Dual-booting: the pros and cons

A dual boot system is a computer system which has two or more operating system installed in one hard drive. It can be different hard drives in one computer having many operating systems. When the computer is turned on, a boot manager is presented to the user to choose between the operating systems. A boot manager works in a way that it replaces the original Master Boot Record (MBR) with its own MBR so that the boot manager program can load itself instead of an operating system. Mostly famous boot-loaders are GRUB, LILO, and SYSLINUX. Bootloaders can recognize different operating systems such as Windows, Linux, Android, and BSDs.

  • With modern bios have UEFI which makes dual booting hard and difficult to install grub and if something went wrong the EFI partition becomes then it will become impossible to boot. There are some issues reported with Windows 10 update which caused many issues with dual boot.
