mbr_support.tar.gz is a compressed archive containing utilities and scripts to assist with Master Boot Record (MBR) tasks (backup, restore, analysis). Use only on systems you control and after verifying contents and integrity.
Inside the extracted directory, run:
sudo ./install-mbr /dev/sda
Or, if using the classic mbr package:
sudo /usr/sbin/install-mbr /dev/sda
This writes generic boot code that looks for an active partition. mbr support.tar.gz download
tar -xzvf mbr-support.tar.gz
