#title How To Easily Add A Boot Partition To An Existing System ||<
><>|| = Introduction = Some situations (eg BIOS limitations, or [[https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1030887|this GRUB bug]]) may require to '''create a separate /boot partition at the start of the disk, and setup Ubuntu to use it.''' Here is how to do it very easily: = Procedure = == Step 1 - Boot on a liveCD or liveUSB == Boot your computer either on: - a [[LinuxSecureRemix|Linux-Secure-Remix]] liveCD or liveUSB, then choose "Try Ubuntu", then go directly to '''Step 3 below'''. - or a Ubuntu live-CD or live-USB, choose "Try Ubuntu", then go to '''Step 2 below'''. == Step 2 - Install Boot-Repair in the live-session == Once in the Ubuntu live session, install [[Boot-Repair]] this way: * Connect internet * Open a terminal (Ctrl+Alt+T) and type : {{{ sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update }}} {{{ sudo apt-get install -y boot-repair }}} == Step 3 - Run gParted == Launch gParted from either: - the Dash (Ubuntu 11.04 and next): click the Ubuntu logo in the top-left corner of the screen, then type '''gparted''' and click on the '''gParted''' icon that will appear. - or System->Administration->gParted menu (Ubuntu 10.04) - or by typing '''gksudo gparted''' in a terminal == Step 4 - Create a 1GB partition at the start of the disk == Via gParted: - Reduce one of the first partitions of the disk in order to '''create 1GB (=1000MiB) of free space at the start of the disk''' where Ubuntu is installed. This free space must be located '''inside the first 100GB of the disk''' (its end must not be located at more than 100GB from the start of the disk). Important: to resize Windows Vista/7/8 partitions, don't use gParted but Windows tools instead. {{http://pix.toile-libre.org/upload/original/1342471488.png}} - In this free space, create a '''1GB partition formatted in EXT4'''. - On a paper, note the name of this new 1GB partition. This is generally something like /dev/'''sdXY''' (X is a letter, Y is a number). == Step 5 - Run Boot-Repair == Launch Boot-Repair from either: - the Dash (Ubuntu 11.04 and next): click the Ubuntu logo in the top-left corner of the screen, then type '''boot''' and click on the '''Boot-Repair''' icon that will appear. - or System->Administration->Boot-Repair menu (Ubuntu 10.04) - or by typing '''boot-repair''' in a terminal == Step 6 - Choose the right option == In Boot-Repair: - Click on '''Advanced Options''' - Go to the '''GRUB location''' tab - Tick the '''"Separate /boot partition: sdXY"''' option (sdXY must be your 1GB partition) {{http://pix.toile-libre.org/upload/original/1342472594.png}} - Click '''"Apply"''' - Note on a paper the URL ('''paste.ubuntu.com/XXXXXX/''') that will appear. - Shutdown the computer - Remove the liveCD and/or liveUSB - Start the computer. You should now be able to boot into Ubuntu. = Remarks = - '''if you need help''', please create your new own thread [[http://ubuntuforums.org/newthread.php?do=newthread&f=333|here]] (don't forget to indicate the URL you noted on your paper at Step6, this will give valuable information to understand your problem) = External Links = - [[http://ubuntuforums.org/showthread.php?t=2027546|Discussion thread on ubuntuforums for any question/comment about this tutorial]].
