Happy to hear you're making progress, though I won't be able to help you as much at this stage because your system is setup up differently from mine.

Since you've reached the initrmfs terminal, you just need to locate "vmlinuz" now that the drives have been reordered. That should be wherever the root of filesystem has been mounted (e.g. "/"). Thankfully initrmfs will have all the basic functions of a standard terminal. So try "lsblk" to list all the drives/partitions and their ids, and look for the partition that has the "/" MOUNTPOINT. That should be the name you use for the root in the second grub command.

Failing that, you could use other basic terminal commands like "ls /dev", 'find / -name "vmlinuz"', etc. to figure out your particular setup.
