I burned the operating system downloaded from the Internet onto a CD using the "Create Bootable CD" in NERO7.0, and set the BIOS to boot from the CD, but there was no response at all. How to make a self-bootable CD?

The downloaded image file may not be bootable.

The building owner needs to figure out whether it's a bootable CD or an autorun CD.

The Win98 CD I made can automatically run to the installation screen when inserted into the CD drive in a Win98 system. But when I set the first boot in BIOS to CD - ROM and then start the computer, I can't enter the Win98 installation screen. Is it that some files are missing? How should I make it?

The things you downloaded, when using NERO, you can just select the image file to burn. Hey, be more careful!

I'm sorry! I didn't make it clear. The file I downloaded shows as winrar, but actually an image file. I didn't know, so I extracted it, and after extracting, I deleted the original image file. Now there's only the extracted one on the computer. I want to know how to make a bootable CD - ROM in such a situation?

Of course, it won't work after decompression. The file after decompression is no longer the original disc image. However, you can make a bootable floppy disk, or download an img image of a bootable floppy disk, and then use ultraiso to load it into the iso file.

An image file containing CD - boot files, after decompression, the boot file is damaged. When burned into a CD again, the CD boot file cannot be burned into the boot sector of the CD, and it cannot become a bootable CD. This is because the original image file contains the boot sector record of the CD. But after decompression and then burning into a CD, the decompressed file cannot write this CD boot file into the boot sector of the CD. Therefore, it cannot become a bootable disk. So, the downloaded original image file cannot be decompressed; only the original image file can be directly burned into a bootable CD using burning software.
