Rab,
This can occur if you have the /DEBUG switch in your boot.ini file. Follow
these steps to remove the /DEBUG switch:
1) Make sure Windows is set to Show All Files. To view protected operating
system files:
Double-click My Computer.
On the Tools menu, click Folder Options.
Click the View tab.
Click the "Show hidden files and folders" circle under "Hidden files and
folders".
Click to clear the "Hide extensions for known file types" check box.
Click to clear the "Hide protected operating system files" check box.
Click Yes when you are prompted to confirm your choice.
Click OK.
2) Find boot.ini on C:\
3) Right-click on the file-icon and choose Properties - uncheck the
Read-Only check box if it is checked, then click OK.
4) Double-click the boot.ini file, you should see text that looks like 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
Professional" /fastdetect /DEBUG
5) Remove the "/DEBUG" listing and any other "/" listings after ""Microsoft
Windows XP Professional" /fastdetect" *** WARNING - If you have a multi-boot
option, you may show more than one line under "[Operating systems]". Only
remove text on the line pertaining to the operating system you are booting
to. ***
6) Save the boot.ini file and close all Windows to desktop.
7) Reboot system.
Hope this helps.
