¿Acaso no te decidías a instalar Linux y Windows en la misma máquina por miedo a problemas? Pues mira este sujeto, que explica cómo instalar 3 DOS, 5 Windows y 137 Linux en el mismo PC.

¿Te parece poco? Bueno; pues también había instalado la mayoría de los BSD, Solaris y Darwin x86, pero éstos tuvo que llevárselos a otra máquina porque no congeniaban bien con los 145 restantes, vaya por dios.

Merece la pena echar un vistazo a su tabla de particiones y a su menú Grub. Un poema...

Hay que ver qué cosas se le ocurren al ser humano cuando decide dejar de ver la tele
