The easiest solution is to download a pendrive from the official Microsoft site with the media management tool and, once you have it, turn on the AeroBook with the pendrive on and press F7 (Fn + F7) intermittently until a menu of boot selection in which you must choose the pendrive. A Windows installation menu will open in which you must select advanced tools, startup repair. A process will be initiated that will solve the problem of Windows startup.
