I am running Acronis Cyber Protect Home, Build 39703, under Windows 11, ver 2H21, Build 21000.376, Windows Feature Experience Pack 1000.22000.376.0 (whatever that means.

I am trying to build a rescue disk using your MVP tool and thus far while the MVP Rescue Disk booted without problem, Cyber Protect Home doesn't load after boot. When I did some troubleshooting, and tried to find the Acronis Cyber Protect Home program on my C: drive, File Explorer told me that my C: drive is unreadable or corrupt. I rebooted normally and my C: drive is fine.

I would note that I followed the instructions on the thread re using the MVP tool with Cyber Protect Home; i.e., I created the required subfolder, copied the required file, and made the necessary registry changes.

Can someone provide advice re making this work? 

Thanks, Bob

Bob, sorry but your new topic here has ended up in the Off Topic forum instead of the one for ACPHO where it belongs.

There is a known issue with Windows 11 and Windows PE media not seeing the OS C: drive correctly which is caused by Microsoft not setting the correct attributes for the GPT partition.

This can be resolved using one of several methods:

The first method can be done in Windows 11 using an Administrator command prompt.

DISKPART> select disk 0
DISKPART> select partition 3
DISKPART> detail partition

Partition 3
Type    : ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
Hidden  : No
Required: No
Attrib  : 0X8000000000000000
Offset in Bytes: 122683392   Volume ###  Ltr  Label        Fs     Type        Size     Status     Info   ----------  ---  -----------  -----  ----------  -------  ---------  --------
* Volume 1     C   Windows11-2  NTFS   Partition     99 GB  Healthy    Boot

DISKPART> gpt attributes=0x0000000000000000

DiskPart successfully assigned the attributes to the selected GPT partition.

DISKPART> detail partition

Partition 3
Type    : ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
Hidden  : No
Required: No
Attrib  : 0000000000000000
Offset in Bytes: 122683392   Volume ###  Ltr  Label        Fs     Type        Size     Status     Info   ----------  ---  -----------  -----  ----------  -------  ---------  --------
* Volume 1     C   Windows11-2  NTFS   Partition     99 GB  Healthy    Boot

Alternatively, you can do the following while in the Windows PE environment:

select disk 0

select partition 3

assign

Assigning a drive letter to the Windows C: partition in the WinPE environment causes the GPT partition attribute to be set correctly.
