How to Bypass Grub Rescue on a Linux Computer

In order to give Linux’s Grub/Grub2 bootloader access to your boot sequence and run a system entirely different from the original bootloader, the computer’s normal boot sequence must be bypassed or overwritten when Linux is installed. If something goes wrong during installation, the boot sequence may not be able to load when the machine restarts. Then Grub Rescue loads to assist with PC recovery. 

You are entirely locked out of your computer if you don’t know how to utilize this prompt, so don’t panic! You can overcome Grub Rescue with the help of this article. The default bootloader for systems based on the Linux kernel is the GRUB (Grand Unified Bootloader), a utility for booting and loading operating system kernels. Regular users seldom ever see GRUB in use, despite the fact that it starts up immediately when a computer is turned on. It runs automatically and doesn’t need any input from the user. On the other hand, if you try to boot another operating system at the same time as Linux on the same machine, the bootloader of the other system might overwrite GRUB, making it impossible for Linux to start.
