Ultimate Boot CD is a bootable recovery CD containing software used for repairing, restoring, or diagnosing almost any computer problem. Its goal is to be the most complete and easy to use free computer diagnostic tool. Almost all software included in Ultimate Boot CD are freeware utilities for Windows. Some of the tools inlcuded are "free for personal use" copies so users need to respect these licenses. A few of the tools included in UBCD are paid for and licensed software owned by UBCD4win. On occasion the developers work with software companies \ authors for permission to include their software in the download or have requested their software better support PE. Users can freely share copies of Ultimate Boot CD with friends but selling Ultimate Boot CD for a profit is not acceptable. 

The developers have worked hard for many years helping people for free with this project, others should not make money from their hard work. If you are a dialup user having a hard time downloading Ultimate Boot CD, please visit the ordering page. UBCD is based on Bart's PE, which builds a Windows "pre-install" environment CD, basically a simple Windows XP booted from CD. It includes network support and allows you the ability to modify NTFS volumes, recover deleted files, create new NTFS volumes, scan hard drives for viruses, etc. The download includes almost everything you need to repair your system problems. Please note that this project has been put together to be the ultimate recovery cd and not a replacement OS (Operating System).
