acpiex.sys corrupt

Sorry I can't follow the correct posting procedure but I am unable to get past the automatic repair loop.

I can't Reset, can't restore, can't restore from either a usb or a disc and I can't seem to get it into safe boot.
Whenever I try the startup repair, it fails and spits out the Srt Trail log thing. When I plug that into command prompt it gives the following error each time.
If anyone can help I would very much appreciate it
Its a 64 bit Lenovo g580 if that helps

Thanks

Can you get to a command prompt at boot?

If so you could try option 1 here to repair the file

Run SFC Command in Windows 10 Windows 10 Customization Tutorials

Find a flash drive that you can format.
Create a bootable windows 10 iso: Download Windows 10

Correct or confirm:
You are able to enter the computers (windows recovery or advanced troubleshooting menu)
reset with save files or reset with remove files has failed
restore has failed
startup repair has failed

What happens when you click startup options?
Does it let you restart?
Is that why you cannot get to safe mode with command prompt or safe mode with networking?
Do you never see the menu to select #6 safe mode with command prompt or can you see this option and then it does not load?

Do you know the Lenovo F key to boot to a device?
Or did you enter the bios and change the boot order to boot to the USB?

Can you boot to a bootable windows 10 iso using the F key method?
Can you boot to a bootable windows 10 iso using the bios boot order method?

Acpiex.sys is corrupt: That is a windows driver.

For Lenovo F12 should allow you to boot to a device: choose boot to USB hard drive
For Lenovo F2 should allow you to boot to the bios and change the boot order. However you should not need to change the boot order if you can boot to a device using the F12 key.

Hi, thanks for the help so far.

running diskpart and list volume, I'm not 100% sure which drive is which but as you can see from the image, no matter which combination I try, I just get "Windows Resource Protection could not perform the operation".
Ive tried restarting and rerunning a few times as suggested, but I can't determine if fast startup is off or not and nor can I turn it off via the prompts in the other link as I just get not supported.

Running Dism also fails with:
Error 50 Dism does not support servicing Windows PE with /online option

Scanfile returns "Windows Resource Protection could not perform the requested operation"

Finally findstr comes back as not a supported command or else system cannot find then correct path

So you are able to boot to a windows 10 iso and open command prompt with X:\Windows\system32\cmd.exe

Had you tied all of the windows advanced troubleshooting options available in the windows 10 iso?

Did they all fail?

Have you tried the registry backup repair?

Hi,
Ive tried creating a usb drive with the ISO from an old xp machine and from a Mac and both times it didn't work. I could see the flash drive in the BIOS screen and in the "use a device" screen but when I select it or change boot order to make it first, nothing happens and it goes back into the repair loop. A friend is currently downloading windows 10 using a windows 10 machine for me and the creation tool so maybe this will mMe a differences?

Reset fails, Restore failed with both restore points I originally had although system now seems to have deleted them. Startup Repair also fails but points me to the log file where I get the acpiex.sys error

Startup setting allows me to restart but no matter which number I then choose (and Ive tried them all now) nothing seems to happen other than going back into Preparing Automatic Repair loop.

I believe f8 is the safe mode short cut for Lenovo but neither holding it or tapping rapidly when restarting seems to work, and yes have tried booting from both usb and dvd via f12 and changing order in f2

This is the registry repair method. It must be followed meticiously:

1) boot to the Windows 10 iso
2) it may take 5 minutes displaying the windows icon
3) Use the default settings for language, time, currency, and keyboard
4) click next
5) In the left lower corner click Repair your computer
6) click troubleshooting
7) click startup repair (it is expected to fail)
8) click system restore (it is expected to fail)
9) click command prompt
You should see a pop up with title bar: Administrator: X:\windows\system32\cmd.exe
This is the registry backup method:
For each step you must see sizeable file sizes for this to work.
If you see zeros the method will fail.
The command: dir
will be used each step to make sure you are in the proper location and check the size of the files
10) type: C:
11) dir
12) type: D:
13) dir
Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer.
The proper drive will display: perflogs, program files, program files (x86), users, windows, etc
14) type or copy and paste: cd \windows\system32\config
It should display: C:\windows\system32\config>
15) type: dir
It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
All of the file sizes should be sizeable. If it displays zeros then abort.
Make a new directory and name it backup or something similar.
16) type: MD backup
Copy all of the files into this new directory.
17) type or copy and paste: copy *.* backup
It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
Change the directory to regback
18) type: cd regback
It should now display: c:\windows\system32\config\regback>
19)type: dir
It should display: default, sam, security, software, system etc
All of these files must be sizeable. If it displays zeros then abort.
20) type or copy and paste: copy *.* ..
It should now display:
DEFAULT
Overwrite ..\default? (yes/no/all):
21) type: a
It should now display: sam, security, software, system and that the files were copied.
22) type: exit
23) click turn off your PC
Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.

I can access command prompt from the Windows RE and yes I've tried all options in advanced troubleshooting.

I think I did try the regback but it also failed

Sorry crossed posts. Your directions above, that is reliant on me being to access the recovery ISO on a flash drive though isn't it? As so far I have been unable to although fingers crossed the version created using the media creation tool might have more luck later
