Me: Finally got Arch.

Also me an hour later: Fuck why doesn't it boot now

If you have a Core Duo/Core 2 Duo machine, then there's a bug in Linux kernel (yes, Linux has bugs. In fact, every software written by a human would have bugs. It's inevitable). Try to boot using Arch Linux Live CD which isn't running Linux 4.18, chroot into your system and add "tsc=unstable" or "clocksource=hpet" in kernel parameters

My arch didn't boot because there was no byte left to store anything.

Back to manjaro

... but think about how much you learn by being unable to boot!

My best time was installing Arch, then a week later upgrading it and my Xorg config no longer worked so I no longer had a desktop environment... hilarious fun.
