<div dir="ltr"><div><div>FWIW, I'm dual-booting Fedora 20 and Windows 7, both in UEFI, using refind [1] as a boot manager, though you could also use grub. It works pretty well, as I can swap my Windows disk in and out of my laptop, and it either does or doesn't show in the boot list. I have refind launch Linux directly, rather than chaining through to grub. My laptop doesn't support secure boot, and I haven't tried refind in that situation. Apparently refind has the ability to support dual-booting both UEFI and legacy systems, so it might be a nice middle-ground if you don't want to go completely UEFI yet.<br>
</div><br>However, I was recently working on my Dad's Windows 8 laptop, and took the opportunity to fiddle around with it. What I learned:<br><br>* Fedora 20 has the necessary signatures to boot with secure boot on from USB (dd the live iso to usb from my laptop)<br>
</div><div>* Windows 8 will boot with secure boot turned off<br></div><div>* Windows 8 can't switch from UEFI to legacy bios (Neither can Linux without manual effort, though)<br></div><div>* Windows 8's backup program is called Windows 7 File Recovery. Not applicable here, but funny anyway. Their developers might try porting `sed` before Windows 9...<br>
</div><br>It might be that disabling secure boot in your bios is also disabling UEFI, which makes it seem like Windows needs the former, when it really only needs the latter.<br><div><div><br>1. <a href="http://www.rodsbooks.com/refind/">http://www.rodsbooks.com/refind/</a><br>

Mind you, not all distros support UEFI/Secure boot yet. Ubuntu was one of the earlier adopters, but I can't speak for all the distros. You'll have to investigate.</div>

Am I understanding what you said correctly?<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Sat, Apr 5, 2014 at 8:05 PM, CrankyOldBugger <span dir="ltr"><<a href="mailto:crankyoldbugger@gmail.com" target="_blank">crankyoldbugger@gmail.com</a>></span> wrote:<br>

I found that if you install Ubuntu (by itself or in a dual boot) on a UEFI machine, then the state of the UEFI/Secure boot at the time of install must be the same when you're running Ubuntu. In other words, Ubuntu will work regardless of UEFI/Secure boot, but when you install Ubuntu it looks at whether or not UEFI is on or off and installs the necessary pieces accordingly. So if you do the install with UEFI off, you can't turn it on later, or vice versa.</div>
