Windows 10: acpiex.sys corrupt

See step 10:
Clean Install Windows 10 Windows 10 Installation Upgrade Tutorials

If your BIOS supports UEFI that's the more recent 'better' option. But then the disk format must be GPT.

 

Ok Upgrade wasn't 'compatible' so have had to go with Custom.
Sorry but I've read steps 12 and 13 couple of times and I really don't know how to proceed and whether this is BIOS or UEFI and whether I should be deleting all these partitions first.

 

If you use Kyhi's disk and Minitool Partition Wizard you can explore (rt click, Explore) each partition you think might contain data you want and so discover whether you want to keep it.

Any partitions you don't want, you can delete.

 

Upgrade does not work booting from USB. As I said earlier the only option when booting from USB is to clean install.

If you have backed up your data then on the same screen as you showed delete all of the partitions. Highlight them one by one (by clicking on them) and then click delete (click on the red "X" underneath) until everything says "unallocated space".

Then click on "Next" and Windows will make the partitions it feels like and you can carry on.

The reason for your issue is (probably) a muddle from your loader thinking it is EFI and your boot files being BIOS (or the other way around). This is fixable but at this point I would delete everything and reinstall as it will be quicker.

 

The fun continues.....
So I deleted all the partitions, installed and everything seemed fine up to the point where it required a restart only for it go back to the Install Now/Repair my computer screen. Clicking Install just takes me through all the same process again; choosing language, Windows 10 version etc. The only difference is now I have 2 nice partitions although when I select Partition 2 to install into it goes back through the same loop :-(
Should I be repairing/doing something else at this point?

 

Hi, I did suggest you try this:

(See my post above). I.e. boot your PC from Kyhi's boot disk/DVD.

It's worth checking the disk is ok before spending a lot of time on this.

Another possibility might be there are still unnecessary partitions on the disk, although noted, you say not.

 

Hi, yeah sorry but I don't have another machine to hand with which to download Kyhi's disk.

I think I'm back on track anyway as I figured that as the USB was first in the boot list that the problem was when it was restarting it was just booting from that again. Seems a bit clunky but on the 3rd attempt, I pulled out the USB stick as it was about to restart and lo and behold it booted to set up.
Think I may have 3 versions of windows now in my new partition but I presume i can clean that up shortly one set up has completed.

 

Just wanted to say an enormous thank you to everyone who contributed to helping me get my computer back!

Ive just finished copying all my files back and everything seems to be present and correct. I realise we didn't really get to the root of the problem and resolve the acpiex.sys issue, but do I mark this thread as Solved anyway?

One final question, now that I'm back up and running, is there a guide on this site to maintaining a healthy computer? Ive tried searching but not really unearthed anything.

Thanks again

 

Your welcome.

Make sure you have backups of the files and or an image. Macrium is very popular.

There's a green solved button at the top.

Maintain your disk image sets, updating routinely.
Keep a simple record of changes made, including imaging dates.
Thus if you need to restore an image you've a quick way to repeat steps subsequent to the image being created.

Suggestions:
Periodically use a program to check your disk (or you can leave it running monitoring SMART params continuously)

Use Ccleaner (I use it before updating my image (but not its registry cleaner- although that is one of the better ones) - logically it would be safer to use it after updating an image!)

Run chkdsk occasionally.

Keep an eye on idle usage of CPU/disk/internet- task manager - occasionally.

Be cautious about making changes.

There have been other threads about loss of a *.sys file- as to why- I can't recall any one reason. Remember storage isn't perfect- hard disks run on statistics and probability not absolute 1's and 0's, for example.

 

Thanks both.
Thread marked as solved.
