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?
