upgrading win95 to win98

Try renaming win.com to win.old or something like that. I believe that's the file the full install of Win98 looks for, and if it finds it, it'll tell you that you need the upgrade CD.

Load the CD in the drive and let it do a autorun,it will ask if you want to upgrade the system,answer yes and the upgrade should proceed.If you have to go to Run box,click on browse button,select CD-Rom letter and then make sure all files is listed,select the autorun file and click OK,then click OK again

This installation method is preferable over many I have tried. It will allow you to use an OEM disk to perform your upgrade without the "Operating System Already Exists" error.

1) Start your Windows 98 setup as normal, from within Windows95 (START, RUN, D:\SETUP.EXE).

2) When you are presented with the License Agreement dialog box, stop. Don't click anything yet. Do NOT click "NEXT." Just WAIT!!! Proceed to the next step.

3) Press CTRL + ESC to open the Start Menu and click "RUN."Type "NOTEPAD" and click "OK".

4) Open the file "SETUPPPP.INF" in the directory WININST0.400. This directory was created by the setup program.

5) Find the line in the file with the text "[data]". Add the following line after it: "OEMUP=1". The text should read as follows:

[data]
OEMUP=1

6) Save the file and exit Notepad.

7) Press ALT + TAB to return to setup and continue with your installation.

Note: In step 4, you can just go to C:\WININST0.400\SETUPPPP.INF file in EXPLORER and double click on it. NOTEPAD will automatically open the file to edit.

This method should allow you to perform your upgrade from your OEM disk with no problems. Good luck with your installation.
