>The only solution to making me happy again would seem to download Ubuntu, mount it to a USB thumb drive, and get it installed. Had I known that Windows 10 doesn’t utilize BIOS, but has replaced it with UEFI (Unified Extensible Firmware Interface), which is a secure boot option that validates programs before giving them permission to run, I wouldn’t have wasted two more days of my life trying to install my favorite operating system.

I don't understand what he's saying here. I dual boot Ubuntu on my Windows 10 PC all the time (as well as using Virtualbox).

Otherwise, I'd say his accounting of the changes shows although he may be an outsider simply by virtue of time away, he's still more savvy than the majority of the population.

He has confused Secure Boot with UEFI. Secure boot requires UEFI, but UEFI does not require secure boot.

It's both SecureBoot and UEFI.

He's probably preparing the thumbdrive the old-fashion way, jusr dd'ing the iso into it. You need a modern prep tool that's UEFI-compatible for it to boot on new hardware.

Maybe I'm missing something, but (apart from Secure Boot) I used dd to create bootable Linux USBs and booted into UEFI just fine. At least on recent Ubuntu images.

Yes, I've done Linux installations on UEFI hardware using dd'ed iso images. What are these modern prep tools, and what could they possibly be doing that dd can't do?

I think you have to disable UEFI before you can do this.

No, just the secure boot flag. Linux can EFI boot, and most UEFI bioses are perfectly happy to boot 'legacy' BIOS OS images as well. You just have to figure out how to disable windows-only mode.

If it's even enabled in the first place. I don't think my Thinkpad was, but I do remember my previous Asus did have it enabled.

There are boot managers that allow you to continue to use UEFI. I believe you do have to disable secure boot in windows though.

It requires an EFI partition of a certain type, position and size. Wiping it when you install Ubuntu can be bad.

SecureBoot.

I think it's something else. One cannot simply shut down a Windows 8+ computer any more in order to access the boot device priority. There is a menu entry for shut down, but it's mislabelled and instead it will hibernate. This is very perplexing if one is used to how it was done before. The real working procedure is orders of magnitude more complicated and documented at https://www.tenforums.com/tutorials/5831-boot-uefi-firmware-...

My experience is that there is an 'Advanced BIOS Options' dialog where I select 'Turn off your PC'. Then I can go into the BIOS and change the UEFI/SecureBoot options. One can usually enable 'Legacy Boot' for BIOS boot OSs. Certainly frustrating the first time.

as far as I remember, Ubuntu works with secureboot, doesn't it?

Ubuntu wiki seems to say so too https://wiki.ubuntu.com/UEFI/SecureBoot

If you install to the HDD and don't use any binary drivers it works fine. If you're trying to boot from USB you usually have to disable SecureBoot in the BIOS.

I usually disable SecureBoot when I install a machine. The extra protections aren't worth losing the ability to run VirtualBox.

As of some time last year VB on Ubuntu now signs its modules automatically FWIW.
