improve it by pointing out errors and omissions. Also by letting me know of any authoritative resources on this topic. Please, I'm begging you: email me!

We see quite a few questions related to the boot up process (especially in multi-boot scenarios). So I thought it would be a good idea to start a page on troubleshooting it.

Because I think that the best troubleshooting tool is an understanding of how things work, I will start with a flowchart that gives an overview of the complex and hacky boot process. This first draft covers only the Windows MBR-type boot process. Later I hope to add information covering GRUB, LILO, and UEFI/GPT processes.
