Try these combinations at startup to enter Bios:

- F1 or Del.

- Some require pressing reset twice

- Ctrl + Alt + Enter

Hope these may help.

Is this a Toshiba Satellite Pro CDT420 Laptop like this?

If so, then Toshiba refer to it as Satellite Pro 420 CDT and you press the [ESC] key until after the POST finishes, and you should be prompted to press F1 to enter the CMOS setup, according to this page:

and this one:

According to the following page, you should also be able to use the hotkey "C" to force a boot to CD:

"1. Boot From the Boot Device Menu (temporary setting):

When the TOSHIBA splash screen is displayed when you first turn on your computer, a boot menu prompt may be displayed for a few seconds near the bottom of the screen, indicating that a key (F2 or F12, for example) can be pressed to display a menu of boot options. The time allowed for detecting the keypress is very brief, so you'll need to be both prepared and quick.

On some models this prompt reads Press F12 for boot menu. On others, it may say Press C to boot from CD-ROM. On still others, there may be a row of colored icons representing the various boot devices (HDD, FDD, CD, LAN, PCMCIA, etc.) Press F12 while these icons are displayed, and then use the arrow keys to move the cursor from one to another. As new models are released, the wording of these prompts may change.

The selection of a boot device from any of these boot device menus affects only the current startup operation; the next time the computer is started it will follow the boot priority setting established in BIOS Setup.

2. From the Boot Device Hotkeys (temporary setting)

Immediately after pressing the power-on button, press the hotkey for the device from which you wish to boot:

Hotkey Boots from device
N - Internal LAN adapter4

The computer will boot from the selected device if it finds a bootable operating system, otherwise it will search for a bootable device, following the boot priority set in BIOS Setup.

- "IDE CD-ROM" refers to the computer's internal CD-ROM drive (built-in, SelectBay, or built-in to a Toshiba docking device).
- "ISA FDD" refers to an internal or SelectBay diskette drive, or an external diskette drive that connects to the PC through a special Toshiba-proprietary connector.

Not all models support booting from a USB-connected diskette drive.
Not all models support the hotkey for the internal LAN adapter, even though they may support booting from LAN.
The selection of a boot device from Boot Device Hotkeys affects only the current startup operation; the next time the computer is started it will follow the boot priority setting established in BIOS Setup".
