I'm currently using Kubuntu and thinking about trying out some Arch-based distros like Endeavour and CachyOS. The issue is, these distros don't support Secure Boot out of the box like Ubuntu does. I've never disabled Secure Boot before and the instructions on setting it up in the Arch Wiki seem complicated and potentially risky, especially on some laptops like Lenovo. It feels simpler to just turn it off entirely. However, I've seen mixed opinions online—particularly in Arch forums—where some folks dismiss Secure Boot as just a strategy to keep Linux users at bay, without really discussing the actual security implications of disabling it in a dual-boot setup. Can anyone clarify what risks I would be taking by turning off Secure Boot?

At the end of the day, it really depends on what you're securing against. If you're a home user, turning it off for ease may not hurt much. But for devices that are exposed to more threats, like laptops, it might be worth keeping it on for the extra layer of security. Just weigh your risks based on your usage.
Disabling Secure Boot can make your computer more vulnerable to malware, especially those that target the boot sector. Without it, your system can run unsigned drivers and applications that would normally be blocked, potentially leading to security issues. Secure Boot acts as a line of defense, ensuring that control is handed off safely to the OS when you start your machine.
I recommend keeping Secure Boot enabled unless you have a good reason to disable it. It helps protect against some serious vulnerabilities that most users might not even think about. The idea that it's just a Microsoft thing to lock out Linux is outdated—it's about securing your entire system.
That's a good point! But I do wish it wasn't such a hassle for smaller distros to get support from UEFI vendors.
Secure Boot does help protect against certain malware, particularly those that can infect your firmware and kernel. While it's less of a concern for typical users, it can serve as a safeguard against advanced attacks. If your machine gets compromised, it might be challenging to fix without Secure Boot in place, especially if the malware embeds deeply.
Honestly, if you're careful online, you'll be fine. Secure Boot isn't a magical shield. The bigger risks come from your general browsing habits—like clicking dubious links or downloading unverified software. Just be smart about where you get your files from, and you shouldn't have too much to worry about with Secure Boot off.
Definitely! Just stay away from sketchy sites. It's about judgement more than technology sometimes.
True, but the real risk depends on your usage. If you're cautious and avoid shady software, you're less likely to run into problems. Sometimes, Secure Boot can be more of a nuisance than a necessity for the average user.
