Hi all!

I've had this recent error with my laptop, it suddenly won't allow me to create shortcuts on the desktop if it was coming from C:/ saying "Unable to create shortcut check if disk is full". There are 2 drives in my laptop, C:/ Which is the OS Drive, an SSD. And D:/ Which is an HDD for storing files. Now I tried changing the ownership of C:/ from Trusted Installer to Me via the Advanced Permissions and it actually worked and I rebooted.

Now I'm stuck at the spinning circle loading screen before the log in screen with the spinning circle at the center. The background color is light grey which is the one I use. I can't access safe mode using F8 or Shift F8

Help 🙁 Any Ideas on how to get this fixed? Its been like this for 2 hours now

Thanks in advance!

 
Solution
If you took ownership from trustedinstaller you would want to reinstall your operating system. Normally you would not be able to give ownership back to trustedinstsaller. If you boot on windows image and give ownership to trusted installer it would be using the same name but the wrong security identifier and it would not work correctly. Ie it would use the SID from the boot disk.
This is when you do one of two things:
Recover from the full disk image you made before this happened
or
Figure out why it is not booting from your OS install media, so you can do a full OS reinstall. And that has nothing to do with a borked up Windows install.


Here's a test:
Create Linux LiveCD. Try to boot from that. If you still see some Windows foolishness on boot, you're not booting from the right device.
 


Okay thanks, i already have a Linux LiveCD so i'll try that. That usually boots fine though, i'm pretty sure i'm booting from the right device, it's just acting like it doesn't contain an OS..and I haven't made a recovery disk unfortunately.

Yeah, i'm definitely booting from the correct device. Got up boot menu by spamming F12 and selected the USB. Now it says An operating system wasn't found.. i'm so confused i downloaded everything officially from microsoft
 
Disconnect your hard drive and try to boot from your USB install media. If it doesn't boot, you have created it wrong.

Download windows install media iso from Microsoft and create bootable USB with rufus. This has never failed me.
 


Then your USB is not created correctly.
