Why, when creating a hidden os through VeraCrypt, is the Create hidden os footnote not Active?

Question

System administration

Hello, I'm trying to create a hidden Windows 10 OS through VeraCrypt, but when I enter the program, the faith of the crypts. The footnote system-create hidden OS is inactive and greyed out, what could be the reason?

Faced the same. Installed Win 10, then installed Linux, changed the EFI GUID of the Win 10 partition from Linux, then installed the second Win 10 with a separate bootloader, returned the EFI GUID of the first Win 10, cloned the shared bootloader partition of the second Win 10 and Linux, left only Linux in one, in the second only the second Win 10. One of Win 10 was encrypted by Vera, the second by Bitlocker, and fucked by the difference in speed, Bitlocker turned out to be 90% faster than unencrypted, and Vera was only 50%, but the truth is I have a special config - a fast SSD with a slow processor maybe it will be the same for you.
