Windows 11 Will Only Work on Newer Computers

Windows 11

Episode 1808

When Microsoft's Windows 11 comes out later this year, most older computers will not be able to run it. Leo says that's because it will require secure boot circuitry on motherboards in order to run the latest OS. This is causing many to howl as they'll be forced to upgrade in order to keep up. But users have some time, as Microsoft will be killing support for Windows 10 on October 14th, 2025.

Why won't my Thinkpad work with PopOS?

Episode 1692

Myron from Bernsville, MN

Myron has an OwlCam and his LTE is still working. Leo says that he couldn't get his to work because OwlCam has closed down their service. So if it's still working now, it'll likely stop working soon. Maybe after his subscription runs out for the month.

Myron has also installed PopOS on his Thinkpad and it won't work. Leo says to turn off secure boot in the BIOS/Setup. It's designed to make sure you've installed a legitimate copy of Windows. Select F1 during boot up. Go to the security tab. Disable Secure Boot. That should fix it.

How can I boot into Linux from a USB key?


Episode 1668

Michael from Long Beach, CA

Michael wants to install Linux on a bootable USB key, but it doesn't work. It goes straight to Windows. Leo recommends Rufus for creating a bootable key for Linux. But the first thing you want to do is change the boot order in your BIOS to check the USB port first. Then, turn off secure boot. Modern PCs have this setting to protect your computer against a rogue operating system. Third, modern OS uses UEFI, not BIOS. So your computer likely needs to reflect that in your USB key. So you want to be sure your Linux Distro is UEFI compatible.

How can I dual boot in a UEFI secure boot laptop?

Episode 1045

Sterling from Nina, WI

Sterling bought a new Acer Aspire M5 laptop that has Windows 8.1 and UEFI, but he can't install Ubuntu to dual boot it. Leo says that if he goes into the settings for the UEFI firmware, he can set it up. But it's not trivial, and it's not supposed to be. The BIOS can be modified to reinfect a computer, so UEFI was designed to combat that. It also causes dual boot computers to not work in that configuration. Leo was able to do it by disabling secure boot.
