    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
