我有双启动 Windows/Ubuntu。尝试安装新的 M.2 驱动器后，我一定是碰到了 CMOS 或其他东西，我的 BIOS 中的 RAID 配置被重置了。所以我再次启用了 RAID，但我的 Ubuntu 启动选项消失了。经过一番谷歌搜索后，我尝试通过 Boot USB 重新安装 GRUB。我按照这个邮政
重新启动后，我得到一个 grub 启动菜单，我选择 Ubuntu，然后出现错误：“initramfs 解压失败，解码失败”。
谷歌搜索告诉我我需要切换COMPRESS=lz4到COMPRESS=gzipetc/initramfs-tools/initramfs.conf。所以我通过加载 Boot USB、将我的 / 挂载到 /mnt 然后 chroot 进入它并编辑 intramfs.conf 来做到这一点。编辑后，我尝试运行update-initramfs -u并出现错误：
W: Couldn't identify type of root file system for fsck hook
我的/etc/fstab：
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

因此，即使我更改 initramfs.conf 后重新启动并尝试启动，它仍然会失败并出现相同的错误。有人知道这个吗？我惊呆了。我不知道是某些 Windows 更新搞乱了一切，还是我忘记了 Linux 更新，但这真的很烦人。我可以正常启动 Windows。
