So I tried installing Xanmod kernel through the official instructions listed on the website. Everything went fine, up until I noticed that for some reason,
wasn't executing the second part of the command, so I tried just executingsudo apt update && sudo apt install linux-xanmod-x64v3
on its own, and it seemed to have worked properly. After that, I restarted my computer, and now we're here.sudo apt install linux-xanmod-x64v3
The computer starts, and gets to "GNU GRUB." First thing I notice is that now all of my devices fail to start (Keyboards, mice, etc), so I can't interact with menus at all. After 30 seconds, it automatically attempts to boot into Linux Mint, which brings up a screen that eventually reads this:
Then, finally it boots me back to GRUB, which I obviously can't do anything with. An important thing I think I should note is that I enabled "ultrafast boot" via my UEFI before this, which even said that it boots so fast that I won't be able to access the UEFI without the OS. I am about 90% aure that this is why I can't access my BIOS and why none of my deices are loading. Yes. I know how stupid I look right now, but that's what I did. Disconnecting and reconnecting my devices does nothing, so I'm stuck with a computer I can't fix through 'normal' means.error: bad shim signature
error: need to load kernel first
Press any key to continue...
Failed to boot both default and fallback entries
Press any key to continue...
That's just about all the context I can think to add. For the record: I am well aware that these forums probably aren't the best to get help on this, and that this may not be the best category for it, but due to my distaste for Reddit and, as far as I can tell, a lack of any resources on this sort of thing from Xanmod themselves, these forums are probably my best bet. And I'd rather get chastised for posting to the wrong place than attempt to fix this problem myself and end up making it worse. I just want to get this resolved as soon as possible. Any help on this would be appreciated.
UPDATE: I tried using the keyboard that came with my computer, and somehow that worked. It must be that Ultrafast Boot is set to load that keyboard's device driver, but not any other devices that didn't come with the computer. Using that keyboard, I was able to go to my computer's UEFI and disable ultrafast boot, and even get Xanmod working by disabling secure boot, but it had issues using my Nvidia graphics card, even with the proper drivers installed, and I wasn't in the mood to spend even more time debugging things, so I just ended up reverting back to the newest 'stock' kernels. Tl;dr: Ultrafast boot is terrible, don't use it.
