    I have an SSD and want to install Win 11 from a USB stick on it.
    But the installation is stopped, because the disk has an MBR partitioning, and to install it needs to be GPT.


    I have searched the internet and copuld not find nything that works...

    When you boot from your USB key & get to the 1st prompt, open a cmd windows by pressing SHIFT+F10.
    run diskpart, then:
    Code:
    lis dis
sel dis 0
cle
con gpt
exit
exit
    "lis dis" lists all your drives. If your SSD is not disk 0, change the command "sel dis X" to your disk...
     
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    Thank you I will try that. I tried diskpart a few times, but it never worked. Maybe, as you write, because it is always disk 1....

    There is only one Volume on the stick MBR, and diskpart can only convert a whole disk...


    Added in the evening:
    I tried another SSD, an old Crucial, and the clean worked at the first attempt and the installation was soon finished, so:

    THANK YOU !!! :D
