zBoot Manager is an effective boot manager and partition manager, which allows you to easily install and use multiple operating systems on a single hard drive. It supports most types of systems such as DOS, 32-bit Windows and Linux, and you won't have to reinstall the system you're using right now. You'll be able to install up to eight operating systems, which may have up to four partitions each. zBoot Manager eliminates the need for FDISK and directly setup 32 primary partitions with the built-in utility. Once set-up, the program displays a menu whenever you boot up, you simply select an operating system to run it on your computer. For security, selected systems may be password protected. This vesion can boot from a 2nd hard disk.
