I want to reinstall Windows 10 from USB. But my laptop can't boot from usb, although I used to install from usb once. I don't know the matter with it.When I chose boot from usb, Dell Assist ran (picture), then it announced no problems. Thanks for the help.
Thank you for your message. Did you create a bootable disc using the Dell recovery tool or from Microsoft media creation?
I am unable to access the image you have shared.
Have you tried creating a new bootable media to check if you can reset? If not please try this link to create a bootable media.
For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Dell-Sreejith R) & send a private message with the service tag, registered name & email address.
