GNU GRUB (Stands for GNU GRand Unified Bootloader) is a boot loader package. It is a part of the GNU project.

Steps to Solve Minimal BASH..GRUB Error

Step 1: Find the partition in which your Linux partition is stored. We can use the ls command to check for available partitions and their filesystem. Linux operating systems usually use ext2/ext3/ext4 filesystems.
grub> ls
This will show us all existing partitions. To Show All The Existing Partitions Note: If you don’t know which partition has Linux OS then you can check with the ls command as follows:
grub> ls (hdX, Y)
Here, X is disk number and Y is partition name. For Example: grub> ls (hd0, gpt3) or grub> ls (hd1, msdos5) Step 1 Step 2: After knowing the partition, set root and prefix variables:
  • root: Variable which points where the entire Linux OS is installed.
  • prefix: Variable which points where the GRUB is installed.
grub> set root=(hdX, Y)
grub> set prefix=(hdX, Y)/boot/grub
Step 2 Step 3: Install normal module and load it: normal: Linux mod file (linux.mod) used to load kernal. Command used to install mod : insmod
grub> insmod normal
Run this mod file the setup your GRUB:
grub> normal
Step 3 Step 4: Update GRUB. After entering your Linux OS, reinstall GRUB and update it. Open the terminal and enter following commands:
sudo grub-install /dev/sdXY
sudo update-grub
Here, X is disk number and Y is partition number of EFI partition. If you don’t know which partition is an EFI partition, use Disks or GParted to check. Step 4 Restart your PC and the Minimal GRUB error will be solved!!
