Using the Ubuntu CD (Recommended)

This page documents how to restore or recover the boot-loader (GRUB) after installing Windows. Some reasons to repair your boot-loader might include installing Microsoft Windows after you have installed Ubuntu, adding or removing a hard drive, or changing hard drive settings.

I'm trying to dual boot ubuntu 11.04 with windows 7. In the installer, there's supposed to be a 'run alongside something else' option for dual booting. However, it says that no operating system are. Check it out:Khaos to your skype: kha. I'm saying that NORMALLY if you dual-boot and windows gets fucked up (by something ELSE) then the linux install can still work. With Wubi they're both on the same partition, so if windows dies linux might die too (depending on what happened). To install Ubuntu Linux on your computer, you'll first need to create an installer by placing the Ubuntu ISO file on a disc or flash drive. If you use a DVD, a standard 4.5GB disc will be plenty. If you choose to use a flash drive, make sure it is at least 2GB. Download the Ubuntu Linux ISO file. 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.

Note: this tutorial does not apply if you had installed Ubuntu inside Windows (via the Wubi installer). In this case, please read this page.

The graphical way

Insert your Ubuntu CD, reboot your computer and set it to boot from CD in the BIOS and boot into a live session. You can also use a LiveUSB if you have created one in the past.
Install and run Boot-Repair
Click 'Recommended Repair'.
Now reboot your system. The usual GRUB boot menu should appear. If it does not, hold Left Shift while booting. You will be able to choose between Ubuntu and Windows.

The terminal way

How To Install Ubuntu 11.04 On Windows 7 Dual Boot

* Open a terminal. As of Ubuntu 11.10 and 11.04, this can be done by opening the Unity Dash (you can click the Ubuntu logo in the top panel or use the Windows key on your keyboard) and typing in 'Terminal', and clicking what comes up. On earlier versions, you can achieve this by going to Applications -> Accessories -> Terminal. Alternately use the Keyboard Shortcut: CTRL + ALT + T.

You are then presented with a standard bash prompt, type - this only works to reinstall to MBR of a working system:

where XXX is the device of your Ubuntu install. (eg: grub-install /dev/sdb). Hint: You can also use /dev/disk/by-label/ if the partition you installed on has a label. You can determine the /dev node for such a device by running:

This will give the output of something like:

You can also use fdisk if you do not see the /dev/disk/by-label:

From here, find only the drive name, ignore the partition number Windows 7 32 bit free download. , that is, for partitions labeled 'root', 'data2', 'fat', 'home' and 'swap' it's all still just sda. This is due to the fact that GRUB is installed in the MBR of the drive, and not on a partition.

Trouble? If other things are messed up, e.g. if you have deleted the partition from where Grub was previously installed, grub-install may return an error message such as 'cannot find a device for /.. (is /dev mounted?)'. You may have to do grub-install a bit differently. Refer to the handy guide on fixing a broken system

Now reboot your system. The usual GRUB boot menu should appear. If it does not, hold Left Shift while booting. You will be able to choose between Ubuntu and Windows.

Boot your system from the Ubuntu Alternate CD.
When the Ubuntu splash screen comes up with the boot: prompt, type in rescue and press enter.
Choose your language, location (country) and then keyboard layout as if you were doing a fresh install.
Enter a host name, or leave it with the default (Ubuntu).
At this stage you are presented with a screen where you can select which partition is your root partition (there is a list of the partitions on your hard drive, so you are required to know which partition number Ubuntu is on). This will be dev/discs/discY/partX, where the X is a partition number and Y is the number of the drive.
Now proceed as described in 'The terminal way' above.

Procedure

Some situations (eg BIOS limitations, or 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:

Step 1 - Boot on a liveCD or liveUSB

Boot your computer either on:

- a 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 :

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.

- 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.
