can i restore my ipad using my chromebook

You also have the option to use a Windows computer, but a chromebook cannot have iTunes on it, which is required for the restore.

No, Mac or PC required.

Sorry, but no. You will need a Mac. If you don't have one available to you, try asking a friend or relative. Alternatively, visit your local Apple Store or Apple Authorized Service Provider and they should be able to assist you with this.
