extlinux.conf file error, can it be edited in bootloader?

[Abandoned Brain]

Try maybe,,, /usr/bin/nano

Thanks, and normally I'd lean on nano as my editor of choice. However, I'm still down in the bootloader, so there's only a limited number of applications I can run. Heck, ls doesn't even work like it does in the OS!

That said, I was able to load Manjaro on an SD card and I was able to boot into it. I was able to mount the eMMC's /boot and edit the conf file. Unfortunately it did not fix the issue, even after I overwrote the original /boot with the SD card's /boot (and grabbed the correct PARTUUID). I can get it to show the splash logo, but it never goes past that point (never gets to login), and if I change the console I get a prompt but the keyboard doesn't work at all.

At this point, I'm just going to grab a few files from my original home dir, and do a full reinstall on the eMMC. Probably good practice; maybe I'll try Gentoo this time! 

Thanks all! I've been running Linux on and off since the Caldera days, and I learn something new every day.
