My laptop, an older Toshiba A100-250, won't boot from a CD or DVD when the HD is attached.
I tried everything I can think of:
- Update the BIOS
- Reset BIOS to default values
- Change boot order in BIOS
- Press F12 during startup to select the 'CD/DVD' as the boot device
Despite all efforts, it still won't boot from a bootable CD or DVD.
If I detach the HD (sata) all is working fine. So the CD/DVD reader is ok and the media is bootable.
As a last resort, I tried disconnecting the HD during startup and reconnect it when the laptop is booting from the CD (bad practice, I know). This resulted in Windows seeing the HD but refuses to install to it because it was not detected in BIOS.
What else can I try?
