If you use DISM to export the install.wim file from your 10586 ISO to a new install.wim (using /compress:max to convert it to a usable compression) the wim file you create could then be used as a source for repair.
But your problem booting (if you still haven't fixed it after a week) sounds like something different. If you want to see if Windows will boot, you can create a bootable USB stick with a temporary BCD on it which points to your Windows folder on the hard disk. This lets you see if the issue is your System partition (because you have created a substitute System partition on the USB stick).
If you boot the PC with a Windows 10 install USB or DVD, use SHIFT-F10 to get a Command Prompt from the first screen that comes up. Run Diskpart and then list volume to figure out what letter your Windows partition currently has (it can change in this mode). Also note the letter for the USB stick and replace it with a small stick that you can format.
You can format the USB as FAT32. You have to mark the USB Active with Diskpart if you have a Legacy BIOS, but not if you have UEFI.
If you then exit Diskpart, you can create the BCD on the USB stick. If your \Windows partition is on D: and the USB is F: use these commands (replace C: and F: below with whatever letters you found in Diskpart):
bootsect /nt60 F: /force /mbr ← prepares the USB stick in F: to be bootable
bcdboot C:\Windows /s F: ← creates the BCD on F:, but points it to boot your Windows on the hard disk
bootsect /help explains the options used.
bcdboot /? explains options used.
Now boot your PC from this USB stick. If this USB gets Windows to run from your hard disk, it shows that you just need to fix your hard disk System partition.
