[Q] Nexus 5 MultiROM lost kexec-hardboot topic

I've installed MultiROM on my Nexus 5 device and i've had it for a while and never had a problem with it. Until now. I decided to wanted to have my OmniROM in place of CM11 and I accidentally copied the secondary to primary slot in TWRP. Now whenever I try to boot up into CM11, it gives me the error code "Kexec-hardboot support required to boot this ROM. Use kernel with kexec-hardboot support." :( I have no idea what this mean and I'd really like for it to get fixed asap. If you can help, please do asap. Thanks in advance!
