Linux boot into Busybox - Gave up waiting for root device

One possible fix is to add the rootwait to the boot parameters.

 

1. Add parameter rootwait to GRUB_CMDLINE_LINUX_DEFAULT in file /etc/default/grub:

 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rootwait"

 

2. Run command to update grub:

$ sudo update-grub

 

(Note: Another related parameter is rootdelay.)
