Re: [GTALUG] UEFI bios/firmware
Hello LenThank you for your help.In at least 3 computers I have come across, that has this option grayed out. As shown in pic1 of that link you supplied. So it is not accessible. Every link I came across, basicly had the same solution you described. There for those three computers can not have a true format done. All three have corrupted hinden partions. Putting a new hard drive will not help either. New mother boards would help.Cheers Abby Sent from my Samsung device -------- Original message -------- From: Lennart Sorensen <lsorense@csclub.uwaterloo.ca> Date: 08-11-2015 10:25 (GMT-05:00) To: GTALUG Talk <talk@gtalug.org> Subject: Re: [GTALUG] UEFI bios/firmware On Tue, Aug 11, 2015 at 12:39:02AM +0200, Abby Bassie-Cripps wrote:

<div>So Len, are you able to tell me what the steps should be to disable the secure boot in windows 8 & 8.1? Other than the simple out dated method that we all know about?</div>
Well from what I can find the process is: When you see Toshiba logo, hit F2, then you should be in the UEFI (BIOS) settings. Under security tab there should be an option for 'secure boot' which you want to set to disabled. If you want to keep windows working, that should be all you change, and then you should be able to install linux as long as the distribution is new enough to support UEFI booting. If you don't want to keep windows and you want to use an older style distribution that does not do UEFI booting, then you have to also find the "CSM boot" setting (under advanced/system settings) and turn that on. That will break booting windows 8.1 on the machine though. I would personally stick with UEFI booting these days. https://aps2.toshiba-tro.de/kb0/TSB2B03F30002R01.htm -- Len Sorensen --- Talk Mailing List talk@gtalug.org http://gtalug.org/mailman/listinfo/talk
I had this same problem on an Acer laptop until I discovered you need to enter a password and enable the password. When you are finished disabling things, you can then disable the password. Peter

So you have to set a supervisor/admin password for the bios before you can change the secureboot setting? Crazy. :) -- Len Sorensen

I mentioned the other day to someone on this list that you may have to set a supervisor password in the BIOS before you can change the UEFI and/or secureboot setting. Give that a try and see if it helps. Just remember to removed the supervisor password if you don't really want it long term. -- Cheers!

Well you might have to type an admin password to unlock some settings. But windows 8 logo certification requires that the end user be able to change that setting, so there has to be a way. Otherwise it would not be allowed to ship with a windows 8 logo sticker on it. Some places say that if a supervisor password is set it has to be cleared before you can change secure boot. And you have to be sure windows 8 is really shutdown before entering the bios, which supposedly you do by holding shift down when telling windows to shutdown/restart. -- Len Sorensen
