Acer OS and Recovery corrupted shows error code : 0xc000000f

i have a acer aspire r11 laptop

when the laptop boots shows recovery

error code : 0xc000000f

you need to use recovery tools. if you dont have any installation media. contact your pc admin or pc /device manufacturer

Press F1 to enter recovery Enviroment = loops back again

press f8 for startup settings = one blink then same recovery page settings

press esc for uefi firmware settings = goes to bios / settings is uefi

alft + f10 is not working also for recovery

d2d recovery is enabled in bios

tried to boot an iso windows 10 but reset this pc is not working.

shows error "the drive where windows is installed is locked unlock and try again in windows 10"

tried chkdsk no issue

tried

bootrec /RebuildBcd

bootrec /fixMbr

bootrec /fixboot

= no issue

tried sfc scannow

unable to reset your pc . a required drive partition is missing shows.

i already backup the files via slave. do acer have an oem cd where i can download and perform reset this pc? - thanks

Looks like current os is corrupted.

If you need acer window 10 then you need to contact acer service centre and ask them if they sell e-recovery (window 10)

Btw, You can also install Microsoft Window 10
From Microsoft site

To start System Restore using the Command prompt, follow these steps:

Restart your computer, and then press and hold F8 during the initial startup to start your computer in safe mode with a Command prompt.
Use the arrow keys to select the Safe mode with a Command prompt option.
If you are prompted to select an operating system, use the arrow keys to select the appropriate operating system for your computer, and then press ENTER.
Log on as an administrator or with an account that has administrator credentials.
At the command prompt, type %systemroot%\system32\restore\rstrui.exe, and then press ENTER.
Follow the instructions that appear on the screen to restore your computer to a functional state.

i have reformatted the pc already and download windows via web. but i backup the program files of acer. will this work even if i reformat the pc? should i copy paste the whole folder to c:\programfiles x86 \ then perform system restore? will it work?

im not sure if the office is pre bundled and free for 1 month or a year.
