Thanks for the links, they appear to be useful, but now I’m at another obstacle. I’m following what both articles say and have edited /etc/default/grub to fit my needs, resolution-wise. But afterwards, when I run “sudo update-grub”, I get an error saying “/usr/bin/grub-probe: error: failed to get canonical path of ‘overlay’
. I’ve managed to workaround that error by getting “realpath ‘overlay’” and making the missing directory. Now when I run “sudo update-grub” I get an error line “/usr/bin/grub-mkconfig: line 248: /boot/grub/grub.cfg.new: No such file or directory.”
This is when I noticed that the iso doesn’t even have a /boot/grub directory (which I’m not sure is normal or not). So, I did a similar workaround and made the /boot/grub.cfg.new file. Now when I run update-grub, this is what I get:
Generating grub configuration file...

done.
I’ve searched online, but of the ones that are relevant to my situation, it was suggested that there may had been a mistake when preparing my live usb.
The command I used to prepare my usb was this (based on ArchLinux wiki guide for doing so on macos.
dd if=<directory of iso file> of=/dev/rdisk3 bs=1m
Any tips would be appreciated. Thanks
