Dual Images windows 10 and Ubuntu 16 with UEFI

[george1421]

First let me say I don’t have a clue what is going on here, but I think I see a pattern.

Master image creation.

1. Install Windows
2. Install Ubuntu
   System will only boot windows.
3. Use ubuntu repair tool and now you have dual boot.

Capture and deploy with FOG.

1. Windows is installed
2. Ubuntu is installed.
   System will only boot windows.
3. Use ubuntu repair tool and now you have dual boot.

Do I understand the logic flow here?

[Fernando Gietz]

@george1421 Yes. You have understand all well

[george1421]

@fernando-gietz Ok I find this article interesting.

https://itsfoss.com/install-ubuntu-1404-dual-boot-mode-windows-8-81-uefi/

The most interesting part is at the very bottom section Note.

Note: If after installing Ubuntu, you boot directly in Windows, check in UEFI settings for changing the boot order. If you see no option to set the boot to Ubuntu, you need to fix it from within Windows. When you are in Windows desktop, hover the mouse in left corner, right click and select administrator’s command prompt. Then run the following command:
bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi

If you deploy an images that is broken as you say. If you run this command in windows does it fix the problem. This isn’t the solution just yet, but it may be the clue to why.

@fernando-gietz said in Dual Images windows 10 and Ubuntu 16 with UEFI:

W10 desktop appears, where is my Ubuntu? Well, don’t problem, I need to rebuilt the grub. To do it, I use the boot-repair tool

Again this is the point where you loose me. How are you able to boot up Ubuntu and run boot-repair if Ubuntu is not in the boot selection as you say. I am just guessing here but possibly you use the Ubuntu DVD to boot a live system for repair?

I will look into the tool when I get home…

[Sebastian Roth]

@Fernando-Gietz Ahhhh, I see now what’s going on. Will explain when I get home…

[Fernando Gietz]

@sebastian-roth I forget say it I rebuild the grub from Ubuntu live CD

[Fernando Gietz]

I test the changes that @george1421 says and works fine.
The first boot goes direct to W10 but in the next one appears grub menu .

[george1421]

@fernando-gietz Ok if that commands works (sounds like you agree). Then you have a few options.

1. Sebastian can do his magic and see if fog can detect this condition.
2. (assuming your windows image is sysprep’d before image capture) Have fog copy in a setupcomplete.cmd file (or patch your current one) during post install script execution to have Windows run that command via the setupcomplete.cmd execution.
3. If your windows system is not sysprep’d then have the post install script copy a batch file with the command in it, and a shortcut that points to where the batch file will be copied (i.e. c:\windows\setup). Place the short cut in the admin user’s startup directory. Have the batch file that is called delete the short cut in the startup directory once the batch file has run. This method is a bit more messy but does work.

Strictly speaking I don’t see this as a fog issue since it existed before fog imaging. FOG imaging is only putting back what “should be” in place when it detects a windows setup. With that said, you do have a few ways to go about making this work, and without much pain.

[Sebastian Roth]

@Fernando-Gietz The “issue” from my point of view is that your UEFI firmware is going real EFI which is actually a nice thing. But it is causing a problem.

There is a really good resource on EFI here: https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/

On your bog-standard old-skool BIOS PC, […], the very start of the disk describes the partitions on the disk in a particular format, and contains a ‘boot loader’ […]

Ok we do capture the MBR stuff in FOG! But now read on to the new stuff:

UEFI booting: […] it is completely different. […] many UEFI firmwares implement some kind of BIOS compatibility mode, sometimes referred to as a CSM.

Now you see why I think your system goes real EFI. Probably it doesn’t to the CSM stuff. So let’s talk about this:

[…] native UEFI booting […] UEFI boot manager […] can be configured by modifying architecturally defined global NVRAM variables.

So here we go. The boot order/list in real native UEFI systems is not on disk. So far we don’t capture the NVRAM state of a machine as far as I know. This is definitely something we need to add to the todo list. On Windows only systems it’s probably working out fine most times so we don’t see an issue. But for UEFI dual booting systems we need to find a solution.

[Fernando Gietz]

@sebastian-roth I don’t know very much about UEFI, until now the hardware had legacy support and we worked in this mode. But, the new hardware which is coming only support UEFI, then we need to learn to work under this new mode Thanks for the link, I will read it … what a pain!!!

I am not using the new hardware, I don’t know which will be, and to test the UEFI I am using HP 800 G2 eliteDesk. This hardware have compatibility with BIOS legacy.

We will follow with this … waiting…

@fernando-gietz Does it consistently work after using George’s command? (even if you shutdown and do a ‘cold boot’?)

My theory is that if you have Windows 10 Fast Boot enabled it will skip that bootloader and boot straight to Windows, however that only happens if you shutdown -> boot as opposed to reboot. Windows 10 Fast Boot does a lot of annoying stuff like make it very hard (or impossible on certain devices) to get into BIOS during boot.

[george1421]

@quazz Great point!. I have another thread where I’m collecting drive geometry to help the devs understand what typical drive configurations look like. I ran into an issue where I wasn’t able to mount partitions of 2 of my home computers that are win10 EFI systems. I thought something changed in the Fall 2017 creators update to where FOS couldn’t mount the disk. Long story short is was the fast boot that was leaving the partitions marked as mounted and now allowing FOS to remount the partitions.

After I was clued in by Sebastian I turned off fast boot and was able to mount and map the partitions. Very annoying that feature is. Thank you, M$.

@Sebastian-Roth I am reading the info about UEFI. Very interesting!!! Now I know more about what is UEFI and how does it work.

I post the info of the different commands in my test computer:

[Fernando Gietz]

I have deployed twice the computer with the dual image and now the grub appears at the first time O_o

[george1421]

@fernando-gietz OK what did you change? Magic only happens on Television.

[Fernando Gietz]

No, any change. The only change was the bcdedit command (following the tutorial that you attached)

[george1421]

@fernando-gietz Just for clarity and those who will be doing the same as you: Did you run that command before you recaptured the reference image, or did you add that bcdedit command to the setupcomplete.cmd file?

[Fernando Gietz]

@george1421 I have recaptured the image.

• Install W10
• Install Ubuntu 16
• Boot under W10 and run the bcdedit command
• Capture the image

[george1421]

@fernando-gietz Very, very, nice.

You can fix it on the front end and then not worry post imaging. That info will help everyone who need to create a dual boot system. Thank you.

[Sebastian Roth]

@george1421 Although I haven’t tested yet I am fairly sure that the “fix” won’t work.

@Fernando-Gietz Please deploy that image to a completely different machine, one you have never deployed this image to before. I am fairly sure it won’t have the Ubuntu boot menu entry.
