Windows 10: Boot Error 0xc000007b - acpiex.sys missing or corrupted

I have a Windows 10 Anniversary Update build 1607 and Windows XP Pro SP3 Dual-Boot on my Samsung N150P Netbook.

I had been getting this boot error since few days. I remember plugging a USB drive on my laptop, which was bootable but had no OS extracted there. I booted my laptop while the usb was plugged and the BIOS showed "Invalid disk", so I unplugged the usb and I was booted to boot menu to choose which OS to boot. I selected WinXP and then XP took me to CHKDISK. I did the CHKDISK thing and from what I saw, It removed some kind of files from the disk that had Win10 installed.

After chkdisk, WinXP and everything else worked....except Win10. I now can't boot to Win10. Booting Win10 shows this error code - "0xc000007b" and acpiex.sys file missing from C:\Windows\system32\drivers\acpiex.sys.

I booted to WinXP to check if the file is really present or not, to see it's there. The file is there and all well. But the Win10 still says it's corrupted.

I even tried booting to Win10 install disk and using Startup Repair from there. After waiting for 8 minutes of "Attempting Repair", it still had the error.

Anyone can help me in this situation? I would really appreciate it. Thanks!

Here's the mentioned file's properties dialogue -

Unable to boot Windows 10 - Winload.exe missing or corrupted - error 0xc000007b

Thanks again for help.

Unfortunately the automatic repairs don't work at all. It just sits there doing nothing for hours without a result. I believe I need a more manual approach. Correct me if I'm wrong, but either the winload.exe file is corrupted (I can actually locate it on
the HD drive) or bootmgr is looking for it in the wrong location.

Any idea how I can troubleshoot from here?

I'm also confused why it gives me error 0xc000007b. From what I've read it's usually about software that's incompatible or missing and not a required boot executable like winload.exe .

 

BSOD and 0xc000007b boot error


I'm having an almost identical problem, but I cannot even reach a command prompt. This has been a stable system until this morning, now the BSOD shows that \Windows\System32\Drivers\aswVmm.sys (part of Avast Internet Security) is causing the 0xc000007b boot error... Doesn't seem to be any way around it that I've been able to find. Any suggestions will be much appreciated!
