i'm trying to install windows 11 on a new disk but i get two errors, that are a sort of paradox:

  1. motherboard asus x570 hero VIII wi-fi. the secure boot issue: set on UEFI secure boot in bios, but no way, is seen as legacy with no secure boot activated. all other parameters for win 11 are ok.
  2. if i try to modify from MBR to GPT the disk into wich i want to install win 11, also via partdisk, i receive an odd error message: specified dik is not convertible, ...is it seen as DVD?!? but it is a NVMe wd Black formatted in NTFS. empty

    If those steps did not resolve this, then it would be best to contact the support for your system on their website, or disable the requirements for Windows 11, you can enable them later.

    yep i tried the keys wiping and restoring. and i put the last bios. no way. actually a new field "uefy only" under secure boot options appeared, but nothings changes also with that. bios 4805. i was hoping maybe someone had a similar issue with this board, i can't find any help on the web. if i can't fix this i guess i reinstall windows 10. or i disable the requested win 11 required features, even if i'ld prefer not...

    If Windows does not see Secure Boot active, try resetting TMP keys in your BIOS to factory keys to see if that works, if not, check the support page for your PC or motherboard to see if there is any BIOS update available that may need to be installed.

    1. the dual boot comes later. windows is able to set it while you install the second Os: but i can't install w11 on the new disk. because it fails: secure boot is not active, even if i turned it on, UEFI ONLY, in the bios of the asus x570 crosshair viii
    2. what you suggest is not possible, because installation of w11 is aborted for reason at point 1. unless you say i could make it installing win 10? then aborting installation (at least it change from MBR to CPT?)

    btw what you suggest i already tried from command prompt, launched as Administrator from win 10, but it gives the error: specified disk is not convertible....

    first problem here is : why win 11 sees no secure boot active while it's turned on in the bios? and UEFI only? why?

    Hi, I am Dave, I will help you with this.

    1

    You seem to have Windows installed on that PC, is that on another drive, are you going to dual boot that PC?

    2

    To convert that drive from MBR to GPT on that drive, use these steps, this process should work.

    At the very start of the Installation Process, press Shift + F10, or Shift + Fn + F10 to open Command Prompt

    Run this command and hit Enter:

    diskpart

    Run this command and hit Enter:

    list disk

    (Make note of the disk number you want to convert and enter it into the next command - replace X)

    Run this command and hit Enter:

    select disk X

    Run this command and hit Enter:

    clean

    Run this command and hit Enter:

    convert gpt

    Then close Command Prompt
