Fix Ubuntu Boot After Windows Install – Reinstall Grub In 5min – 11.04 Natty
The Quick Answer:
[Update: you may want to take a look at this first]
For version 1.99 (Ubuntu 11.04):
At a terminal in a LiveCD Desktop.
sudo grub-install --boot-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444/boot /dev/sda
Warning! This will not be the correct information for your PC!
You will need to replace ‘0d104aff-ec8c-44c8-b811-92b993823444’ and possibly ‘/dev/sda’ see below for details:
________________________________________
Overwriting the Master Boot Record
Note: The existing MBR will be lost. In order to dual-boot your computer, we will be creating a new Master Boot Record to include all operating systems, including Ubuntu Linux and Microsoft Windows.
1. Download the latest version of Ubuntu Desktop edition from http://www.ubuntu.com/GetUbuntu/download and burn your Ubuntu CD.
2. Reboot your computer and boot into a live session.
________________________________________
Find your Ubuntu boot partition
You need to mount the partition with the ‘/boot’ folder in it.
1. Mount your Ubuntu partition from the Places menu.
Open “Home” and click an unmounted partition from the bar to the left.
2. As an example: I clicked on a 16G partition to mount it, then I went into the boot/grub directory to check for grub.cfg
________________________________________
Note the partition details.
Run this command:
mount | tail -1
You should see output similar to this:
/dev/sda2 on /media/0d104aff-ec8c-44c8-b811-92b993823444 type ext4 (rw,nosuid,nodev,uhelper=devkit)
Note the designation for the disk /dev/sda which you will be using later, and the directory in /media.
Hint: Use Tab Completion in Terminal to complete the path.
This automatically finishes file names, directory locations, and other long or hard to type file names.
________________________________________
Verify that your partition is the Ubuntu boot partition.
Run this command:
ls /media/0d104aff-ec8c-44c8-b811-92b993823444/boot
or
ls /media/0d104aff-ec8c-44c8-b811-92b993823444
But substitute the example’s UUID, 0d104aff-ec8c-44c8-b811-92b993823444, with your volume’s UUID which you found earlier.
In either case, the output should be something like this:
abi-2.6.38-8-generic memtest86+_multiboot.bin
config-2.6.38-8-generic System.map-2.6.38-8-generic
grub vmcoreinfo-2.6.38-8-generic
initrd.img-2.6.38-8-generic vmlinuz-2.6.38-8-generic
memtest86+.bin
If what you have is not similar, unmount it and try another partition.
________________________________________
Reinstall GRUB
Now that everything is mounted, we just need to reinstall GRUB by specifying the correct directory and the correct drive name:
For version 1.99 (Ubuntu 11.04):
sudo grub-install --boot-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444/boot /dev/sda
If you get BIOS warnings try:
sudo grub-install --boot-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444/boot /dev/sda --recheck
Warning:
Substitute /dev/sda with the location you want to install GRUB on.
Substitute the example’s UUID, 0d104aff-ec8c-44c8-b811-92b993823444, with your volume’s UUID which you found earlier
If all went well, you should see something like this:
“Installation finished. No error reported”
________________________________________
Reboot and Test
Reboot, making sure to boot to your hard drive and not to the live CD.
Grub should be installed and both Ubuntu and Windows should have been automatically detected and listed in the menu.
The Master Boot Record will execute Grub as the initial boot-loader.
The Windows boot-loader is contained within the Windows partition and will then be chain-loaded by the Grub boot-loader.
If your GRUB Boot Menu is out of date, run this command:
sudo update-grub
________________________________________
Notes:
Prior to version 1.99:
sudo grub-install --root-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444 /dev/sda
If you get BIOS warnings try:
sudo grub-install --root-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444 /dev/sda --recheck
Warning:
Substitute /dev/sda with the location you want to install GRUB on.
Substitute the example’s UUID, 0d104aff-ec8c-44c8-b811-92b993823444, with your volume’s UUID which you found earlier

11.04 Natty – Mouse & Keyboard Tips
Keyboard Shortcuts
Launcher
- Hold Super – Invoke the Launcher.
Hold Super, then 1 or 2 or 3 and so on until 0– Open or focus an application. The number corresponds to the location of the icon on the launcher from top to bottom.Adding Shift will open a new instance of the application if it’s already open.- Holding the key is also useful when you want to get to the Launcher but do not want to invoke the Dash.
- Super–T – Open the rubbish bin/trash can.
Alt–F1 – Put keyboard focus on the Launcher, use arrow keys to navigate, Enter launches an application, Right arrow exposes the quicklists if an application has them.- Ctrl–Alt–T – Launch a terminal window.
- Super–A – Open Applications place
- Super–F – Open Files & Folders place
Dash
- Tap Super – Opens the Dash
- Alt–F2 – Invoke the Dash in a “special mode” to run a command. Typing in a Folder Name will find that folder in Nautilus, you can also use ~ as a shortcut in the field.
- The Dash opens with focus on the search box to find applications and files. Using the arrow keys will navigate the results, use Enter to launch.
Panel
- F10– Open the first menu on the panel, use the arrows keys to “scrub” across the menus. (There is no shortcut for the session menu, so hitting F10 and left arrow is a quick way to get there)
- Press Esc to close the menus without choosing anything.
Window Management
- Super–W – Spread mode, zoom out on all windows in all workspaces.
- Super–D – Minimize all windows; hitting it again restores them.
Window Placement
If you cycle through the same key Unity will cycle through different placement widths, so experiment by hitting the numkey multiple times, for example Ctrl-Alt-numpad 5 5 5:
- Ctrl–Alt–Numpad 7 – Place window in top left corner of screen.
- Ctrl–Alt–Numpad 8 – Place window in top half of screen.
- Ctrl–Alt–Numpad 9 – Place window in top right corner of screen.
- Ctrl–Alt–Numpad 4 – Place window on the left side of the screen.
- Ctrl–Alt–Numpad 5 – Center/Maximize the window in the middle of the screen.
- Ctrl–Alt–Numpad 6 – Place window on the right side of the screen.
- Ctrl–Alt–Numpad 1 – Place window in the bottom left corner of the screen.
- Ctrl–Alt–Numpad 2 – Place window in the bottom half of the screen.
- Ctrl–Alt–Numpad 3 – Place window in the bottom right corner of the screen.
- Ctrl–Alt–Numpad 0 – Maximize window.
Workspace Management
- Super–S – Expo mode (for everything), zooms out on all the workspaces and lets you manage windows.
- Shift–Alt–↑ – Expo mode for all windows in the current workspace only.
- Ctrl–Alt–← / → / ↑ / ↓ – Change to a new workspace.
- Ctrl–Alt–Shift–← / → / ↑ / ↓ – Place window to a new workspace.
- Ctrl–Alt–L – Lock the screen.
Screenshots
- PrtScn – Take a screenshot of the current workspace
- Alt–PrtScn – Take a screenshot of the current window
Mouse Tricks
Launcher
- Clicking and holding an icon and then dragging it around will allow you to reorder it on the launcher. You can also drag it off to the right of the launcher to move it around. Note that you need to make an explicit movement to the right to move the icon off the launcher before you can move it around.
- Dragging and Dropping an icon into the trash can will remove it from the Launcher. The program itself will remain installed and accessible through the dash.
- Scrolling the mouse wheel while over the Launcher scrolls the icons if you have too many and need to move around quickly.
Window Management
- Maximizing – Dragging a window to the top panel will maximize it.
- Restore – There are two ways to restore, or unmaximize, the topmost maximized window of the current monitor for this workspace (not using the window controls)
- Double clicking on the top panel (but not in the application’s menu)
- Dragging the top panel down.
- Middle click on Maximize – Maximize Window Vertically.
- Right click on Maximize – Maximize Window Horizontally
- Focus the topmost maximized window of the current monitor for this workspace: Left click on the top panel (but not in the application’s menu)
- Cycle between maximized windows of the current monitor for this workspace: Middle click on the top panel (but not in the application’s menu)
- Tiling – Dragging a Window to the left/right border will auto tile it to that side of the screen.
- Middle click on an application’s launcher icon – Open a new instance of the application in a new window. If the application isn’t running it will just open it normally.
Middle click on the top panel (but not the menu) – send the current window behind all other windows.

11.04 Natty – VirtualBox 4.0 Error “Failed to access the USB subsystem”
Fix from Ubuntu for Beginners!
Issue: User Privileges don’t get assigned correctly.
Open ‘Users and groups’.
Click ‘Manage Groups’ and look for the ‘vboxusers’ group.
Click properties.
Enable your account and reboot.
That fixed it for me but you may need this as well:
Users and Groups main window, click your username and then click ‘Advanced Settings’.
Go to the ‘User Privileges’ tab and scroll down to the bottom where you see this option.
Use VirtualBox virtualization solution
Make sure it is enabled. A reboot would be enough to make the error disappear now.
