230612 添加确定启动设置的图片Sure Start BIOS 设置图像
230611 更新帖子，尝试在 BIOS/UEFI 设置中进行其他更改
尝试在翻新的迷你电脑上安装 Ubuntu 22.04.2（桌面版）时遇到问题：HP EliteDesk 800 G3 DM i5-6500T 8 GB RAM 240 GB SSD
不要双启动，只想要 Ubuntu。
我在 USB 上创建了一个启动加载程序，可以正常启动。仔细检查后发现 USB 是 GPT 格式的。安装过程结束时，我收到一条错误消息：
Unable to install GRUB in /dev/sda
Executing `grub-install /dev/sda` failed.
This is a fatal error.
我尝试将 BIOS 中的设置更改为以下两个选项：
Legacy Support Disable and Secure Boot Disable
Legacy Support Enable and Secure Boot Disable
Removed fast boot option from BIOS.
Clearing all Secure Boot Keys -
Removed HP Firmware Runtime Intrustion Prevention and Detection (BIOS SureStart)
Removed Dynamic Runtime Scanning of Boot Block
Resetted CMOS (twice)
Reset to factory defaults and apply changes again
安装后尝试在 UEFI 和 Legacy 中从磁盘启动 - UEFI 卡在启动屏幕上并且 Legacy 找不到启动映像（假设这取决于我在 UEFI 上安装 Ubuntu）。
在终端运行启动修复磁盘时尝试 Ubuntu模式我收到以下输出：
An error occurred during the repair.
Error: NVram is locked (Ubuntu not found in efibootmgr). Please report this message to [email protected]
Please write on a paper the following URL:
https://paste.ubuntu.com/p/GPx5PKK9hy/
In case you still experience boot problem, indicate this URL to:
[email protected]
也尝试过几次重新安装 Ubuntu。
编辑 230529：除上述内容外，我现在还尝试了以下操作：
- 重置 CMOS，重新安装，修复磁盘 -> 同样的错误，无法安装 GRUB，NVram 被锁定
- 更新至最新的 HP bios 2.46，重新安装 ubuntu，磁盘修复 -> 相同错误，无法安装 GRUB，NVram 被锁定
不确定我还能尝试什么。还有其他版本的 Ubuntu 可能更好用吗？有没有办法手动安装 GRUB 来绕过 NVram 锁定问题？
