<emphasis>GRUB</emphasis> (GRand Unified Bootloader) is more recent. It is not necessary to invoke it after each update of the kernel; <emphasis>GRUB</emphasis> knows how to read the filesystems and find the position of the kernel on the disk by itself. To install it on the MBR of the first disk, simply type <command>grub-install /dev/sda</command>. This will overwrite the MBR, so be careful not to overwrite the wrong location. While it is also possible to install <emphasis>GRUB</emphasis> into a partition boot record, beware that it is usually a mistake and doing <command>grub-install /dev/sda1</command> has not the same meaning as <command>grub-install /dev/sda</command>.
<emphasis>GRUB</emphasis>‏ (Grand Unified Bootloader ، أو مُحمِّل الإقلاع الموحد الكبير) هو محمّل إقلاع أحدث. لا يشترط استدعاؤه بعد كل تحديث للنواة؛ إذ أن <emphasis>GRUB</emphasis> يعرف كيف يقرأ نظم الملفات ويعثر على القسم الذي يحوي النواة على القرص وحده. لتثبيت <emphasis>GRUB</emphasis> على MBR القرص الأول، فقط اطبع <command>grub-install /dev/sda</command>. <indexterm><primary><command>grub-install</command></primary></indexterm>
