Depends on the CD you've got.
Standard Windows 95 CD's aren't bootable, so you need a boot diskette (with CD-support) to use them. You can download a program to make one from www.bootdisk.com; be sure to choose the right one.
Notebooks, however, often come with a ready-made recovery CD with all the drivers and custom software that isn't on a standard Windows 95 CD. That should boot, provided the BIOS is set to boot from CD first.
Even if you manage to install standard Windows 95 from a standard Windows 95 CD, it's doubtful you'll get it working in my opinion.
My son had this notebook given to him.
Running Win 95
Canon Innova Book 350 cd 100/540
I had it up and running,but when I put the cd-rom drive in to reinstall Win 95 nothing happens, now when I boot it up it will go to the windows startup screen and then the screen will say It is now safe to turn off your computer. I will take all the help I can get.
