Windows 10: Lost all permissions for my Local Disk.

I had been looking around in the properties of my Local Disk, and I hit the security tab. I went into advanced, and I was messing around for a bit, when I accidentally took away all permissions of the local disk from the everyone group. I am not able to access the Local Disk now, and if I try to give myself the permissions back, it tells me that I do not have permission. Somehow this stopped me from getting into safe mode, as whenever I try that, it goes to a black screen with my cursor after login. I was trying to go into safe mode to access the built in administrator, but I don't think that would have worked. I have no idea how to get my permissions back, and I need help.

Recovering Local Disk

Thank you for your quick response.

It could be a compatibility issue with the latest update and your local disk. We suggest updating your disk driver. Follow these steps:

• On the Start, type Device Manager.
• Locate and select Disk drives.
• Right-click on your disk drive, select Properties.
• Go to the Driver tab and choose Update Driver.
• Once done, click OK.

Update us with the outcome so we can provide further assistance.

 

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!

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
