I was using first the win 98, then upgraded to windows xp prof.
edition as a second operating system in my pc.
My question how can I uninstall win 98 and keeping only the xp without
formatting the hard disk or without affecting the stability of the xp
system ?

All of the following should be done in Windows XP.


Go to Start, Run, and type:
cmd

In the box that appears, type the following commands:
attrib -s -h -r C:\boot.ini
start C:\boot.ini
exit

(where "C" is replaced by the letter of the drive you boot from, if
necessary.)

A new window will have popped up at the second command. Look at the
section after [operating systems]. One of the lines will contain the
words "Windows XP". Leave it. Delete the other line (it probably will
be labeled MS-DOS.)


Now, go delete your \Windows folder -- but take the following
precautions!

1. Make sure you don't delete the one Windows XP is in (probably
\winnt on your drive)!

To find out where Windows XP is installed, go to Start, Run, and type
%systemroot% ; it should open the folder C:\winnt or wherever Windows
XP is installed, but it won't show you any files for your own safety,
which would make it hard to delete anything anyway.

2. You might want to backup or move your "Profiles" folder or your
"AIM95" folder in the Windows folder first; if you use AOL Instant
Messenger, put AIM95 in your new Windows folder, and just move your
Profiles folder to your Desktop or \ folder for safekeeping. THe
Profiles folder is particularly important if you save stuff to your
desktop a lot, as your users settings including desktop items are
contained within.

3. In fact, to be on the safe side you can just delete all the files
(but not the folders) in the Windows folder, and also remove the
System and System32 folder (also in the Windows folder), as well as
the Options folder if it's there (again in the Windows folder)-- again
make sure you don't confuse this with where Windows XP is installed,
as that would be Bad. This will free up most of the space used by core
of the operating system without touching anything potentially
valuable.


It's that simple. Sure, even after you're sure it's safe and you get
rid of the \Windows folder there'll be a few files remaining on the
drive that are unnecessary (if you want to be really compulsive about
deleting files, I can tell you what else you need to remove) - but
these'll take up less than a tenth of a megabyte, or in simpler terms,
less than a tenth of a floppy disk.

Good luck with your new OS!
