Windows 10: Booting from WinPE CD/DVD Whilst in UEFI Mode

Question : How are you Burning the ISO to DVD ??
By Right Clicking ISO and Selecting Burn To Disk ??
Or by Copying ISO Files To DVD Disk ??

 

Kyhi

I learnt many, many years ago that when I download an ISO file it has to be burnt to disk using a program which reconstructs the original layout faithfully. So no, I do not just burn the ISO to disk, I use a program which is capable of doing what is supposed to be done with an ISO. After all what is the point of burning the ISO to disk as an ISO. All you be left with is another copy of the ISO.

One of my disks was burnt to DVD using the program you yourself recommended, i.e. Active@ISO Burner, the other using the ISO burner module of CDBurner XP which has never let me down so far - I have over the years burnt many an ISO to disc and never been let down. The graphic below shows the contents of the disc as extracted (from your ISO) by and burnt to disc by both programs.

Like Kyhi, it's been many years since I have made a bootable DVD/CD, but I remember having to enable special options to burn a specific boot sector on them along with the ISO. Flash drives are so much easier!

 

Neither of the programs I used have any such options, they just burn the ISO as presented to it and if that includes a facility for booting then that get burnt on as well. I guess things have moved on apace since you last used disks. I can't even remember having to select the option to include a boot facility.

 

Every bootable CD/DVD has a boot sector file with an extension .bif. This file must exist in the boot sector of the CD/DVD.
The best program to use to make a bootable CD/DVD is: PortableAppZ: UltraISO 9.7.0.3476 Multilingual
Just run and save it to desktop.

Below is the screen which I open the Macrium Rescue disk ISO.

• Indicates the CD/DVD will be bootable. If not then you must extract a .bif file from another bootable CD/DVD then load it before burning.
• The content of the ISO will be burnt to CD/DVD
• Before burning the CD/DVD. You have the choice to add extra file(s)/folder if needed. Just drag from the bottom Window and Drop to top Window.

The link that KYHI gave you above works perfectly so I think it is your settings in the BIOS. 2 options need to be set:

• Boot order must be set to point to the CD/DVD
• Boot Priority also.

OR: Hit <F12> to accress boot menu for one time boot then you would not have to mess around with BIOS Settings.

Again, same as for USB Stick. From boot menu, there are 2 entries for the CD/DVD: one prefix with UEFI and one without. Since you have the boot mode set to: UEFI + Legacy, booting from either will work.
CAUTION: pay close attension to the screen, you might be asked to hit any key to boot from CD/DVD. If you miss, it will boot straight to Windows.

From your other thread:
Just so you know. Your MB option for CSM (enable/disable Secure boot) in under Windows 8 Feature option. In order to see it, you'd have to enable this option, the default is set to other OS. However, to enable this option, you would need a graphic Card that support this feature, so just leave it to default setting. I have MSI Mother board and it uses almost the same BIOS options as yours. Best not to ask any body because their PC is different from yours, just look in the Manual for the info.

 

Active ISO is just a Burner, no option to set disk as bootable

 

Before I went out this morning I did some checks. I first used my husbands PC to see if the disks would boot up on his PC. They did (he is on an MBR system). I then came back to my PC and checked each disk with the different settings available on my F/W. I tested by setting the first in the sequence to UEFI: <DVD Drive> followed by Windows Boot Manager and the PC went straight past UEFI: <DVD Drive> and booted into Windows 10. I then tried again but setting the first in the sequence to <DVD Drive> again followed by Windows Boot Manager and would you believe it, it went straight into booting from the disk and this happened with both disks.

From the tests related above its pretty much as I thought: if the ISO included a boot sector then that boot sector would be burnt onto the resulting DVD. The problem was that I was trying to boot from them using UEFI: <DVD Drive> rather than <DVD Drive>.

To be honest this is the first time in over 25 years of computing that I have been told you have to choose to make an ISO disk bootable. I've always understood that if the compiler intended the resulting disk to be bootable then the appropriate boot sector would be included in the ISO and burnt to disk whatever program you use to burn the disk and this has proved to be the case this time.

Sorry to disagree with you after all the help you're all offering but that is my experience and I promise that what I've related above is true - both worked by booting using <DVD Drive> - so there is nothing wrong with either disk as I suspected all along.

Here's what you missed. Windows Boot Manager has nothing to do with booting the CD/DVD. It only uses to boot the HD/SSD containing Windows. For example: If you have 2 Windows Installed on 2 separate HD/SSD, You'd have 2 Windows Boot Managers listed in the BIOS and you must set the correct boot order of "Windows Boot Manager" to boot into the version that you want. Here's the screen shots:

Boot order is set to: UEFI CD/DVD: UEFI-TssTCorp....... tells BIOS to look for CD/DVD First and boot mode is UEFI.




Boot Priority is also set to: UEFI CD/DVD: UEFI-TssTCorp .... Tells BIOS to boot from this CD/DVD
NOTE: There's only one CD/DVD in my PC so there's only one entry. But if I have multiple CD/DVD's then I have to select which CD/DVD to boot from

 

Thanks for your response but yes I am already aware that the Windows Boot Manager simply boots the PC into Windows. If I access the F/W without inserting any disk, the options I have are in the following order - 1. Windows Boot Manager; 2. P5: <DVD Drive>; 3. P0: <System Drive>. If I swap 1 and 2 around and try booting I am told to insert a bootable media and reboot. If I now insert Kyhi's disk the following is the boot order I get - 1. Windows Boot Manager; 2. UEFI: <DVD Drive>; 3. <DVD Drive>; 4. P0: <System Disk>.

To get Kyhi's disk booting up, I have to move 3. to position 1. This moves WBM to position 2. and UEFI: <DVD Drive> to position 3. One other thing you should also know is that when I want to boot from a CD or DVD it looks like I have to check the sequence every time otherwise I'm likely to get a result I don't want. What I DO know is that Kyhi's disk works fine if I set the sequence such that <DVD Drive> appears first in the list. If UEFI: <DVD Drive> appears first in the list the disk is ignored and the PC boots into Windows 10.

I'm beginning to think I may have made a bum buy with this mobo but I'm stuck with it now. Anyway, I hope what I've said above makes sense as it is a bit awkward to describe particularly since I don't have any means of capturing a screen shot of my F/W.
