Hidden OS creation disabled - Win 10, UEFI/GPT

[Fan_of_Snowden]

Hi Alex,

Here comes an interesting situation. There is a KB4034658 Windows 10 update which fails to install while the NOS was encrypted so I've to decrypt the NOS and install it with success. Meanwhile, I don't want to re-encrypt it so soon as I've nothing sensitive on the NOS and it is my usual operating system. If I remember correctly, while the NOS was encrypted, I can mount it while inside the HOS with password1 correct?

While the NOS has been fully decrypted, I was expecting to see it properly in HOS but Disk management still reports it as RAW. I suspect that has to do with the gpt_enc values right? I do not have any intention at the moment to decrypt HOS and update it so is there a way to create a new gpt_enc to replace what's in the USB key?

I tried to run system encryption test on NOS but still giving the password in HOS failed to mount the NOS partition. Please advise many thanks.

To setup accumulative update it is possible to use the script:

(unhide GPT first)

NOS is RAW - it is strange. Try to check contents of the NOS partition. It can be zero ffiled or random data from HOS. (HOS can restrict access)

Hi, for creating a hidden volume in EFI, is it necessary that the outer volume is a bootable system? In other words: can a hidden volume reside in a data volume as outer (decoy) volume?

You cannot create a hidden volume within the OS partition when using VeraCrypt system encryption for the OS partition. All other partitions you can create VeraCrypt volumes outer/inner for non-OS partitions.
