My Aconia Iconia W3 will not boot from an USB DVD. Secure Boot is unset, USB DVD is a t the top of the boot list, and the DVD drive is connected via a Belkin extenally powered USB hub. The DVD spins up at the start of the boot process, but the table then goes through a normal boot. Suggestions?

    Did you erase the certificate library under Security in the BIOS ? Secure Boot must be ON to erase the library and then you can turn secure boot off. The you should be able to boot anything bootable.

     

    I leave everything (UEFI) on and have no problem booting from either DVD or a USB BluRay drive as long as the boot drive is configured properly and signed by Microsoft.

     

    AFAIK Win 8 & 8.1 are the only OSs that have the thremal management drivers for a ventless design. With anything else you have to be very careful to avoid overheating. Good aairflow over the case is a must.

    I have looked in the Security section & could not find anything identified as a certificate library.  I tried "Erase all Secure Boot Setting" and disabled "FTPM Support", but to no avail. the DVD is being read, but then the boot reverts to the internal disk.

    Once you "Erase all Secure Boot Settings" you need to go to "Boot" and disable Secure Boot. FITM does not apply.

     

    The key here is you need to be able to run MSINFO32 from desktop and have the BIOS MODE  read "Legacy" rather than "UEFI".

     

    Just be aware that anything other than Windows 8 is liable to need agressive cooling.

    I have  "Erased all Secure Boot Settings" and disabled Secure Boot., but still have the BIOS mode set to UEFI in System Information. What next?

    i have heard that only a few linux os will clear uefi certificates. my guess is that if you make a usb right and place the right version of os install iso on it, it should see it. i never tried it though.

    Be aware that very few, if any, of the Linux distributions are supporting the driver for temperature control. These fanless systems can burn themselves out without that functionality.

    I would say that the reason the USB cannot boot is basicaly the same as for my Iconia 8 W, the UEFI is IA32(32bit) and most linux distributions only support 64bit. There is a nasty hack I developed that allows me to boot 32bit version of Arch Linux installer on the hardware, but I wonder if it is worth the troubleSmiley Happy.

    Well the switch 12 supports Legacy mode but then it won't boot from its own SSD. I suspect it requires the power management to enable the "turbo boost" so will always be throttled back to 800 MHz if not present.

     

    Switch 12 seems completely different from the rest of the Switch lineup.
