我发现很多问题与我的问题类似，但到目前为止，没有一个解决方案对我有用。我会尽量描述我尝试过的所有方法，所以这篇文章可能会很长。
今天我像往常一样在电脑上工作（Ubuntu 22.04），由于我暂时停止使用它，电脑进入了挂起模式。当我移动鼠标重新启动它时，它不起作用。我试着按键盘上的几个键，但也没用。出于使用 Windows 的习惯，我按了 ctrl+alt+sup。屏幕仍然空白，左上角有一个 _。我决定强制关机。此后，每次 Ubuntu 开始启动时，它都会卡在同一个空白屏幕上，上面有一个 _（它没有闪烁）。
遇到类似问题的其他人可以通过按 ctrl+alt+F1 或 F2 或其他 F 键来打开终端。但这对我来说不起作用，我无法打开任何终端。
接下来，我尝试通过 grub 菜单启动恢复模式。这次键盘出现了一个新问题，每次我按下一个键，它要么不起作用，要么执行两次命令，这使得无法导航 grub 菜单。为了解决这个问题，我进入 bios 并启用了 CSM。
启用 CSM 后，如果我启动 ubuntu，我会看到以下屏幕：
gave up waiting for root file system device. Common problems:
-Boot args (cat /proc/cmdline)
-Check rootdelay= (did the systemwait long enough?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=xxxx does not exist. Dropping to a shell!
并提示 BusyBox shell 显示 (initramfs)。运行恢复模式也会将我带到同一屏幕。
一些遇到类似问题的人通过将 BIOS 中的 SATA 操作从 RAID 更改为 AHCI 来解决这个问题，但我的已经是 AHCI 了。
我还尝试通过从闪存驱动器启动 ubuntu 来恢复硬盘中的数据，但驱动器无法被识别，我有 2 个 4TB 硬盘，而 gparted 说我只有 8GB 内存。而且整个屏幕都呈粉红色。
这一切听起来都很熟悉，就像我第一次买电脑并尝试安装 Ubuntu 时一样。我遇到了同样的问题，无法识别硬盘。显然是 VGA 连接器发生了冲突，通过在主板上关闭它解决了这个问题。我检查了一下，开关仍然关闭，所以我没有主意了。
我将非常感激任何帮助，即使不能解决问题，也能恢复硬盘中的数据。
