Booting to a CD on a computer or laptop is very useful especially no most installation disks are CD based, but older computers, with older bios options, may not support this
New bios[]
You can try to flash your bios to a new one.
With floppy[]
One solution is to make a floppy disk boot disk. This only if your computer can have a floppy and a cd at the same time (some old laptops won't)
- Smart Boot Manager
- Smart Boot Manager (bis)
- smbinst.exe on Windows
If no floppy or new bios[]
- Smart Boot Manager from floppy, then install it on hard disk, then put in the Cd and reboot from hard disk, select boot from cd from SBM
