setting the 'hidden' attribute on a partion from Linux (parted) isnt respected by Windows?
when I set the 'hidden' flag on a GPT partition it's not respected by Windows 8.1 (Windows attempts to mound, throws UI, etc). However if I set the 'hidden' flag from diskpart.exe it is respected - are these two 'hiddens' different?
how can I set the bit from Linux such that it's respected from Windows?

Solution 1:
I am not sure which attribute bits parted uses to define a hidden partition, you would need to look at the source code. But from what you have experienced it must be different.
Microsoft defines these partition attributes for GPT: Bit 60 - Read Only, Bit 62 - Hidden, Bit 63 - Do not automount
For more information see this wiki article.
And how would you do this from Linux? Well you could check the parted documentation to see if allows you to set custom attribute bits for a partition entry; and if not then you would need to modify the source code to have it set the bit microsoft uses as well.
