Mi computadora portátil venía preinstalada con Windows 8.1.
Configuré el arranque dual. Todo parecía estar bien y accedí a Ubuntu sin problemas después de seleccionarlo en el menú para seleccionar el sistema operativo. Debo agregar que el método de arranque se cambió a heredado.
Sin embargo, desde que uso Ubuntu, ya no tengo la posibilidad de seleccionar el sistema operativo. La computadora portátil simplemente arranca directamente en Ubuntu.
Por lo tanto, intenté acceder a las opciones de recuperación, solo que parece que el gestor de arranque de Windows 8 se ha dañado de alguna manera, ya que ahora me dicen que use el disco de recuperación de Windows 8 (que, como estaba preinstalado, no lo tengo).
Intenté reparar el arranque nuevamente sin éxito. Al reiniciar, solo aparece una pantalla de presentación básica que me pide que seleccione Ubuntu, Memtest, Windows 8 Recovery o Windows 8 Bootloader (los cargadores de arranque nuevamente requieren que inserte el disco).

No hice nada manualmente: el instalador hizo todo (con la excepción de cambiar el arranque a Legacy para permitir el arranque de otro gestor de arranque).

RESUELTO
Supongo que lo que pasó de alguna manera corrompió los archivos y, aunque el Live CD y el USB funcionaban en otras computadoras, esta computadora portátil se negó incluso a reconocer que el disco y el USB estaban insertados, lo que me llevó a enfrentarme al infernal Grub Recover.
Afortunadamente estaba usando un Sony Vaio que tiene este increíble botón ASSIST. Para usar esto, apague la computadora portátil por completo y luego, en lugar de presionar el botón de encendido, simplemente presione el botón ASSIST. Esto obliga a abrir la Consola de recuperación de Sony.
Desde aquí, es posible recuperar el sistema operativo, verificar y reparar el disco duro y también acceder al BIOS... y así lo hice.
En una visita anterior al BIOS, cambié las opciones de arranque a LEGACY para poder instalar otro sistema operativo con Windows 8. Por lo tanto, cambié esto de Legacy a UEFI y verifiqué dos veces el orden de arranque. Luego guardé, reinicié y ahora tengo la opción de seleccionar SO.

Mi sistema Windows no arranca en modo heredado en absoluto; creo que necesitarás volver a encender UEFI para que Windows 8 se ejecute. Si es posible, a veces existe una opción de arranque UEFI/no seguro que funciona mejor para mí.
En lugar de trabajar directamente con GRUB, uso grub-customizerel que maneja casi todo lo que necesito hacer y, dado que lo hace en una interfaz gráfica agradable y sencilla, es mi opción preferida. Una cosa que hace es escanear el disco duro para buscar sistemas operativos alternativos para colocar en los menús de inicio. Puede encontrar las instrucciones para obtener este programa.aquí en los foros de Ubuntu
