Give dual boot the boot
Q: I installed Windows XP on a new hard drive in my PC, but I kept the old
drive containing Windows 98 SE as my D: drive. Windows XP apparently detected
the 98 SE operating system on the old drive and now offers me the choice of
dual-booting at start-up. How do I get rid of this option?
A: You'll need to edit the boot menu, which is controlled by the C:\boot.ini
file on your Windows NT, 2000, or XP boot drive. This small text file contains
various parameters that control the boot-up delay (Timeout=), the default
operating system, and information about which drive and partition contain your
two operating systems. Your current boot.ini file probably looks similar to
this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home"
D:\="Microsoft Windows 98"
To access the boot.ini file, click Start, right-click My Computer, select
Properties > Advanced, then click the Settings button under Startup And
Recovery. In the Startup And Recovery dialog, click the Edit button under
System Startup. This will open the boot.ini file with Windows' Notepad
program.
To open the file without the long string of dialogs (using Notepad or another
text editor), you must first remove the file's read-only attribute. To do so,
click Start > Run and type cmd. Click OK, and you'll see a command-line
dialog. At the command prompt, type CD\, then press Enter. Now type attrib -r
-a -s -h boot.ini (note the spaces between command letters and the hyphen for
the next letter) and press Enter. This will remove file attributes that would
prevent you from editing the file. Next, type notepad boot.ini and press Enter
to open and edit the file.
Now, to remove the Windows 98 boot option, simply delete this line:
D:\="Microsoft Windows 98." Without the line, Windows XP becomes the default
start-up OS. If you prefer to leave the dual-boot feature as is, but you want
Windows to start the default operating system sooner, simply replace the
number after Timeout= to something less than 30 seconds. (Windows will present
you with a dual-boot option, but it will launch XP within the time you
specify.) When you have completed your edit, save the file and close Notepad.
