Question about initramfs ... default is corrupted, how to safely delete ... (Manjaro, ARCH Linux) [View all]

I'm assuming that if I delete the most recent initramfs the system will boot from the backup, and then save the backup as a new default fs .... please correct me if I'm wrong. I'm planning to back up critical files as soon as I can find my 128GB thumb drives, then start doing some seriously irreversible things to the old SSD.

I've looked for advice online, but it all seems to be mixed in with people having other kinds of problems booting, and using unfamiliar utils which I don't think I actually need ... can I get a README version ?

At worst, I'll just migrate to a new SSD, but would like to restore the old partition to working order if possible.

(I'm using Manjaro XFCE, a fork of Arch Linux, but that might or might not last.)
