在 Arch Wiki 找到了这样一段话

Alternatively, the kernel can be configured to load the vmd kernel module before looking for the boot disk. Add vmd to the MODULES array in your mkinitcpio.conf and regenerate the initramfs

Dell XPS 13 (9310)

Dell XPS late 2020 edition. In some units, the NVMe drive is configured to operate in RAID mode by default. This may cause the bootloader to not find your boot disk. In order to fix this, press F2 to enter the Dell UEFI. Go to Storage, NVMe Operation, and make sure that "Select AHCI/NVMe" mode is selected.

于是将 VMD 加入了内核预加载模块当中, 准备启动时发现无法进入 GRUB

貌似是因为 GRUB 不支持 RAID ON

systemd-boot

systemd-boot, previously called gummiboot (German for: "rubber dinghy"), is a simple UEFI boot manager which executes configured EFI images. The default entry is selected by a configured pattern (glob) or an on-screen menu to be navigated via arrow keys. It is included with , which is installed on an Arch system by default.

切换 sytemd-boot 之后正常启动了

又发现 lts 的内核无法读取 / 分区

….好吧暂也不知道是哪个版本开始支持的

继续用 Linux Zen 内核吧

Windows

为了避免重装, 咱在切换之前得打开 CMD 输入


bcdedit /set {current} safeboot minimal

在下次重启进入 安全模式

此时再进入 bios 切换模式

成功启动后, 再关闭安全模式


bcdedit /deletevalue {current} safeboot

最后

至于 AHCI 和 RAID 在这台机器上的具体使用区别

以及 Linux 内核啥时候支持这个模式的

等有空再研究了

~~至于为什么切换回来, 还是怪我这该死的强迫症~~
