    Legacy mode is not supported


    HI,

    Ive bought a brand new Laptop with no operating system (DOS)

    While trying to install windows 10 from a bootable USB stick the following problem occures :

    I cant activate Legacy mode ,the option is not even there ! ,Only UEFI is supported .

    Note that i've disabled fast boot and secure boot.

    I can only access EFI Shell ,which i dont no nothing about .

    I can only say that shell's ( Device mapping table) shows fs0, blk0,blk1,blk2,blk4 and all are set so <null> which i think all the peripherals including the Harddrive are disabled.

    Please help me solving this !

    :)

  2. Support Had Me Change From UEFI to Legacy mode in BIOS Re: DISASTER


    This was Acronis True Image 2018 support not MS or Lenovo (P51). Those familiar with True Image know that you can create bootable media on a flash drive to run the software. No problem with True Image 2017 but True Image 2018 did not work. Although the flash drive loaded the program the GUI was garbled and I was unable to navigate. Support had me switch from UEFI back to Legacy and that was a bad idea. Sorry for the caps but this was what I wrote back to Acronis support. FYI the rest of the message was not in caps:

    SUPPORT: I have discussed this issue with the Experts team and they have suggested testing whether changing from UEFI to Legacy mode in BIOS fixes the issue or not. This step is suggested for testing purpose only.
    THAT WAS A TERRIBLE SUGGESTION. I WENT INTO THE BIOS AND DID AS YOU INSTRUCTED AND CHANGED FROM UEFI TO LEGACY. I CLICKED EXIT AND SAVE AND WITH THE FLASH DRIVE PLUGGED IN THE 2018 BOOTABLE MEDIA I WENT TO BOOT MENU OPTIONS AND CHOOSE BOOT FROM FLASH DRIVE AND I WAS DROPPED BACK INTO THE BOOT MENU OPTION. SEE ENCLOSED PICTURE. I THEN SELECTED BOOT FROM THE SSD DRIVE AND I WAS AGAIN STUCK IN A LOOP THAT DROPPED ME BACK INTO THE BOOT MENU OPTION. I THEN TRIED BOOTING FROM THE SECOND INTERNAL HDD OPTION AND AGAIN WAS DROPPED BACK INTO THE BOOT MENU. I COULD NOT GET BACK INTO THE BIOS TO CHANGE BACK TO UEFI FROM LEGACY. I HAD TO DO A HARD SHUTDOWN AND POWER BACK ON AND ONLY THEN WAS I ABLE TO GET INTO THE BIOS AND CHANGE BACK FROM LEGACY TO UEFI.

    This is a pic of the loop I was caught up in. Why do you all think I was not able to boot either from the flash drive or the SSD or the HDD once I changed from UEFI to Legacy in the BIOS? TIA.

    That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

    At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

    Difficulty setting BIOS to boot in Legacy mode

    I tried all that is suggested by HP but it makes no difference, the Legacy mode simply refuses to stay put. I always ensure that the settings are confirmed before exiting the Setup but that's just it ... the machine always goes back to Secure Mode. Annoyingly,
    prior to the iOmega software being installed and the consequential failure to boot, I could set the PC to boot into Legacy mode with no problem if I chose to.
