Hi Lana,
No problem, and you did the right thing by stopping and asking.
Please don’t type the second command yet. While the first command is running, PowerShell usually will not let you type anything else.
If it has been stuck at 64.1% for a very long time, you can close the PowerShell window, restart the PC, then open PowerShell as administrator again and run the first command once more.
If the first command finishes successfully, you may skip the next command for now and continue with the remaining Start/Search repair commands. Please run only one command at a time.
If it gets stuck again or shows an error, stop there and let me know. Don’t worry, this should not remove your files.
