Hello, I encrypted my hard drive with LUKS and forgot my password a few days ago. As a result I have decided to wipe the hard drive and install Ubuntu instead of PureOS since I cannot regain access. I created a Bootable Ubuntu USB drive and just installed Ubuntu 22 onto my Librem 14, but when I turn it on it just shows a red screen saying “no bootable OS was found on the default boot device /dev/sda1”
If I try to boot in any way at all it just shows me the error on the screen. What do I do? How do I get Ubuntu working now on my Librem 14? It doesn’t seem like I can get it to boot at all including from a USB now. Please help.
