I have a laptop which was Linux/Windows 7 dual-boot. I need to get rid of the Linux partition so that it only boots into windows.

I know how to do this if I have the Windows 7 CD(which I do). But this laptop does not come with a CD drive.

Is there anyway to do this without using the CD?

Do the following

  1. Start a cmd shell running as administrator (Start / Search / cmd / right-click Run as Administrator)
  2. Type bcdboot c:\windows

That will re-write the MBR and so remove grub and re-install the Windows loader.

Is it possible to run bcdboot from linux or using vm ... – rzr Aug 24 '13 at 12:23

A very easy solution would be to download and install Visual BCD Editor.

The tool comes with "Dual-boot Repair" utility. Run it and click "Automatic Repair". Confirm.

That's it ! You can reboot to Windows 7.

Explanation: The automatic dual-boot repair will (re)create Windows 7 MBR and PBR (master and partition boot record) and reset/repair the Boot Configuration Data (BCD) store to default values (e.g. timeout 30 sec., Windows 7 as default loader).

How to create a bootable Windows 7 USB/DVD

No CD but always a USB

If this option is not good trying looking into any other USB booting ways.

That's the only way ... MBR cannot be fixed while it's active.

Making a bootable USB flash storage is good idea but it is not only way. – kamae Dec 13 '11 at 13:59
    
@Kamae... I'm sorry but I answer to the Original Poster... His case... he doesn't have a CD ROM drive so the only possible way is to do it with a flash drive... The other option would be to plug in a CD drive... So it comes to the same... Find me an other way and I will accept that you put minus -1 to my answer... Don't just minus my answer for now "apparent" reason... The answer is for the original poster not for general answer... – pSyToR Dec 20 '11 at 10:21
    
@Kamae... It would be nice when you "flag" an answer... To actually explain properly WHY... Since Windows 7.. Like Paul Said a bit higher here the BCDBoot.exe is a new thing from Windows 7 that let's you re-write the MBR ... Nice blog about it : hanselman.com/blog/… – pSyToR Dec 22 '11 at 5:30

What you need is a bootable flash drive with the Windows Recovery Disk installed to it. Tom's Hardware has a nice write-up on what you need to do. If you have another computer with a DVD drive, that'll make it easier to create the flash drive, otherwise you'll have to download a torrent of the image. In either case, a second computer with Windows 7 already installed is necessary.
