Search for Linux systems on all hard disk partitions, reinstall Grub method

The computer hard drive (non-VMware) installs Ubuntu, Fedora, Debian, OpenSUSE, LinuxMint, Mageia, Elementaryos, Pearos, Zorinos, Bodhi, Manjaro, Sparky, Linuxdeepin and other 13 Linux distributions, the Long march of the Linux version finally took the first step! But the problem comes, I like Zorinos grub to start the GUI, but the last installation of the Pearos ugly text interface to cover, how to do? For a long time, there was no satisfactory answer. Today accidentally installed KDE-CONFIG-GRUB2 and Grub2-common to Zorinos, found that grub automatically changed back to the kind of zorinos. So the clues, finally found the answer,

sudo update-grub2sudo GRUB-INSTALL/DEV/SDA

These two commands, exactly one to meet my requirements: 1, search all hard disk partitions on the Linux system. 2. Install the Grub interface for the current system.

After Linuxdeepin, Pearos and other system testing, tried!

Note: The above is used GRUB2, if it is grub, you should use the following command (ArchLinux applies):

Grub-install--force/dev/sdagrub-mkconfig-o/boot/grub/grub.cfg
