If you want to boot from CD-ROM/removable disk temporarily. you need only press the hot key for boot sequence and select the boot media. this hot key is F12 for most systems, but not for everyone.

But not all the essential changes can be resolved easily without access. however, We know there are so many softwares that can change these settings in BIOS, some information can not modified in real BIOS circumstance.

When you met a BIOS boot problem(Note: BIOS boot problem is not always the operating system boot problem). I think you should try it through common ways. not for professional software.
