Fixing a boot error
Sometimes when booting a GNU/Linux computer the following error appears:
Intel UNDI, PXE-2.0 (Build 083) Copyright (C) 1997-2000 Intel Corporation For Atheros PCIE Ethernet Controller v.18.104.22.168(09/28/10) Check cable connection! PXE-MOF: Exiting Intel PXE ROM. No bootable device -- insert boot disk and press any key _
The way I found to fix it is to plug a Live USB, launch the boot menu, and then restart the computer. It is not necessary to boot the distribution to make it work.
