RT，我划了一个新分区装manjaro，安装时关掉安装引导记录（以便用opensuse的grub2引导），结果装完后openSUSE就进不去了……

journalctl -xb 看了看，应该是某个分区加载不了。可能是安装前手贱把新分区设置成某个挂载点了吧，这该怎么办(⊙o⊙)！

感觉opensuse的多系统引导不靠谱（EFI），我试着装了几次都没成功引导，现在是也是manjaro的grub引导多系统。试着如下命令
mount /dev/sda3 /boot/efi //假设sda3是EFI分区
grub2-install /boot/efi
还是不行，我进PE，挂载EFI分区，/EFI/里面确实有opensuse文件夹，也有grubx64.efi文件，甚至连boot目录下的内核文件都有，可是还是不能引导suse，每次suse更新内核后我都要在manjaro系统下更新下grub才能使用suse更新后的内核进入系统。。

我感觉opensuse的多系统引导才是超级厉害的
我遇见过以下两种情况，一是引导被win或其他linux搞坏了，引导不起来，用opensuse的u盘，引导本地linux，选opensuse进去，用bootloader刷一下引导，就可以用opensuse来引导所有可用系统了。
二是装了多个系统（包括win和linux），觉得其他引导界面太丑了，如果引导列表没有opensuse，就用u盘，和上面一样刷下bootloader。如果列表里有opensuse直接进去，打开bootloader刷一下，重启就ok了。
经验而已，我个人用linux办公上网做科研，图形界面用的较多。
只用cli的大佬勿喷…
