You are having problems inside the VMware BIOS because you’re unable to navigate the BIOS menu due to messed up key mappings. For example, the arrow keys among other keys don’t work.
If you’re running VMware server on Ubuntu, you will want to stop the key mapping madness in X:
echo ‘xkeymap.nokeycodeMap = true’ > ~/.vmware/config
or put this line into /etc/vmware/config for the change to affect all users.
