Windows 10: Recreate ASUS F9 recovery functional partition
Recreate ASUS F9 recovery functional partition
As many did, I upgraded my ASUS G751JY from Windows 8.x to Windows 10, and this destroyed ASUS F9 built-in recovery feature. When I press F9 now it will give me a BSOD with:
Your PC needs to be repaired
A required device isn't connected or can't be accessed.
Error code: 0xc0000225
[ A text saying I should use recovery tools on my installation media to fix the issue. ]
Press Enter to try again
Press F8 for Start-up Settings
Press Esc for UEFI Firmware Settings
This happens every time I want to use F9, then every time I have also to repair Windows boot (have no problem, I know how to do this and regenerate a correct BCD), so my idea now is to recreate a generic Windows 10 install partition working with ASUS F9 feature.
Here is my current situation:
but Recovery partition was Disabled.
No problem. I've managed to re-Enable it using the REAgentC command:
ASUS F9 still not working giving me BSOD Erorr 225.

Following some guides on the net I've been also able to create a generic "install.wim" starting from MediaCreationTool's Windows 10 ISO file and "<mounted Windows 10 iso>:\sources\install.esd", using the DISM command:
dism /Export-Image /SourceImageFile:"MY_ESD_FILE" /SourceIndex:1 /DestinationImageFile:install.wim /compress:recovery /CheckIntegrity
How do I proceed now?
- Add a new additional 4GB recovery partition with GUID ID: DE94BBA4-06D1-4D40-A16A-BFD50179D6AC
- copy "install.wim" into this partition (requires a specific dir structure or the root will be enough?)
- use "REAgentC /setosimage ..." and target to the new partition with the wim file
Is this correct? Will this make ASUS F9 work again?

correct - as far as the OS Image Recovery
Not sure about F9
as you would have to regenerate the bootkey
So I don't need a specific directory structure for the install.wim file?
Can I put this in the new additional 4GB recovery partition and just use the usual:
Reagentc /setosimage /path <driveletter>:\<folder-containing-osimage> /index 1 /target C:\Windows ?
You can use the E: drive
copy the install.wim into a RecoveryImage folder
then point to it...
or you can shrink E: and create a RecoveryImage partition...
the install wim has to be in a folder - not on the root of the partition...
ONE MAJOR NOTE...
If you reset the PC your Data partition E: will be removed... So very important that if you reset - you MUST select keep current partitions...
that is the problem with having your DATA on the same Drive as the windows OS
Yes, my idea was to keep the current 470MB Recovery partition and add the install.wim I created from Windows 10 ISO ESD file into a new partition after E: (I'll label this R: ). Something like R:\Recovery_Win10\install.wim
Thank you for the "keep current partitions" hint
You are way better off - not using the Recovery Option at all > with your current disk/partition layout....
If windows ever went bad - just run the windows 10 setup.exe - from within the current windows 10 OS

Known as a Repair Install...
The factory recovery partition more than likely contained an executable file that F9 ran which would then control the restoration. That's why most people when they talk about leaving the factory recovery in place after an upgrade to Windows 10 are likely to be disappointed to discover they can't really use the recovery partition left behind because, more than likely, manufacturer software is going to be required to actually do a recovery from it.
I think the only way you will get F9 functionality back would be to restore the original factory recovery partition.
Let's see if I can find another G751JY user with working F9 so we can discover what's inside the 12GB recovery partition from ASUS...
Honestly I can't remember if I manually deleted the original partition or was wiped out by Windows 8.1 -> 10 upgrade (more likely).

I Recently got a Asus Desktop with F9 recovery, unforuately was too in a hurry to get it setup with 10, to make backup copy of original config lol, my fault I know, soon doing clean install of 10, so think gonna wipe out the partition then, I got a copy of 8.1 Core on another flash drive, Original system key in uefi saved, plus Windows 10 USB drive, and system repair Disk made as well. So think i'll be ok if something ever goes wrong.

I didn't know where else to post this weird one. Did the first Win 10 image on a desktop and noticed a Recovery Partition. On one of two desktops.
Both desktops were installed with Windows 7 Pro oem updated to 8.0/8.1/10 which means it never had a...
