Solved UEFI and Windows 8 Pro DVD

Hi there, just a quick question about UEFI installation. I've got the Windows 8 Pro DVD but I lack USB Flash Drive 4Gb, is it possible to install Windows 8 with UEFI support with the DVD support or as written in the tutorial the USB Flash Drive is mandatory?

Welcome to EightForums.

as written in the tutorial the USB Flash Drive is mandatory?

I think theog refers to the the tutorial you are talking about. Check out this quote from the tutorial: "1. If you have not already, you will need to create a Windows 8 installation bootable USB flash drive for UEFI from either a Windows 8 installation ISO or DVD."

Use of the word "need," as I think you recognize, should imply that you cannot "install Windows 8 with UEFI support with the DVD." Nevertheless, I don't know why you can't and wonder, as you apparently do, why not. I do not understand theog's explanaton. But, I would like to.

No where in the EightForums tutorial is the use of a USB Flash Drive mandatory,

Some of the confusion comes from a DVD being created through the Windows 8 Pro Upgrade download was not configured to be UEFI bootable. If you have a purchased DVD, it should be fine.

Well, OK, then why is the word "need" used in the quote I supplied? Maybe the "need" statement is incorrect. Am I correct that you disagree with this usage?

Of course, I am not the OP. But, assuming you are correct, then that's a great clarification to know about. Thanks.

Sorry about that guys, I wrongly interpreted the sentence quoted by znod : "1. If you have not already, you will need to create a Windows 8 installation bootable USB flash drive for UEFI from either a Windows 8 installation ISO or DVD."

As I finally tried with the boot menu of my mainboard and I found a selection as linked by theog. I was able to install Windows 8 Pro with UEFI support.

Thanks again for your answers and help and sorry for my misunderstanding.

To be clear, we were under the same interpretation of the sentence I quoted originally, right? And, to get things going, you used a purchased DVD, not a DVD created through the Windows 8 Pro Upgrade download, consistent with what Saltgrass said, right?

We were under the same interpretation of the sentence that you originally quoted but I installed with UEFI support using the DVD created through the Windows 8 Advisor Upgrade.

Thanks much. Back to only semi-confusion. In reconciling what all say, I am lead to conclude that use of the word "need" in the quote is incorrect. Your approach is consistent with the snip theog posted.

1) Some Upgrade downloads do not have UEFI support.

Also The MS USB Tool does not work correctly.

2) When using the Windows 8 Pro to reinstall on a PC Preinstalled with Windows 8 core, Windows 8 core will be installed NOT PRO.

Thanks theog. Let's see if I can follow you. I am going to give it a go, but I will have to be very creative and will have to put a great many words in your mouth. I have no reason whatsoever to think that my words will be correct.

I understand what you are saying in 1), but I am not sure why you said it. Are you saying it because upgrade downloads to non-UEFI computers don't have UEFI support?

I went to Can't find the option to burn an ISO disk. Here, I find the app to "Create Win8 iso with BIOS/EFI support from ESD files" (ESD-TO-ISO.zip). Will that app create an ISO with UEFI support regardless of the machine the ESD files were created on? Thus, the ISO could be used to make an install DVD or install flash drive that would have UEFI support.

You say "The MS USB Tool does not work correctly." I don't know anything about a MS USB tool. Are you saying that an install flash drive created as indicated above would work properly, while the MS USB tool would not work properly?

You say "2) When using the Windows 8 Pro to reinstall on a PC Preinstalled with Windows 8 core, Windows 8 core will be installed NOT PRO." That's interesting, but I am not sure how it connects to the earlier things you say.

1) Part of the UEFI support is missing in some downloads.

2) MS USB Tool will format to NTFS, uEFI USB Pendrive need to be format to FAT32.

3) When reinstalling a Preinstalled Windows 8 core with a PRO disc, the key code in the BIOS will be seen, therefore will install the version of that key.

4) NEED, is this OK now.

1. Do step 2 or 3 below depending on what installation Media you are using.

2. If using a Retail 64-bit Windows 8 Installation DVD

A) Insert the DVD, restart the computer, and go to step 4 below.

3. If using a 64-bit Windows 8 Installation USB Flash Drive with UEFI

A) If you have not already, you will need to create a Windows 8 installation bootable USB flash drive for UEFI from either a Windows 8 installation ISO or DVD.

B) Connect the USB, restart the computer, and go to step 4 below.

4. Press whatever key (ex: F11) it shows to boot to your motherboard's boot menu, and select to boot from the DVD or UEFI USB. (see screenshot below)

Getting ready to watch Downton Abbey. I will get back to you on 1) through 3) tomorrow. What you have done on "need" is making almost perfect sense to me--reconciles pretty much all the earlier comments made. But, I am having trouble with:

"3. If using a 64-bit Windows 8 Installation USB Flash Drive with UEFI

A) If you have not already, you will need to create a Windows 8 installation bootable USB flash drive for UEFI from either a Windows 8 installation ISO or DVD."

Given that "part of the UEFI support is missing in some downloads," how would I know I have an "installation ISO or DVD" that is appropriate for use in creating "a Windows 8 installation bootable USB flash drive for UEFI? I would know if I had a "Retail 64-bit Windows 8 Installation DVD," but that's covered in 2). So, otherwise, how would I know that I have an "installation ISO or DVD" that is "proper" for creating "a Windows 8 installation bootable USB flash drive for UEFI?

When you try to install, will not install in UEFI mode.

I can see that; figured that's the answer. If so, in regard to "3. A)," shouldn't the tutorial indicate what you should do if your don't have a retail 64-bit Windows 8 Installation DVD and 3 A) doesn't work. Is there an alternative better than buying a retail 64-bit Windows 8 Installation DVD at that point? In this regard, I assume that if you had a retail 64-bit Windows 8 Installation DVD, then you probably would not be interested in creating the bootable USB flash drive for UEFI.

And, on a possibly related matter, how does the 64-bit DVD (part of the 2 DVD set) that can be ordered during the ISO downloads fit into the picture? Is the 64-bit DVD the same as a retail 64-bit Windows 8 Installation DVD?

Step 7.

And, on a possibly related matter, how does the 64-bit DVD (part of the 2 DVD set) that can be ordered during the ISO downloads fit into the picture? Is the 64-bit DVD the same as a retail 64-bit Windows 8 Installation DVD.

Yes, the same, one is x32 & one is x64.

Right. Forgot that's in there--the other tutorial. Then, maybe that possibility could be brought in earlier--in the context of

1.

2.

A)

3.

A) If you have not already, you will need to create a Windows 8 installation bootable USB flash drive for UEFI from either a Windows 8 installation ISO or DVD. If this step does not work for you, then ....

B)

4.

And, I come back to an issue I raised earlier.

"I went to Can't find the option to burn an ISO disk. Here, I find the app to "Create Windows 8 iso with BIOS/EFI support from ESD files" (ESD-TO-ISO.zip). Will that app create an ISO with [full] UEFI support regardless of the machine the ESD files were created on? Thus, the ISO could be used to make an install DVD or install flash drive that would have [full] UEFI support."

Elaborating, or maybe clarifying, if "part of the UEFI support is missing in some downloads," then wouldn't the same support be missing from related ESD files (or at least some ESD files)? If so, then the "solution" still has a loose end.

In this regard, I still don't understand where downloads that are lacking UEFI support come from. Are they tied to machines not having UEFI or what? How would you know, in principle, whether your downloaded ISO (or maybe the related ESD files) has (have) full UEFI support a priori, etc? Or can you know in advance?

Also, I presume that the ISO's obtained via option 1 here, Windows 8 Upgrade ISO - Download or Create, are not "foolproof" in regard to UEFI support?

Thanks on: "Yes, the same, one is x32 & one is x64." Just being picky, but I assume the answer is the same whether the ISO download was on a 64-bit installed machine or a 32-bit installed machine.

There are many downloads, for start there are
One for each Language,
One for each download server.

The app adds the missing part.


If you order the disc's, you will be sent x32 & x64 DVD's, if ordered on a x32 or x64 PC.
