Ops, something went wrong

You have three disks with two separate EFI system partitions. Currently you are booting from disk 3. Go into UEFI settings (BIOS) and put disk 2 at the top of the boot order. Or, use the boot override menu (usually F8 or F12) and manually select disk 2 to boot from.

On my desktop computer, whenever I do anything that messes with the default EFI System Partition, UEFI kicks it down to the bottom of the boot priority list and it boots to my recovery partition. I have to go into UEFI settings and move it back to the top of the boot priority list.

On BIOS or Boot menu there is no option for Win 10, only for Win 7 and Lubuntu that are on disk 3.
It is like there is no EFI partition on disk 2 is empty but it is not.
And I can see that BCD was modified after first boot during installation.

Run: DiskParInfo.bat - Click here to go to the BSOD batch repository to download and run this batch file.

(the command runs on windows 10.....not yet tested on windows 7)


If it does not run then run these commands:

Code:

diskpart
lis dis
lis vol 
sel dis 0
det dis
sel par 1
det par
sel par 2
det par
sel par 3
det par
sel par 4

When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread

Unplug either the power or data cable from disk 3 (Windows 7/Linux). Reboot the computer without it connected. You can also try resetting the BIOS to default settings. It is a strong recommendation to disconnect all drives except for the target drive when installing Windows. I don't personally do that, but it can prevent a lot of problems like this one.

It seems like there is a valid EFI System Partition on disk 2 that was created by the clean install of Windows 10 on that disk. For some reason it isn't appearing in the UEFI boot selection list. The Macrium Reflect Fix Boot Problems utility could be tried, just make sure not to overwrite the EFI System Partition on disk 3 or the capability to dual boot Windows 7 with Linux would be lost on that disk.

You also do not need to use a Macrium Reflect Rescue USB. The same thing could be accomplished with diskpart commands after booting from the Windows 10 installation USB flash drive. Delete the existing EFI System Partition on disk 2. Recreate it. Use the bcdboot command to put the BCD back into it.

Solved.
I did what NavyLCDR suggested, disconnecting disk 0 (data) and drive 2 (M.2 SSD - Win 7 and Lubuntu).
The drive 1 (win 10) wasn't showing under BIOS or Boot menu but, for my surprise, it did boot as EFI and proceeded the installation, making one or two more reboots. It ended with ver 2010 (h2) but it wasn't showing as a boot option (although it was booting).
I booted Kyhi Recovery tools and did a boot repair using Macrium reflect as EdTittel suggested and it corrected the problem.

What caused this problem is unknown.

Thanks to all.

@NavyLCDR: might there be some benefit to creating the Macrium Rescue disk and then using its "Fix boot problems" capability? Given the system does a dual boot with a non-Windows OS this wouldn't be the end of repairs, but it might help get things working. It's what I would try (and have used successfully) when in similar straits. Here's a link to that Macrium tutorial: Fix Boot Problems
HTH,

Would there be a log report of findings and or commands / results used during the run?

Awesome! Glad it all worked out for you!
