No CD or USB-boot on Satellite C850-Z19 - Only Win 8 boots up
Posted: 10-Nov-2012 22:04
 
Hello!

I just bought a Toshiba Satellite C850 - Z19 (Windows 8 is installed).

Although I edited the BIOS for booting with CD and USB before the HD, my usual bootable Debian Lenny and Squeeze CDs (32 or 64bit version) do not boot, only Windows 8 finally does.

I tried many BIOS config, I have no more idea; .the retailer (using Ubuntu) could not help.

Is it possible?

Some new PC's have the new UEFI secure boot. You may need to supply something called a signed key. Try searching these terms and see if a solution appears.

Quite good track.

The UEFI mode was ON in the BIOS. To remove it:

Starting the PC with F2
Advanced / System configuration / Starting mode: CSM rather than UEFI.
Typing a password for the superuser (otherwise, anybody controls your PC by BIOS access)
F10 to exit and save the parameters

And never, never forget the password.

Thanks
