my sister encripted her hdd without knowing what was doing.
Now Windows can't start and i can't format, delete or do anything.
I start Windows 10 from USB (UEFI) but i can't remove partitions or delete partitions.
I've tried wiith Gparted and is showing me access denied.
If i try to format the disk from Windows setup i'm getting "0x80070057" error.
Using diskpart gives me can't format disk even with override option.
In the BIOS i've disabled the TPM.
Anyone know what can i do more?
