My Catalina suddenly lost boot

Today after waked up it freeze and restart. My mobo report bios corrupt and restore. And my using Catalina disk disappeared from boot list. I boot from other disk with high Sierra , Catalina boot weren't in Clover screen. After boot in HS I still can access Catalina disk.

Should I install Clover Bootloader? And it have 2 disks MacOS and MacOS-Data what disk can install?
