    windows on hd1, deepin then planned to install on hd2. while installing, there was a efi warning, and i didnt go thru it, then clicked "yes". After installation, the grub has no windows option, and I tried many methods, including sudo update-grub, etc , which dont work at all. However, if i need to go windows, i need to bios to set boot from hd1, then fine to go to windows. Is that deepin installation deleted my windows efi coz efi warning that time? I saw the windows harddisk management, hd1 seems no windows efi, so how to restore the windows efi deleted by deepin?

    Try to this step：

    1.Use command to install deepin repair tool：

    sudo apt-get install deepin-repair-tools

    2.Open the repair tool

    3.Select the "Boot Repair" menu and click the "Repair"：

    4.If deepin repair tool does not work ,you can start to PE and use  NTBOOTautofix to fix it.
