UCS-FI 6454 secure boot

[00u1ab28axbOOzhqE5d7]

I'm trying to factory reset UCS-FI 6454 using init system in switch boot but the loader look like it is some sort of security boot and the loader says "Trying to read config file /boot/grub/menu and I can't type anything and it boots on its own and i cannot access the switch(boot). Is there any work around to access the switch(boot) to copy the bin file over to tftp, initialize everything and copy the file back?

Disregard. I noticed the firmware can be downloaded without a service contract so there should be no issues. Normally an agreement is needed. Just remove the drive and erase it and then follow this. https://www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-6400-series-fabric-interconnects/220718-troubleshoot-and-recover-6400-series-fab.html
