For example, if you notice ACPI errors, try booting with the '''acpi=off''' boot option. For a full description of these options, refer to the [[https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html|kernel parameters]] document. + /!\ Please note, stating the boot didn't work is not enough for a developer to review the problem.

You are put into the initramfs shell in an effort to allow you to recover the system. Hopefully, if you boot with the '''quiet''' and '''splash''' options removed you will notice error messages before being dropped into the shell which will help debug and direct you to a solution.
