UEFI

Please help me understand how to boot from my usb or dvd with UEFI.

I think I enable csm under boot then got to security and disable secure boot.

Then I get lost.
Should I save and exit then go back to UEFI settings and select my new device and hit enter to boot or should this have been done earlier before the first save and exit?

Hello Peter,

If you have not already, the USB would need to be created for UEFI.
Afterwards, I like to boot to my motherboard's boot menu, and select to temporarily boot from the UEFI USB.

Hope this helps.

HI Brink
I think I am asking how to use UEFI to boot anything. For example suppose I have a dvd I want to boot from. After enabling csm and disabling secure boot, what is the next step to allow the disc to boot just like it used to with F12.
This is of course without legacy.

I think with legacy, once you click on it, you can boot as you used to with f12.

So my question is what to do to boot from a dvd after csm and secure boot are attended to?

Thank you - Peter

For me at least, when I boot to the boot menu, I have two options to select from to boot to the UEFI USB or normal (non UEFI) USB for the same USB flash drive.

Same here. My USB thumb drive shows up twice in the boot list. Once with UEFI in the description and once without it. I can then select to boot it up in UEFI mode of not. That's without changing any of the BIOS UEFI settings. I haven't tried booting from a CD of DVD though. I would imagine if the disk didn't support booting in UEFI mode it wouldn't be listed with UEFI in the description. The only reason I can think of to change the BIOS UEFI settings (IE turn it off), is to install an OS that doesn't support UEFI. I am by no means an expert on UEFI though.

The best thing about UEFI is that none of my machines are so equipped.

I dislike it, and the motives behind it, intensely. I had intended to upgrade this laptop early next year, but am not happy about being forced to accept UEFI, so may not bother to upgrade at all. This machine still has plenty of life in it before it's obsolete.


Wenda.

disc not usb

I see where most of the discussion is about usb.
I was thinking if I inserted my OS disc and needed to boot from it.
What do after I disable secure boot and enable csm?

Wenda - I think a lot of people agree with you. Without legacy, and even with it, for an unskilled user like me it is a hardship.

I am asking b/c I was thinking of upgrading but the tutorials I have watched do not tell you what I am asking.

How do you boot with an OS disc with UEFI after you disable secure boot and enable csm?

The same way you normally do I would think, select the Boot option with UEFI in front of it form the boot menu.

I have to play with this more.
Thank you for your help.

I only have one PC with UEFI, my laptop. Being a laptop, it has very basic BIOS options and is limited in what you can change. I only have a very basic understanding of UEFI and how it works. The few times I've done installs on it, I just left it at the factory settings as I'm running Windows 8.1 on it.

hands on

I Understand and I also have 2 pcs both with the older BIS on them which I like. Both are running Win 8.1 which I also like.

I guess one cannot learn all from tutorials and has to actually get their hands on a machine with UEFI.

I understand the reason, security wise, why it is a new system but unless you have legacy or are skilled it will turn most people off, I think.

I just went through a process where I had to keep booting as I was using distros from Linux on a pen drives and cannot imagine what I would do if I had UEFI.

Maybe my machine and I will live long enough not to have to get involved with it. :thumb:

I have Windows 8.1 installed on an SSD, running in UEFI.
I have no trouble booting from a cd or dvd, I booted from it to install Windows 8.1 on this new build I did back in Dec.
CSM was and always has been disabled.

Now I don't know about booting from USB, but I certainly don't have to do anything special to boot from a cd or dvd, I just set the boot order to boot from it first, insert the bootable disc, and it boots from it no problem.

On a lot of PC's, you can't install 8.x in UEFI mode if the USB thumb drive is formatted in NTFS. I can on my ASUS. I use the Windows 7 DVD Download tool to create my bootable install thumb drives. It formats the thumb drive in NTFS. My laptop seems to be an exception to the rule. Most of the tutorials on creating a bootable Windows 8.x install thumb drive will tell you to format the drive in the FAT file system. It's not an issue though when booting from an optical disk as it has its own format.

I must be mistaken about csm as I thought that was enabled and secure boot disabled.
