Windows® 7 Boot Loader
Sometimes dual-booting can be very beneficial to try a new program, a latest Windows, or an application that needs to be run on a specific Windows platform. Other reasons to multi-boot may include replication of a client environment.
Windows manages dual-booting by using boot.ini file to display a menu of OS choices or partitions found on the current system. In Windows Vista and later versions of Windows, the bootloader was moved from boot.ini to a utility called BCD Edit.
If there is no data other than the OS installation to clean up the space change, the boot configuration by following these steps.
Note: Always ensure to back up any data that you want to keep before deleting or modifying partitions on VHDs. Your changes could make the partition unbootable.
To start the process, open the Start menu, select All Programs, and then choose Accessories. Right-click on Command Prompt and select Run as Administrator. Once you get into the command window, type bcdedit. This will display the existing running configuration of your Windows 7 Loader, showing any and all items that can boot on this system.
In this example, we are going to delete the entry for Windows 2008 R2 installation, as we wouldn’t need it for the time being. To remove an entry, you will need to know the boot loader Identifier.

One simple command will wipe out the Windows Server 2008 R2 entry out of the boot loader. At the command prompt, enter the following:
Press Enter, and the Boot Configuration Data Editor (BCDEdit) will clear the entry for the ID you specified and will display a message when completed. When Windows reboots, the only choice available in the boot menu should be the current Windows operating system.
