  • Troubleshooting Issues with Multi Booting Computer\Device

Some Basic Definitions:

Dual Boot - A device which contains two Operating Systems, and can 'boot' into both, usually with one bootloader (GRUB most common for Ubuntu)

Multi Boot - A device which can boot into 2 or more Operating Systems. (see above)

Partition (also sometimes known as a Volume) - A logical way to divide space on a disk. This will be formatted with a filesystem (ext, NTFS, FAT, ...)


Brief Introduction to the Subject:

Dual booting, or Multi booting a system is useful, because one can have different versions of Operating Systems (OS), for specific tasks, or for compatibility. A bootloader, (such as GRUB, LILO, or Windows Boot Manager) will give access to the specified OS which will then have control of the system. Often separate OSs are on separate partitions, and the boot records (which control how the bootloader knows what OSs are available, among other things) can be on a single partition, or multiple partitions.
