I have a centOS 7.5 server that does not boot up. Only boots up to rescue mode. This happened after a forced reboot of the server. I got the following error on CentOS 7.5 after checking the journalctl -p err
grub2 was installed after getting the correct x86_64 file into the system,
tried to mount the boot/efi, but got the error : Unknown file type "vfat" Then I tried to run dosfsck and correct if there are any dirty bits. There was a dirty bit, and it was corrected.
Tried to mount again, and the same error occurred. Unknown file type "vfat".

My fstab is as follows,
