Adding SafeBoot to the Boot Menu

You can add Safeboot as an option to the normal XP boot screen

Open a command prompt

Copy the current c:\boot.ini to another name (just in case)

With your favorite text editor, edit c:\boot.ini

Copy then edit the current boot line to another line. For example:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
might copy and then change to:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional Safeboot" /fastdetect

Start MSCONFIG

Click on the BOOT.INI tab

Highlight the second line with the additional name of Safeboot

Check the /SAFEBOOT box with option you want

Minimal - Minimal set of drivers
Network - With Network Support
Dsrepair - Directory Services Repair
Minimal (Alternate Shell) - Standard Explorer Desktop

You will now have this option every time you start XP
