Boot Issues smbios and system identifier

Anyone that can help with this issue?

Could you walk me thru the step by step how to do the command line script, specifically what to type and when to type it

To delete smbios.plist:

Boot with -s

at the command prompt type in (<enter> = the enter key)

fsck -fy <enter>
mount -w / <enter>
sudo rm -rf /Extra/smbios.plist <enter>
reboot <enter>

I believe I successfully removed that file, but I am not for certain.

When booting with "-v -x -f" the text never told me anything about a problem with the computer as it had previously done, and in fact never actually booted... (I attached the screenshot of where it hangs)

I rebooted how I normally would, but still through my USB and I get to the grey Apple logo screen and the wheel gets stuck. The computer appears to think for a very long time ~8minutes, but does nothing.

I also tried to launch into the Unibest USB install and it hangs there too.
