This question already has an answer here:

I have a current working install of Ubuntu 13.10 64 bit that I am very happy with.

I need to install Windows 7 as a dual-boot, to give me the option of a launching Windows at boot time.

All the answers I can find are about installing Ubuntu after Windows.

Is this possible to do this without wrecking my Ubuntu Installation?

Any help appreciated

  • Yes, you can install Windows after Ubuntu without causing any damages to the Ubuntu installation.

  • All you have to do is create a separate ntfs partition for Windows on Ubuntu using Gparted Partition Editor, etc.

  • On the Windows installation, select the custom option to install Windows on the created ntfs partition.

  • Please note that the created ntfs partition would be a Primary Partition. Otherwise windows can't boot.

  • After windows is installed run Boot-repair.

Great - Thanks Avinash. Will that automatically set up a boot choice of OS's as well or do I have to set that up? –  user236869 Jan 17 at 14:52
    
After the windows installation was finished,you must ran boot-repair. –  Avinash Raj Jan 17 at 14:55
    
That doesn't really answer 236869's question. IDK what the answer is, but I'm sure that if you run sudo update-grub in your terminal, a Windows boot option will be added automatically. –  TSJNachos117 Jan 18 at 0:33
    
PS: If you can't boot Ubuntu after installing Windows, you can make it boot temporarily by using Super Grub Disk. That way, once you get Ubuntu running again, you can install/run Boot-Repair as a more permanent solution. –  TSJNachos117 Jan 18 at 0:40
    
@TS You are wrong.After installing windows,windows bootloader take over the grub,so you can't boot into Ubuntu.After that there might be two options to dualboot windows and Ubuntu.They are, 1.Easy BCD ,2.Boot-repair .If you run boot-repair after installing windows,boot-repair will reinstall grub2 on the first disk aka /dev/sda.If boot-repair fails to show windows option on the grub,then you boot into Ubuntu and run sudo update-grub command on the terminal.Now the windows entry on the grub menu list will be added. –  Avinash Raj Jan 18 at 1:21
