    Hello guys i have  Lenovo Ideapad 520 and i install the windows on UEFI correctly  on my SSD ( i can see Windows Boot Manager UEFI on BIOS)
    i download the lastest version of os  from deepin website( 15.6 )

    i create bootable USB   with Rufus and  Partition Scheme selected on MBR Scheme for UEFI
    and i create a unallocated partition for installing deepin os alongside windows
    on installtion  i cant  see any option like UEFI or Select bootloader Which were in previous versions ( like below picture  and the picture is not mine )


    and when i going to advanced mode and create partitions ( /root , / , swap )
    i cant select bootloader for UEFI  and after the finishing installtion  UEFI doesnt install and i cant see it on BIOS
    when i restart the system , it normaly goes to windows without asking deepin or windows
    can anyone help me why i dont have this option ( Change Boot loader on bottom left of picture ) ?

    Hi bro,I didn't have the problem simlier with yours.But i can tell you how i install my double os(deepin+windows10),First,there is only windows on my computer,and in the bios,I set it only
    use UEFI mode.And I creat a bootable USB installer with DEEPIN_B tool,it is just in the iso,you can unzip the iso and you will see it.
    when I install the system ,I enter the USB installer by UEFI ,and I choose the simple mode ,then choose a empty partition ,then next ...config something then reboot .
    Done.
    I just tell you how i used to install it. I just download a new image and i will install it by advenced mode .
    you can contact me with telegram @skylargao

    Try creating a bootable USB using deepin's own USB maker, it's located in the .iso . If you still can't see the USB in the boot loader, try enabling booting in insecure mode, works most of the time. You can re enable it after it's installed.

    Try basic installer this time, and again, turn off secure boot from bios before proceeding with anything.
    If issue still persists, you can always install a previous version of deepin then update to 15.6, according to the website, 15.4 and above can be updated to 15.6.

    thats the error when i grub-install

    1. Installing for i386-pc platform.
    2. grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
    3. grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
    4. grub-install: error: will not proceed with blocklists.

    HI

    Uefi must work with GPT disk
    Legacy install can work with MBR

    i fixed that issue and i want to share my solution for other person

    first of all i boot from Live Deepin and going to gparted  , and i delete all of my partitions ( dont worry  i dont have important files )
    after that i create bootable usb with rufus for windows image and at this time i used the GPT Scheme for UEFI
    i run the windows installtion and change the disk from mbr to gpt
    after the windows installtion complete i create a bootable usb with deepin boot maker
    i setup deepin with easy install and i dont going on Advanced mode to create partitions
    when the pc reboot after installtion  i saw the grub menu and i could choose between windows or deepin



    just another qouestion :
    i setup deepin with easy install and i dont create partitions for /root , /home and /swap , can i create now ?

    You don't have to it creates them on its own, I did use the Basic Install approach and it did everything by itself. You can check by opening the system monitor and see the amount of swap you have.
