Windows crashed, lost files, and cannot find my 2windows in the boot.

Hi,
my problem started like this, i keep my computer running all the time yesterday i woke up and find out that my machine was off because of the power cut that somehow happened, i turned it on and i find out that after chosing which system to go with, cause i have 2 (win7 and win10) i find out that i cannot logging to my win7 and it took me to the repair, tied the auto repair and restart, same thing, tried to logging to my win10 the same thing, a blue error screen shows up that your system is no longer functioning, so i searched on the internet for some solutions, and one of the solutions it's the windows CD, well that i don't have it, i found an old version that i had before so i tried to repair my windows with it, when you boot in with the CD and click on "repair windows" i found out 2 Windows which basically what should be there, but i couldn't fix my win7 at least cause it kept saying that it's not compatible i think i have windows ultimate and the old version that i have is windows professional, even though i only need to repair the log files i think there's no such differences, i don't know maybe i am wrong, so beside the 2 windows, there was an extra one with 100mb space i think it's for recuperation, i clicked on it and pressed next and it worked i got options like "repair" "prompt cmd" ect so i tried that, but the problem is that now when i try the same thing my windows are no longer showing there, and cannot select them in the boot (vanished), i don't know what i did wrong, i tried a lot of things that i have found in the internet but nothing worked, instead now i am getting the Bootmgr is missing, so i hope someone helps me how to get my windows available again at least so i can repair them, i have pictures that i took with my phone of the errors and fixed that i have faced, now i am using a friend computer, and i don't want to format my machine, i ready for any questions or helps that you can provide thanks in Advance.

Update *********************************
i manged somehow to make my windows apear when turning the machine even in the repair when booting from the dvd, the problem was the bootmgr, fixed it using this command on cmd:
-------> C:
-------> bcdboot C:\Windows /S C:
but now i am having this problem System32/Drivers/nldrv.sys file is corrupt
tried the repair that fixed nothing, the question i hope that you can answer at least please, can i copy the drivers folder manually to my my machine without any problems ?

If your trying to repair win7 with a DVD that isn't the same service pack level that can be part of the problems if you have an old DVD you can slipstream sp1 onto it

Samuria thanks for your replay,
but as i said at first the windows were showing (with the same dvd), and now even when i reboot my machine i can't find my systems, i have the hard disk plugged in on my friend computer, it's working fine, can i somehome copy the log files or at least replace the files manually, that is causing the boot problem

i have faced two problems when i recovered the bootmgr.exe, the first error was the system32/Drivers/oem-drv64.sys (0xc0000428 Windows cannot verify the digital signature for this file) and after fixing it i got the second error, System32/Drivers/nldrv.sys (the file is corrupter or missing), and i fixed both by taking my hard disk to another machine, plugged it and logged in to it with that machine that have system worked (windows 7), deleted both files and it works like a charm.
