Kernel Panic Attempted to kill init exitcoding=0x000000b

helloi1/4i've met this problem and it really troubled me a lot.I just install the SSH on my lab server(i hadn't realized the SSH was already installed) and it caused i coundl't access to the server. With this Kernel panic, i've already tried two previous kernels with no effect.And i also tried adding enforing=0 or selinux=0 in GRUB control pannel when i press "e" ,no effect either. I don't want to reisntall the system,since data need to be saved.Besides, i could't not boot it in recovery mode or rescue mode.Could you help me getting through this prblem? Thanks a lot,some pictures are attached.https://i.postimg.cc/NFrNY8FJ/Ujl7-BZe4-JVFm-C19.jpg
