Tengo una computadora portátil de arranque dual con Ubuntu 16.04 y Windows. Mi gestor de arranque es GRUB, tengo una tabla de particiones GUID (GPT) y mis sistemas operativos están instalados mediante UEFI. El orden de inicio predeterminado es:
Ubuntu, que arranca en GRUB
Gestor de arranque de Windows
De forma predeterminada, inicio en GRUB y luego elijo entre Ubuntu y Windows.
Mi problema es que cuando tengo un medio de almacenamiento USB conectado mientras inicio o reinicio mi computadora portátil, el orden de inicio cambia y el Administrador de inicio de Windows va primero y arranca directamente en Windows.

Respuesta1
tengo una laptop deLenovo Serie Gcon el mismo problema que tu. Como puedes ver, este portátil ha sido descatalogado como el mío. Me comuniqué con el soporte de Lenovo y todo lo que tienen que decir es que ya no ofrecen soporte para estas computadoras portátiles y que todo lo que puedo hacer es verificar la documentación. Como comprenderá, nunca comprará una computadora portátil que mencione en la documentación que "Oye, tengo un error".
En mi propia investigación, me di cuenta de que el error esRelacionado con el firmware BIOS/UEFIy no tiene nada que ver con Windows. Supongo que nunca se solucionará, ya que el portátil ha sido descontinuado. Cuando detecta un medio de almacenamiento masivo USB externo, intenta agregarlo al orden de inicio correcto y estropea el orden de inicio de los sistemas operativos instalados.
¡Pero no te preocupes! EnRod Smithla publicación, verásesteenlace, que es una buena manera de resolver su problema. He hecho algo similar con mi computadora portátil.

Esta pregunta no es un duplicado exacto, pero las siguientes preguntas están relacionadas y es probable que contengan una respuesta:
- Windows 8 elimina Grub como administrador de arranque predeterminado
- efibootmanager -o los cambios se pierden al reiniciar
- ¿Cómo puedo reparar la comida? (¿Cómo recuperar Ubuntu después de instalar Windows?)
Quizás también quieras consultar mipágina sobre golpes de arranque.Esa página es parte de mi documentación de rEFInd, pero los principios se aplican a cualquier cargador de arranque, al igual que las soluciones, aunque con ajustes menores a comandos específicos para cambiar nombres de archivos, etc.
Si el firmware cambia el orden de inicio a Windows en respuesta a que conecta una unidad USB, entonces eso suena como un error de firmware. Como tal, una actualización de firmware puede solucionar el problema; o puede que necesites reportar el error al fabricante (y probablemente nunca verás una solución; los fabricantes son malos a la hora de corregir ese tipo de errores).
