why can't I create any file where I want it?

Well... probably not.

But I may not be able to help too much furhter without actually seeing the problem first hand.

But you COULD maybe post a screenshot of the list of users on the edit permissions dlg (The one with the check boxes under allow and deny). One with your user highlighted and maybe a second, see if there is a user with a name that has "SID" in it and a LONG number. That would be the old user that actually created all the files and folders. If there is one, click on that and post a screen shot of that.

But once things go off the expected, they become much harder to try to fix over a forum

One major problem with a multi-boot with windows accessing NTFS data drives is that of permissions, especially on things such as System Volume Information & Recycle Bins.

Each system, (be it NT, Win2000, XP Vista, or Windows 7), will create it's own version of these system areas, Windows will combine them into a single tree for each type of system Data, I would advise that the permissions on these areas are skipped when allowing the permissions cascade.

Also as it is normally required that you take ownership on each OS in turn in order to apply permissions, you choose an OS that is likely to be your most used and set the permissions for this OS Last, Thus leaving the Ownership with this OS.

I have operated many systems with multiple Windows OS's and It is possible to get this to work but a fair amount of work is required to sort out the data partition/Drive permissions.

Example Multiple Partition system


Example of UID from other OS

Basically in order to assign permissions on an NTFS file system, you need to be the owner of the file concerned, this ownership flag is the same as all permissions in that it is OS independent, and is stored on the actual data partition as part of the file header.

In a case like yours where you have four separate OS's you will need to boot into each OS, Take ownership of the data partition, as a user from that OS, and then assign the permissions you require.

for example
In OS1 you take ownership and assign permissions, when you log into OS2 you will find that the Owner of the data drive will show as an S......... UID, this is the unique windows User ID for the username that took ownership in OS1, and is not recognised by the OS2. you will need to change the owner to a user from OS2 in order to apply permissions. You will also need to do this for OS3 & OS4.

The ownership will end up as that of the last OS user ID set, which is why I suggested that you leave your primary OS until last as you are more likely to adjust permissions in future in this OS.

Sorry if this is confusing but permissions in multi-OS or Multi-user systems are complicated, I have seen some systems where the one data location was accessed by multiple users from multiple OS's all on one physical system, which is not a pretty sight.

alright guys, a little more help here, please
i know ive been asking for a lot of attention lately, but after finding out that permissions are the the likely cause of all my trouble with w7 ive been looking around and saw others sharing my problem, but no solutions would lead me to ultimate success

adding authenticated users made a lot of the pain go away, but a lot of folders are still being difficult
you see, authenticated users always solve the issue, however sometimes the rule is not applied to all items inside the designated folder and i have to wonder why
to add insult to injury, yesterday i got flat out access denied for each item in the defiant directory, but today i am being ignored
in certain folders permission changes simply dont reach into the subdirectories
what makes it even more curious is that i can enter and change the values in a folder after folder fashion (and then the changes are applied even to the subdirectories), however for folders containing ~1000+ items this is not a feasible option
even tried to use the hidden admin account to do it
i have taken ownership of the folder and checked to include subfolders, still the permission changes are being ignored while ownership is changed properly

why oh why do permission changes not penetrate into subfolders in certain folders?!

this appears to be a duplicate of my problem (or what it used to be back when i got access denied instead of being silently ignored): ACCESS DENIED ( ownership and permission ) (just that i am not tinkering with C:\)
