Can I erase a GRUB bootloader?

Question

I installed ubuntu on my Windows 7 pc. Automatically it used the GRUB bootloader. Then I learnt how to use VirtualBox. I have no need for Ubuntu. So can I delete Ubuntu and GRUB while leaving Windows 7 alone?

Answer 1

You cannot delete GRUB without then fixing the MBR on Windows 7.

Fixing the MBR:
The easiest way is to boot from the Windows CD/DVD.

* Boot from Windows CD/DVD and choose the "Repair" option
* Choose the command prompt
* Run the two commands
      o bootrec /fixmbr
      o bootrec /fixboot

If you've lost your original CD, get the live CD at http://www.hiren.info/pages/bootcd
You'll want to use the utility MbrFix 1.3

Answer 2

1. Boot your Windows 7 Installation DVD
2. Press a key when the message indicating "Press any key to boot from CD or DVD …" appears.
3. Select a language, a time and currency, and a keyboard or input method, and then click Next.
4. Click Repair your computer. In the System Recovery Options dialog box, choose your installation and click Next.
5. In the System Recovery Options dialog box, click Startup Repair.
6. If step 7 fails, click the Command Prompt and enter the command "bootrec.exe /fixmbr"
