Windows 10: NTFS Permissions Problems

Good Evening tenforum,

I have a very bad problem with a (or better two) windows installation(s) and it's NTFS permissions.. First I am gonna provide you with all the info and problems I face:

The story:
My dad's pc was very slow on windows 7 on an HDD and so I thought I'd install him a fresh and clean win10 installation on a brand new 512GB SSD.. I unplugged the old HDD and installed win10 on the SSD by using a Bootstick created with MediaCreationTool. Up to this point, everything looked very good and windows 10 booted perfectly and it does so every time. Now I booted again and replugged the old HDD because he wanted to access the data on the old drive while using his new installation.

And here comes the big problem..:
He had no access on his C Drive (SSD, Win10) and also no access on his D Drive (HDD, Win7) up to the point where he has problems starting programs, writing data in specific directories and altering specific files. I cannot say whether or not there is any distinct pattern in the data he cant access but there are multiple.

Things I checked myself:

1. If you boot from the HDD (win7) you have the same issues.
2. The account on win10 is an administrator
3. If you unplug the HDD and boot Windows 10, you have the same issues.
4. I tried altering the owner of the whole C: and D: Drive to PCNAME/Administrator and have the same issues.
--- When I try this, I get a error message for all the files I cant alter the permission on:




(This is not a screenshot of the PC i talk about, because you probably wouldnt understand the language but it has the exact meaning)

So yes, I tried this "workaround" of changing the owner from TrustedInstaller to PCNAME/Administrator of the drive and the problem persists.

At this point, I have no clue what to do next and I am pleased to hear your opinions.
Thanks, John

:)

 

xp ntfs permissions erased - help!

NEVER, ever, remove FULL CONTROL permissions in the Access Control Lists/rights priveleges from:

• Administators Group

• YOUR local Administrator User

• SYSTEM

on NTFS rights on your disks (via Explorer.exe rightclick properties menu, security tab) that use that filesystem, OR in the REGISTRY either, via rightclick on HIVES/KEYS permissions popup menu options...

(Sure way to lock yourself out, period, & I have done it myself early on w/ NTFS filesystems &/or the Registry before... only way to learn sometimes, is making mistakes!)

* Keep this in mind, those of you that start experimenting w/ security @ these 2 levels!

APK

P.S.=> Leaving them @ FULL POWER, in both areas, usually 9/10 times allows you to get back into your rig (logging on as your LOCAL ADMINISTRATOR USER, to fix it), & make alterations to rights/acl's as needed, to "get it right", eventually... especially when you're still learning/experimenting! apk

 

Which permissions override when using Folder permissions and NTFS permissions?

Which permissions override when using Folder permissions and NTFS permissions?

 

Which permissions override when using Folder permissions and NTFS permissions?

I teach this all the time.

The way it works is the most restrictive applies when combining share and NTFS permissions.

What that means is if you share a folder as read and then you set NTFS permissions as read and write you are only going to get read. Because it is the most restrictive when combined.

So basically set your share permissions for your group as full control then use NTFS permissions to create the restrictions.

So if you want a group to be able to read and write but not delete then set share as full control from that group. Then go to NTFS permissions and set explicit permissions for that group to only read and write.

Let me know if you need further clarification.
