If things get messed and nothing boots, you can use the Rescatux live CD too. It can restore/fix as far as I know both boot loaders, haven't tried for windows one yet.

just wondering because i managed to delete ubuntu from easy bcd but it will not allow me to format my dive in the disk manager its a non named drive and when i write click it just give me the option to view the help


To remove Ubuntu, you will need a Windows Recovery CD or Installation CD, or a Ubuntu Live CD.
Note: If you don't have a Windows Installation or Recovery CD available, you can download the Windows 7 ISO file here. You cannot install Windows with a genuine Purchased Product Key though, as these ISO files are 100% legal and will only install as an Evaluation copy for 30 days without a product key.
To remove GRUB:
  1. Grab a Windows recovery media or installation CD and boot from it. You should see this on a recovery media.
    enter image description here
  • You should see this on an installation media. Click "Repair your computer" and you should see a screen like the first image. Image from bleepingcomputer.com
  1. Open the Command Prompt, then type bootrec /fixmbr into the Command Prompt. enter image description here
  2. Reboot and boot into Windows. Then follow the steps below to remove the Ubuntu partitions.

If you don't have a Windows recovery CD or you are too lazy to download and burn the ISO files mentioned before, you can use Boot-repair. It is a tool that fixes most boot problems(Windows or Ubuntu). I suggest using a Windows CD if possible.
To use boot repair:
  1. Boot from a Ubuntu live CD or USB
  2. Type these lines in the terminal one line at a time.
    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install boot-repair
  3. Search for Boot-Repair in the Dash and launch it.
enter image description here
To fix your computer with Boot-repair, simply click the "Recommended Repair" button. Then follow the steps below to remove the Ubuntu Partitions.

To delete the Ubuntu Partitions:
  1. Go to Start, right click Computer, then select Manage. Then select Disk Management from the sidebar.
  • enter image description here
  1. Right-click your Ubuntu partitions and select "Delete" . Check before you delete!
  2. Then, right-click the partition that is on the Left of the free space. Select "Extend Volume". Go through the Wizard and Finish it. enter image description here
  3. Done!
Another note from Tanner: If you are using an extended partition, you might have to remove the big extended partition to make the space unallocated.


  1. Boot a live CD with Ubuntu
  2. Choose "Try Ubuntu"
  3. Download and install OS-Uninstaller.
  4. Start the software and select what operating system you want to uninstall. os-uninstaller-fr
  5. Apply
  6. When all is over, reboot your computer, and voila, only windows is on your computer!
          You can go into the Disk Management utility and delete the Ubuntu partition. Right click My Computer, select Manage, Disk Utility. Once you delete the partition, right click My Computer, select Properties and go to the Advanced tab. Go into the Start Up and Recovery, set Windows as the default operating system and set the Time to display the list of operating systems to 0 and click Ok.

 Windows Dual boot

Introduction


This page describes how to set up your computer in order to dual boot Ubuntu and Windows.

Back Up Your Data


Although this may seem obvious, it is important to backup your files to an external backup medium before attempting a dual-boot install (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose.

Have a Windows recovery CD/DVD available


Some computer manufacturers that pre-install Windows provide a Windows recovery/re-installation CD or DVD with the computer. However, many companies no longer ship a physical disc but instead create a hidden partition on the hard drive in which the recovery-disk information is stored. A utility is then usually provided which allows the user to burn a recovery/re-installation CD or DVD from it. If you are buying a new computer and intent on dual-booting, make sure you have (or can make) a physical Windows recovery/re-installation CD or DVD. If neither a CD/DVD nor a recovery partition/burning utility is provided by your computer manufacturer, you may need to telephone your vendor and ask for a CD or DVD (to which you are normally entitled under the Windows EULA).

Getting Recovery Media


You may need to request a physical recovery/re-installation CD or DVD directly from your computer manufacturer. Here are some resources:
Once you have created a physical backup disc from a restore-image partition on the hard-drive, the restore-image partition can either be removed or left in place. Ubuntu can be installed with it intact without problems.
Alternatively, if you own a licensed copy of Windows Vista or Windows 7, you may download a system recovery CD that may be used to access a recovery console free of charge from NeoSmart Technologies. This CD can't be used to reinstall Windows in case things go majorly wrong, but it does contain the needed tools to set boot-related issues right.

Install Ubuntu after Windows


A Windows OS should be installed first, because its bootloader is very particular and the installer tends to overwrite the entire hard drive, wiping out any data stored on it. If Windows isn't already installed, install it first. If you are able to partition the drive prior to installing Windows, leave space for Ubuntu during the initial partitioning process. Then you won't have to resize your NTFS partition to make room for Ubuntu later, saving a bit of time.
When a Windows installation already occupies the entire hard drive, its partition needs to be shrunk, creating free space for the Ubuntu partition. You can do this during the Ubuntu installation procedure, or you can see How to Resize Windows Partitions for other options.
If you have resized a Windows 7 or Vista partition and cannot boot up windows, you can use the instructions from WindowsRecovery to fix it.

Install Ubuntu


  • Download an Ubuntu LiveCD image (.iso) from Ubuntu Downloads and burn it to a disc (see BurningIsoHowto).
  • Insert the LiveCD into your CD-ROM drive and reboot your PC.
  • If the computer does not boot from the CD (e.g. Windows starts again instead), reboot and check your BIOS settings by pressing F2, F12, Delete, or ESC. Select "boot from CD".
  • Proceed with installation until you are asked this question: "How do you want to partition the disk?".
  • If you have already partitioned the disk and left space for Ubuntu, install it to that and then follow the rest of the steps.
  • Otherwise, choose one of the next two steps.

Automatic partition resizing (recommended)


  • Choose the first option, which should say "Install them side by side, choosing between them each startup".
  • Specify the size of the new partition by dragging the slider at the bottom of the window.
  • Click on "Forward".

Manual partitioning


  • Choose "Manually edit partition table".
  • Listed will be your current partitions.
  • Select the partition you want to resize and press Enter.
  • Select "Size:", press Enter.
  • Select Yes, press Enter.
  • Type in a new size in gigabytes for your partition, it's recommended you free up at least 10 GB of free space for your Ubuntu install. Press Enter when happy with your changes. It may take some time to apply the changes.
  • Create a swap partition of at least your amount of RAM (if you don't know, 2000 MB is a good value).
  • Create a partition for your Ubuntu installation.
  • Select "Finish partitioning and write changes to disk".

Master Boot Record and Boot Manager


GRUB2 is the boot manager installed in Ubuntu by default. If you use the Alternate CD you can choose GRUB or Lilo instead. GRUB2, GRUB and Lilo are open source boot managers that install the main parts of the boot loaders inside Ubuntu. This means Ubuntu is independent and avoids any need for writing to other operating systems. To accomplish this, the only thing in your computer outside of Ubuntu that needs to be changed is a small code in the MBR (Master Boot Record) of the first hard disk. The MBR code is changed to point to the boot loader in Ubuntu. You will be presented with a list of operating systems and you can choose one to boot. If you do nothing the first option will boot after a ten second countdown. If you select Windows then GRUB or Lilo will chain-load Windows for you at the Windows boot sector, which is the first sector of the Windows partition.
If you have a problem with changing the MBR code, you might prefer to just install the code for pointing to GRUB to the first sector of your Ubuntu partition instead. If you do that during the Ubuntu installation process, then Ubuntu won't boot until you configure some other boot manager to point to Ubuntu's boot sector. Windows Vista no longer utilizes boot.ini, ntdetect.com, and ntldr when booting. Instead, Vista stores all data for its new boot manager in a boot folder. Windows Vista ships with an command line utility called bcdedit.exe, which requires administrator credentials to use. You may want to read http://go.microsoft.com/fwlink/?LinkId=112156 about it.
Using a command line utility always has its learning curve, so a more productive and better job can be done with a free utility called EasyBCD, developed and mastered during the times of Vista Beta. EasyBCD is very user friendly and many Vista users highly recommend it.

Installing Windows After Ubuntu


Normally when Windows is installed after Ubuntu the "Master Boot Record", MBR, will be overwritten. You can bootup off a LiveCD and repair the MBR. However, there are 2 different approaches:

Recovering GRUB after reinstalling Windows


Please refer to the Reinstalling GRUB2 guide.

Master Boot Record backup and re-replacement


Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code:
  1. Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with)
  2. Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1
  3. Install windows
  4. Boot into a LiveCD
  5. Mount your root partition in the LiveCD
  6. Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1
  7. Restart and Ubuntu will boot
  8. Setup grub to boot windows

Issues with Windows XP and NTFS


The Ubuntu installer has included support for resizing NTFS partitions since Ubuntu 5.10 (Breezy Badger) was released way back in 2005. Very few problems have been reported relative to the huge number of times that the installer has been used. If you tried the above procedure and have had no luck, it might be that there is a pre-existing problem either in the file system, in the partition table or the hard disk.
First you should try running CHKDSK before trying again to resize the partition, and if you are using the Alternate CD, defragging might help. It is recommended that you run CHKDSK once again after resizing your NTFS partition.
Also, try the following alternative methods:

Using QtParted from the System Rescue CD


  1. Boot into Windows and backup any valuable documents/photos etc onto removable media such as CD-R/DVD-R.
  2. Run the Windows disk check tool (Error-checking) on C: a couple of times (the results can be seen in the Administrative Tools > Event Viewer > Application under a "Winlogon" entry).
  3. Run the Windows defragmentation tool on C:
  4. Download the System Rescue CD ISO image (321 MB; has several very useful software tools).
  5. Burn the ISO image to a CD.
  6. Boot from the CD and hit Enter when you see the message "Boot:".
  7. When you get a command prompt, enter:
run_qtparted

  1. Select your disk on the graphical screen (most likely /dev/hda).
  2. Select your NTFS partition to be resized (most likely /dev/hda1).
  3. Right click with the mouse and choose Resize.
  4. Set the new partition size.
  5. Commit your changes in the File -> Commit menu. If your keyboard and mouse stop responding during resizing then please just be patient.
  6. Once your changes are saved, remove the System Rescue CD and insert your Ubuntu installation CD.
  7. Reboot and install Ubuntu into the free space.

Using GParted from UNetbootin-PartedMagic


Another approach to resizing partitions, which does not require a CD, is to load PartedMagic from Windows via the UNetbootin PartedMagic Loader:
  1. Download and install the Windows (.exe) file, then reboot.
  2. Select the UNetbootin-partedmagic entry after rebooting, and wait as PartedMagic boots up.
  3. Start the partition manager by clicking the GParted icon on the the panel.
  4. Select your disk (probably /dev/sda) via the drop-down menu on the top-right corner of the interface.
  5. Right-click the NTFS partition to be resized (probably /dev/sda1), and select the "resize" option.
  6. Drag the slider to specify the new size the NTFS partition should be resized to, then press OK.
  7. Press the "Apply" button to resize the disk, then reboot once done.
  8. Upon the next Windows boot, click OK when prompted to remove UNetbootin-partedmagic to remove its boot menu entry.
