    Wait for the EFI shell to leave you at the terminal.

    Type:

    edit startup.nsh
    

    Type the path to your desired .efi file. Typically:

    fs0:\EFI\ubuntu\grubx64.efi
    

    Ctrl+S to save.

    Enter to confirm.

    Ctrl+Q to exit back to shell.

    Reboot the VM. It will still display the EFI shell but will load Grub automatically.

    1.Problem

    Problem with VirtualBox 5.x running on GNU/Linux Debian 9.x host:

    EFI-enabled guest suddenly boots only into UEFI Interactive Shell.

    输入图片说明

    It waits for 5 seconds and then it drops to Shell>.

    I don't remember any modifications, which I would have done, neither to the host, nor guest, or VirtualBox itself.

    2.Plausible fix:

      In UEFI Interactive Shell, enter the file system:

    fs0:
    

      Following up with creating this file:

    echo '\EFI\ubuntu\grubx64.efi' > startup.nsh
    

      Press CTRL+S to save the file.

      Press ENTER to confirm the file name.

      Press CTRL+Q to exit the editor.

      Restart the Guest:

    reset
    

    Important notes

      For some reason you have only a few seconds to edit and save the file. If it takes you longer, then the guest may react with a significant delay. Or it may even freeze.

      Replace debian with your system's id, e.g. ubuntu. You may verify this by simply going into the \EFI\ directory and running ls.

    Another way

      If you don't succeed, and supposing your guest is Linux type, I myself had to do it:

      Boot from live USB with any Linux.

      Mount the root file system.

      Create this file on the mounted file system, adjust the path to wherever you have mounted it:

    /boot/efi/startup.nsh
    

      Enter the above explained line to it.

     While the PC is in UEFI mode, the Windows PE version must match the PC ... A PC in 64-bit UEFI firmware mode can only boot 64-bit versions of Windows PE. A PC in 32-bit UEFI firmware mod
    

    64位的UEFI FW只能 支持64位的 WinPE

    32位的UEFI FW只能支持32位的 WinPE

    如果要兼容以上两种模式就需要FW同时支持UEFI和BIOS模式,打开BIOS 模式后两者都可以,打开UEFI模式只能启动64位的winpe3.0(打开CSM)和Winp4.0


    While the PC is in UEFI mode, the Windows PE version must match the PC architecture. A PC in 64-bit UEFI firmware mode can only boot 64-bit versions of Windows PE. A PC in 32-bit UEFI firmware mode can only boot 32-bit versions of Windows PE. On PCs that support both UEFI mode and legacy BIOS mode, you may be able to run 32-bit Windows PE on a 64-bit PC by changing BIOS menu settings from “UEFI mode” to “BIOS mode”, assuming the manufacturer supports legacy BIOS mode.

    1. 买了游戏本首先是装双系统了,这样可以将其当做我的Linux服务器使用。
      而装双系统就是一件坑贼多的事情,尤其是用Rufus里面采用UEFI模式装双系统时(因为我的电脑就是GPT分区,Windows系统是以UEFI模式启动的,为了两个系统启动方式可以一致),贼坑,它不支持support legacy模式,但是又无法从only UEFI模式启动,可能是我技术不够硬。直接搬救兵:简书之-----超详细!Win10(UEFI启动模式)安装Ubuntu18.04双系统,按照这里面的用ulstraISO软件装启动盘,可以实现BIOS以UEFI模式从U盘启动。。。
    2. 你以为这就完了?独立显卡还会给你找麻烦,如果不进行设置,U盘启动界面就是一团乱码(黑屏+几行英文+彩色斑点),还以为电脑被搞GG了。还是搬救兵:双系统Ubuntu 18.04安装时卡死
      从而我们以通过nouveau的方式进行集成显卡的驱动,这样就可以进去U盘启动界面进行Ubuntu系统的安装了。
    3. 你以为这样就完了?二中链接的最后一步多数情况下是不可靠的,也是不推荐的。那怎么才能重新启用NVIDIA独立显卡的驱动呢?继续搬救兵:Ubuntu 18.04 安装 NVIDIA 显卡驱动
      这里提供了三种安装显卡驱动的方式,我采用了第三种。但是安装过程显然不是很顺畅,中间会让你安装兼容的32位blabla,缺少一个或多个文件,覆写(override)…,方正能安装就给他安装了,覆写就覆写吧,总之是一路安装下去,最后就基本成功了。通过nvidia-smi如果能看到表格中的各项参数,就说明安装成功了。
