So after I googled around I finally found a site that explains how to recover a grub2 from an installed Linux.

In my case Linux Mint 8 is using ext4 as root directory. Only a chroot to the target system is not enough. That was the clue that was missing in my many attempts to recover grub in MBR. Ubuntu installation on a system which already has other operating systems is simple. Ubuntu will automatically detect other operating systems already installed on the computer and enable booting into them from the grub boot menu.

However if you install Windows on a system which already has Ubuntu installed on a partition other than the partition on to which you install windows then you will.

Read about restoring Windows 10 bootloader from a working or faulty system with the command prompt. Recovering bootloader after installation of Linux, Ubuntu, Windows Often the reason for the operating system to fail when loading is the damaged bootloader Windows It happened again - this time on my Fedora machine!

This time the accident was caused by a simple dnf command:. I intended to remove dangling packages from my system - expecting my package manager to know which packages are needed and which not.

Unfortunately some really important packages amongst some legacy packages were removed. With Linux Mint Tara a Linux variant closely related to Ubuntu Bionic Beaver , the method both borked my installation, and made it possible later to save it. It arose out of my wanting a live USB having persistence, and since the time to install a utility like Unetbootin for a persistent install is roughly the same as a fresh install, I simply used the same live distribution to do an installation on the USB as was used to install the OS on the internal SSD.

This is where the new grub installation tangled with the internal drive. In most primary internal drive installs the partition's grub name is hd0, gpt1. Going into 'advanced', more than one kernel rescue was available. From there, run the grub utility and then boot normally. From this point, running the OS on the internal drive which was formerly inaccessible, unplug the USB, then run sudo grub-install.

When you reboot without the USB, you should be able to get back in. At this point the USB is configured to launch the internal drive into normal or rescue mode, and the drive has its own menu. Windows operating systems have the habit of installing their own bootloader on every installation - this wouldn't be a problem, if they would recognize all present operating systems. But unfortunately, they only recognize other Windows systems.

Insert the CD and boot from it. Open a terminal. If you have no idea what the name of your partitions is, use. Replace every following instance of that identifier with the one of your partition's identifier. Become root by typing.
