Windows 10: PC does not boot and Windows repair/installation not working

Hi All,
I am a newbee i this forum, living in Germany Since a few days I am facing a big issue with my PC.
The battery of the mainboard (Asus P8Z77) was empty and I changed it already, but nevertheless the PC does not boot. Most probably the reason for that is a reset of the BIOS setup / UEFI settings.

Original error message in Windows\System32\Logfiles\Srt was
"c:\efi\microsoft\boot\resources\custom\bootres.dll is damaged" (original message was in german language).

First I tried a classical Windows repair, which didn't work.
Then I found an article and created the efi partition new. Worked obviously, this issue is gone. But now I get an error during boot:
"Operating system couldn't be loaded because a critical system is missing or contains errors.
File: \\windows\system32\drivers\wd\WdBoot.sys"

Windows Recovery tools are not working, so I tried a re-installation of Windows. But this didn't work either. System tells me that the C-harddrive is an UEFI drive, which maybe is not supported. So obviously a BIOS setup 0setting still refers to "legacy" instead of "UEFI".

I already checked that in the Boot settings, but everything seems to be correct there.

Anybody an idea, which setting in the BIOS setup could have this impact?

SSD seems to work fine, via cmd I get access to all drives, folders, and files.

thanks in advance

:)

 

why won't windows launch after install new MB and CPU?

To repair windows properly-

• Boot into install CD for XP (if you don't have one, go buy it. For the repair to work, it has to coincide with the version of XP you have).
• Act as if you're going to install Windows, press "install windows", agree to license.
• Wait for it to detect all previous installations of Windows. It will then ask if you would like to repair any of them.
• Select the partition you want to repair, and then go play firsbee...or whatever you do for fun.

Windows 10 random automatic repair after changing boot priority.

Hello. So i have an Windows 10 Pro. Sometimes when i am changing in bios boot order from USB to HDD ( SDD ) windows starts booting with AUTOMATIC REPAIR and then restarting. Is this something with BIOS \ Windows 10 bug related? Tested on pc and on laptop , and sometimes it doing the same.


Situation on PC first,listen:

Few days ago after i change boot in UEFI BIOS from USB to SSD.
Then Windows 10 showed at 1 boot Automatic Repair.
When starting Windows 10 boot loader starts by "preparing automatic repair" and diagnosing pc.
Interesting is that if I restart Windows (after procedure mentioned earlier) it will boot normally. This startup problem was occured only when starting system again after shutdown or restarted pc from windows.So i was needed 2 boots to boot properly to windows.
But on pc, format was needed to remove completely issue and after format is fine.

Pc :
2x8gb Kingston Hyperx 1600mhz DDR3
SSD samsung Evo 250 gb
4790k stock
Asus Sabertooth Z97 Mark 2 with UEFI BIOS


Now laptop with old standard bios:
On laptop i made the same operation, change boot from USB to HDD and on first boot Windows 10 shows Automatic Repair. But it happened once and i cant reproduce. No format was needed.

laptop is very old with 2gb ram

Why on pc format was needed when on laptop not?



Thanks for suggestions.
