我使用的是安装在 250 GB SSD 驱动器上的 ubuntu 20.22。
上个月我的驱动程序空间不足，后来分区被锁定。
我尝试使用 USB 驱动程序重新安装 ubuntu（尝试不带安装选项的 ubuntu），但它无法识别锁定的分区。使用 gparted，我找不到锁定的主分区：

我得到的只是这个 busybox 屏幕：
Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline)
-Check rootdelay= (did the system wait long enough?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=xxx does not exist. Dropping to a shell!
BusyBox v1.30 (Ubuntu x) built-in shell (ash)xx
Enter 'help' for a list of built-in commands.
(initramfs)_
使用：(initramfs) cat /proc/modules
我得到附加的图像输出：
我尝试遵循其他论坛提出的一些步骤，例如：
1-Enter reboot in the prompt
2-Goto BIOS setup
3-Goto SATA Configuration
4-Change to AHCI
5-save and restart.
但我的 F12 屏幕不允许更改 SATA 配置（冻结选项）
