I can not read the product number even using a magnifying glass....

It is an HP Pavillion Windows 7.

I appreciate your response as I've tried each F# plus more things that I read on line.

It did boot once a long time ago using the windows 7 CD that was purchased but not this time.

Help!  Thanks...Karen

Model number could be 15-cf(0079nr

Am using an external CD drive.

This is a windows 7

hi

sorry, I replied when I had read this mentioned in your message

"Operating System: Microsoft Windows 8.1 (32-bit)  "

https://support.hp.com/ie-en/document/c06046872

finally mentioned originally with windows 10!
So you had already done what is recommended, probably to install windows 7?
What do you want to do now finally?

shut down the computer completely
restart with the cd in the drive, and immediately hit the escape key
do you have the menu as mentioned here?

Appreciate your trying....thanks so much!

Didn't work, (the escape pressing at second intervals) at startup) tried over 5 times.

Also tried some of the other Fs with the seconds pressing...

Had held and also tried one press on all of the others.

Have spent hours on this as you are spending lots of time.

That should have been the answer!!!  Again thanks.  Karen
