UEFI Frustration
I am sure you are all aware of the secure UEFI limitations, but I wanted to vent a bit.
I was playing with my new laptop and I thought it would be fun to experiment with a UEFI installation. Code:
mnt archlinux-2012.12.01-dual.iso /media/iso Quote:
Code:
dd if=archlinux-2012.12.01-dual.iso of=/dev/sdf bs=512k Oh well, I paid the Windows tax. At least they still allow for legacy boot options. The legacy bios seems to boot faster than UEFI, I just thought it would be nice to experiment with my laptops new firmware. |

Linux Foundation to offer signed solution for UEFI Secure Boot conundrum I guess I'll wait to this trickles down to the major distros... Or use Fedora... Quote:
Hopefully, PCs continue to get legacy bios options in the mean time. |
And again it goes. You are not restricted by the UEFI firmware, but by the Secure Boot function. This is why it works in leagcy BIOS mode (which doesn't support Secure Boot). Just disable Secure Boot in the firmware setup. If you have a laptop with Windows 8 logo somewhere on it there must be such an option, if there isn't such a logo it depends on your lack if that option exists.

I tip my hat to you TobiSGD; your good at what you do! Have a good week! |
Unfortunately, Acer does not allow the secure boot to be disabled. The option is greyed out and unselectable.
|
What is the exact model name of that machine?
|
Thank you for your help.
I contacted Acer about the issue. They recommended that I upgrade my BIOS. Unfortunately, the BIOS flash only supports Windows 8. I made a FreeDOS image with a new and older version of the BIOS. I am currently at version BIOS 2.02 My computer upgrades can be found here:http://support.acer.com/us/en/produc...1&modelId=4244 The newer version 2.06 (Windows 8) says it will not run in DOS mode. The older version 1.07 says that it is less than the current version and is protected. I have played with the flags and attempted to disable the version comparison and disable model comparison but I am still having no luck. |

Just trying to understand- What make and model is it? |
Product Family: Notebook
Product Line: Aspire Product Model: Aspire V3-551 The customer rep assured me once my BIOS is updated that the option to disable secure boot will become available. The version that shipped had secure boot locked on. |

Did the representative or tech walk you through it? |
TobiSDG is correct. I need to disable secure boot. The customer representative identified that the current BIOS has secure boot locked and I need to update my BIOS. Since the problem has changed I have created a new thread at http://www.linuxquestions.org/questi...31#post4848831

I have not been successful. |
Update: I manage to flash the BIOS without Windows 8 see my post here.
So the Acer tech lied (surprise surprise). I am currently running the latest BIOS and secure boot is mandatory (no option to disable) if running UEFI. |
hi
If we want to install linux we must disable secure boot first, right? And once this is done, the bios will let us install any distro and we don't have to worry about signed keys. Is my assumption correct? |
