    Remove Grub - Restore Windows 7


    You are dual booting with a Linux OS, using the Grub bootloader menu, and now you want to remove Linux and Grub and restore your Windows 7 boot manager.

    Here's how:

    This screen shot shows Windows XP, Vista, Windows 7, and my Ubuntu 9.10 installed on logical partitions (volumes) in an extended partition. The two partitions on the end are for Ubuntu and its swap partition. Windows does not recognize the file system used by Ubuntu, so you see no data.

    This is the same hard drive viewed from Ubuntu using GParted. Ubuntu does recognize the Windows NTFS file system and correctly labels the partitions. Again for verification, the last two partitions (volumes) are for Ubuntu and its swap partition.

    From Windows 7 Disk Management, remove (delete) the last two partitions or, if your installation is different, the Ubuntu partitions.

    Boot to your Windows 7 install DVD (or the System Repair CD) and navigate to the Command Prompt option.

    Type: diskpart
    and press enter.

    Type: select disk 0 (zero)
    and press enter

    Type: list volume
    and press enter

    and identify the drive letter of your CD/DVD drive.

    Code:
    Microsoft Windows [Version 6.1.7100]
    Copyright (c) 2009 Microsoft Corporation.  All rights reserved.
    
    X:\Windows\system32> diskpart
    
    Microsoft DiskPart version 6.1.7100
    Copyright (C) 1999-2008 Microsoft Corporation.
    On computer: VIRTUAL-7
    
    DISKPART> select disk 0 
    Disk 0 is now the selected disk.
    
    DISKPART> list volume 
      Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
      ----------  ---  -----------  -----  ----------  -------  ---------  --------
      Volume 0     D                       CD-ROM          0 B  No Media
      Volume 1     S   System Rese  NTFS   Partition    100 MB  Healthy
      Volume 2     E   Virtual-XP   NTFS   Partition     11 GB  Healthy    System
      Volume 3     C   Virtual-7    NTFS   Partition     20 GB  Healthy    Boot
    
    DISKPART> exit
    Type: exit
    to close Diskpart.

    Using the drive letter you identified, type: D:
    and press enter.

    Type: cd \boot
    and enter

    Type: bootsect /nt60 SYS /mbr
    and press enter

    This command should find the "Active" partition with the System files and boot code and restore your Windows 7 Boot Manager.

    Type: exit
    to close the Command Prompt
    then restart.

    If Windows 7 is the only OS, you should boot directly to it and not see any Boot Menu.
