Enabling a Dual-Boot System

Enabling a Dual-Boot System

Sometimes, it might be beneficial to have a single computer have the capabili- ty to boot more than one operating system so that you can save on purchasing additional hardware or when you want to test a new operating system. You can configure a computer to boot different copies of Windows, each of which is selected during a Windows boot menu.

If you want to have Windows 7 on the same system as Windows XP, you need to install Windows XP first while leaving room on the same drive or a differ- ent drive on the computer to install Windows 7. Then, install Windows 7 using the custom installation and select the partition on which you want to install Windows 7. Windows 7 automatically identifies your previous installa- tion of Windows (XP) and includes it in the boot menu.

To create a dual-boot system between Windows Vista and Windows 7 (or multiple copies of Windows Vista and Windows 7), the procedure is very sim- ilar to creating a dual boot system with Windows XP and Windows 7. One difference when you have a Windows Vista or Windows 7 installation is that you can use the Disk Management console (found as part of the Computer

Management console) to shrink a volume if you have free disk space on the volume you want to shrink. It is usually recommended that you defrag the hard drive first. Then right-click the volume you want to shrink and select Shrink Volume. After you’ve allocated the desired amount of space, click the Shrink button. Windows creates a new partition out of the free space you’ve allocated, all without even having to reboot. Of course, because this is a major change to the system, you should make sure that you have a good backup of your data before shrinking the volume.

You can also modify the default operating system and the time the list of oper- ating system appears by right-clicking Computer, selecting Properties, click- ing Advanced system settings, selecting the Advanced tab, and clicking the Settings button in the Startup and Recovery section. You can also specify what type of dump occurs during a system failure.

Cram Quiz Answers

1. E is correct. You cannot upgrade Windows XP or Windows 2000 Professional to Windows 7 Home Premium. Therefore, A, B, C, and D are incorrect.

2. B is correct. When you want to determine system compatibility with Windows 7, you should run the Windows 7 upgrade Advisor. Answer A is incorrect because it does not check hardware compatibility. Answer C is incorrect because Windows update does not specify if a device is compatible with Windows 7. Answer D is incorrect because updating drivers in Windows XP does not specify if a device is compatible with Windows 7.

3. B is correct. bcdedit is a command-line tool for managing BCD stores. It can

be used for a variety of purposes, including creating new stores, modifying exist- ing stores, adding boot menu options, and so on. Answer A is incorrect because System Configuration is used to manage startup programs and services. Answer

C is incorrect because the Computer Management Console includes multiple management tools including the Disk Management MMC, but it does not have any tools to manage the BCD stores. Answer D is incorrect because the Windows Boot Manager is a Windows boot component. It is not a console or tool to configure the Windows BCD stores.
