Opencore broke during Sequoia install

So I followed the instructions to build a opencore sequoia installer on an external hard disk. During install, it somehow broke. Now when the Mac boots up, it only shows two drives, an installer and Macintosh data both as normal drives.

I put another external boot as Ventura boot but it doesn’t detect in option key.

A few things I want to see now.

  1. Can I pull data off using target disk?
  2. How can I build a new external boot and show in option key?
  3. Internet recovery is available. But it doesn’t do any install as it’s High Sierra.
  4. Disk utility is available with internet recovery. Maybe I can wipe the drive and keep the data drive?

Let’s discuss.

Thanks
