"filename 'var/db/payloads/boot/useropts' not found" Please refer to the log file for more details.
The error indicates that the file named 'var/db/payloads/boot/useropts' is missing. This is likely because the basemisc.tgz file located in the /bootbank/ directory is corrupted.
Replace the corrupted basemisc.tgz file with a working version from the same ESXi version. This can be done by obtaining a good copy of the file from another identical ESXi installation or by downloading it from Broadcom's official support site.
