Windows 8.1 won't boot. Recovery didn't help

[dino85]

Hello!

Desktop computer, ASROCK UEFI, Windows 8.1. x64, SSD disk. disk is healthy..

So BSOD appeard on my computer saying that it encountered a problem. After restart it says: File: \EFI\Microsoft\Boot\BCD. Error code: 0xc000000f. Few times i got different error message: File: \Windows\System32\drivers\ACPI.sys. Error code: 0xc0000242

After trying to recover it with bootrec /fixmbr…fixboot…rebuildbcd… and writing Yes to add installation to boot list it says: the requested system device cannot be found.

I tried making the disk active and it didn’t help. Every solution i found on google end up the the same.

One possible problem/solution i found is that the EFI partition is lost or corrupted and i need to fix/recreate that.

Diskpart says my windows disk has 2 partitions: Partition 1 - Primary-729mb-offset 1024mb… Partition 2 - Primary-232gb-offset 731mb

I don’t see EFI written anywhere and it says all disks are NFTS (btw i have no idea what all those terms mean). In solutions i found most of them have one 500mb partition… i guess that’s that 729mb partition in my case or what?

Any ideas what i have to do without losing everything?

Do you have the install media for Windows 8.1?

Which can be gotten from here

Can you access the system by getting it to boot into safe mode?

Have you attempter a repair install of Windows 8.1?

Is there any data on the drive (picture, documents)?
You can use a Live Linux to copy that info to an external drive.
