UBCD4Win is based on Barts PE. Barts PE builds a Windows "pre-install" environment CD, basically Windows booted from CD. We include many free hardware and software diagnostic tools that allow you to fix almost any problem you will face with your computer.With network support, the ability to modify NTFS volumes, recover deleted files, create new NTFS volumes, scan hard drives for viruses, etc. this project includes almost everything you need to repair your system problems. This project has been put together to be the ultimate recovery cd and not a replacement OS (Operating System).
