全新安装 Ubuntu 22.04 后“未找到操作系统”

Question

在 Lenovo ThinkCentre 台式机上，全新安装 Ubuntu 后，出现错误“未找到操作系统”。

这是我启动计算机时看到的第一件事，之前没有打印任何内容。

我安装Ubuntu时是“擦除磁盘并安装Ubuntu”。磁盘上没有其他操作系统。

BIOS 中的引导模式设置为 UEFI。我在从 USB 启动并安装系统之前设置了此模式。

硬件：

• 联想 ThinkCentre M92p
• 只有一个硬盘 - WDC WDS240G2G0A (240GB SSD)，在安装 Ubuntu 之前在 Windows 上运行良好
• 英特尔 i5-3470T，8GB 内存

我缺少什么？

Answer 1

Thank you for all your help, this was very interesting. My machine had an old BIOS, which did NOT expose an option to disable "Compatibility support Module".

Only after updating BIOS the option showed up (as Enabled by default). When I disabled it, Ubuntu boots fine.

So if someone comes here with the similar problem - if you don't see this option in BIOS, try to update it first.
