1) Start with a working 32 bit live CD of Ubuntu and choose "Try Ubuntu" - check to have a working Internet connection

(wired or wireless is the same)

2) Exec gparted and delete all partitions found. Re-run gparted to check it ok

3) open terminal (CTRL + ALT + T) and type:

sudo apt-get update; sudo apt-get install mbr; sudo install-mbr /dev/sda

4) reboot and install Windows normally from original installation CD/DVD

-------------------------------------------------------------------------------------------------------------------

From windows7, Install easyBCD.exe on your windows (you can find it at www.softpedia.com) Run it, and select RepairMBR,

And then delete some partitions were made by ubuntu's system.

-------------------------------------------------------------------------------------------------------------------

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.

-------------------------------------------------------------------------------------------------------------------

You can also boot the Ubuntu LiveCD and choose the "Try Ubuntu" option. After it loads, find and run gparted and remove the partition.

If Windows and Ubuntu are both gone and you want to reinstall Windows, you can repartition and reformat during the installation.

-------------------------------------------------------------------------------------------------------------------

• 1. Create a Ubuntu LiveCD/USB.

  2. Boot from your Ubuntu LiveCD/USB by selecting it in the BIOS boot options.

  3. Once Ubuntu loads, open a Terminal (Ctrl+Alt+T), and run these commands:

     1. sudo apt-get install lilo sudo lilo -M /dev/sda

     2. Note: you may have to replace /dev/sda with the main hard drive you installed Ubuntu and Windows to.

  4. You can then reboot into Windows.

-------------------------------------------------------------------------------------------------------------------

If you don't have a Windows recovery CD or you are constrained 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.

     1. 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.

• 1. Done!

-------------------------------------------------

• 1. Boot a live CD with Ubuntu

  4. Start the software and select what operating system you want to uninstall.

First download this tiny program into the Download directory.

press the windows key, type cmd.exe and on the result (The command prompt) start it as an "Administrator" by right clicking on the cmd icon, and select Run as Administrator.

In the new cmd.exe window, cd to your download directory. for example cd C:\Users\Lalu Patel\Downloads. _assuming your user name is "Lalu Patel".

  5. Now the former Ubuntu partition becomes an unallocated space.

  6. Select the left partition of the new unallocated space.

  7. Right click on the partition -> click on Extend Volume.

  8. Click on the Next button.

  9. Type in how many MB (1 GB = 1024 MB) you want to use from the unallocated space to extend the selected partition (step 5) into, then click on the Next button.see this.

NOTE: If you want to use all of the unallocated space to extend into, then type in the maximum available space shown for the unallocated space. 10. Click on the Finish button. you're done.
