Hey all - sorry for the vague title but that was purely out of shock and slight amusement to what has happened to me! So I own an Asus zenbook flip laptop and I have installed both windows 10 and antergos which I choose between at startup via a grub menu.
Everything was going great apart from a few minor hiccups. With being a bit familiar with Unix scripting I thought I would write myself a nice little script to rotate my wallpaper every few mins to a different one. The script simply removed the old wallpaper and downloaded a new one from a site and set it using a gettings command. I tested it manually a few times and it worked great. Time to automate it - but finding out there was no crontab in arch, I created a new service and a new timer file as per the instructions here: https://unix.stackexchange.com/questions/198444/run-script-every-30-min-with-systemd
After reloading systemd and starting my timer a few times, it didn’t seem to work so I rebooted my machine. Now I am getting a black screen requesting me to “boot and select proper boot device”… No grub menu at all… I created my service as root user by the way.
Have I completely ruined my dual boot setup?! Or is there anyway I can recover from this via the bios settings? Although annoying as I had set things up, I don’t mind installing antergos again. I am worried though about losing my windows partition because I have to bootloader for Windows (no spare cd or optical drive).
Any help is greatly appreciated!!!
