How to install Windows 7 over pre-installed Ubuntu 12.04?

Sudeepto Dutta September 20, 2012

Well currently I am using Ubuntu 12.04 only. Yes, I am not dual-booting it with Windows, since my hardware is not up to the mark.

But now I am upgrading my PC, so I want to install Windows 7 over Ubuntu 12.04 for driver installation & other stuff. After that I will dual-boot Ubuntu 12.04 (or maybe 12.10 who know :) )

Anyways, please tell me how to replace Ubuntu 12.04 with Windows 7.

Also, can someone tell me if there is a tool so that I can make my USB drive bootable with Windows 7 on my Ubuntu 12.04?

Please help ASAP!

    if you have 2 separate or partitioned hard drives install windows on the other drive, then the Master Boot Record will be overwritten, then if you want to recover GRUB, here is a guide.

    If windows is installed after ubuntu or any other linux the MBR will be overwritten & linux will not be accessible. It is advisable to install ubuntu over windows to make dual boot...

    Well If you have a unused partition in the hard disk. Simply install win7 in that partition. You will also need to install Easy BCD from as boot manager to access both win7 & ubuntu 12.xx from boot menu.

    BTW why you want to change to Win7, Ubuntu is a fantastic OS?

      Yes I know UBUNTU is fantastic sir but I recently upgraded my PC so I am running windows 7 as I need to run some applications that are only windows specific & Ubuntu can't run them even with wine...

      BTW than for your response sir :)

    There's no magic trick here: just install Windows 7. Leave some space for Ubuntu later, but if you don't Ubuntu will be able to make space for itself. Good luck.

    I recommend first install windows 7 and then install ubuntu 12.04, you will be asked to create the partition to create ext3 and swap partition when installing ubuntu after installing windows 7, it has option to create partition automatically for swap and ext3. Just select those option and go through the steps. After restarting your PC your pc will load the grub boot loader the built in boot loader of ubuntu, which will show option to choose either windows 7 or ubuntu to boot from. In this way it becomes easy to use both win7 and ubuntu together, if you prefer to install ubuntu over windows 7. As ubuntu is smart which can easily detects your current OS and it is shown in boot menu.

    boot up from a windows disc. and then select the drive you want to use and windows will ask to format it to a windows friendly HDD format. do the format then after that, if you want create partitions as you want! :)

    if you want to delete ubuntu and install windows 7, just boot the windows 7 DVD. And install with the settings you want.

    The easiest way is to do the other way round.

    1. Backup your data files.
    2. Install windows 7, delete all existing partitions and create two partition, one is for windows and the other for ubuntu. Do this process during the installation process of windows 7.
    3. Start windows 7, go to the ubuntu website, and install ubuntu via the WUBI installer (windows installer) to the other partition created.

    Now you have both the OS in a dual boot environment. It is pretty simple actually so Njoy!!! :)

    What the first response is saying is probably the easiest way to do it. Be careful though if you are doing it from an Upgrade CD the "custom install" will not flag your installation odd and your key may not work.

    If you want to REPLACE the existing OS with Win7, just boot the Win7 DVD. At the drive selection page, delete any existing partitions you don't want and allow Windows to use that newly freed space for your Win7 installation.If you will want to install another OS at a later time, you may wish to create a new partition for Win7 of whatever size you like and keep some unpartitioned space for the other OS. This will save time for the installation of another OS since you will not need to mess around with shrinking an existing partition to make room for the new OS.

      Thanks for replying sir...

      But since I have given .ext4 as partition format for UBUNTU , do you think windows will be able to detect it ..??

      Because once when I dual booted ubuntu & windows 7 , whenever I used win 7 the ubuntu partions were never visible ..
