REMOVING WINDOWS VISTA FROM YOUR SYSTEM
1. If you installed Build 5048 as a standalone operating system on its own PC, then simply reformat the hard drive it is on.
2.
If you have Dual Booted with another operating system, for example Windows XP, then boot into Windows XP and go to Disk Management (right click My Computer>Manage>Disk Management).
Select the drive you have Windows Vista installed on, right click it and select Format. A quick format should be all you need.
2.
Proceed to and use the Quick Removal Method below.
3. If you have Windows Vista installed on a system with multiple operating systems, i.e. two or more in addition to Windows Vista, use the Complete Removal Method.
QUICK REMOVAL METHOD
Go to the Run dialogue box on your start menu and type “msconfig” (without the quotes). This will open the System Configuration Utility. Then go to the BOOT.INI tab and select "Check All Boot Paths".
This is automatic and all you need to do after this is select “OK” and “Apply” and "Restart".
On restart, place a check in the System dialogue box that pops up.
Note: This method while easy to use and effective has its shortcomings. It does not carry out a full cleanup of your system and leaves traces of the Longhorn installation on your Windows XP system drive. These will however not interfere with your Windows XP installation. Should you wish to fully remove Windows Vista from your system, use the Complete Removal Method.
COMPLETE REMOVAL METHOD
With Windows Vista still fully installed, boot to your Windows XP installation. Go to Start>Run and type "C:\boot\fixntfs -XP" (without the quotes) and click OK. Restart your system.
When the system reboots you will notice that the Windows Vista bootloader no longer exists.
Boot into Windows XP again and go to Disk Management (right click My Computer>Manage>Disk Management).
Select the drive you have Windows Vista installed on, right click it and select Format. A quick format should be all you need.
Now go to Windows Explorer and delete the following files from the root of your Windows XP installation hard drive or partition:
Boot (folder)
Boot.BAK
bootmgr
BOOTSECT.BAK
Right click My Computer, select Properties>Advanced>Startup and Recovery>Settings and under System startup, make sure that Windows XP is selected as the Default operating system. If not, then select it as Default operating system and select OK at the foot of the Startup and Recovery user interface and again select OK at the foot of System Properties user interface.
(Modifying the contents of one’s boot.ini file and bootsector may lead to not being able to access the operating system. Only experienced user’s comfortable doing so should use this method).
Return to My Computer, select Properties>Advanced>Startup and Recovery>Settings and this time select Edit. In the Notepad file that opens, select and delete all lines mentioning Windows Vista and then in that Notepad file, go to File and select Save.
Close Notepad and select OK at the foot of the Startup and Recovery user interface and again select OK at the foot of the System Properties user interface.
To confirm that your boot.ini file is now correct, go to the Run dialogue box on your start menu and type “msconfig” (without the quotes). This will open the System Configuration Utility. Go to the BOOT.INI tab and select "Check All Boot Paths".
You should get a dialogue box appearing with the message “It appears that all BOOT.INI lines for Microsoft operating systems are OK”. Restart your system
