It's a Toshiba She thinks they are backed up on her external and has no clue about the image. Her kids have been playing Roblox and thinks it has something to do with that.

I don't think the repair was succesfull. It's been stuck with the name on the screen and the spinning circle for a while now

There was no restore point so I did the startup repair. She tried to do a reset before and it failed

I'm sorry it's my friends computer it's a Toshiba. I did the repair and now it's back at the screen to choose an option: Continue
Use a device
Troubleshoot
Turn off PC

Please help no clue what to do
