Questions tagged [boot-loader]

A boot loader (aka bootstrap loader) is the program that loads up the operating system kernel (or another boot-loader), e.g., GNU GRUB, LILO, SYSLINUX, or rEFInd. Use this tag for questions about installing, configuring or trouble-shooting software that is used to load Unix-like operating systems. Questions about boot loaders on Android or iOS devices are generally off-topic and are better asked on android.stackexchange.com or apple.stackexchange.com.
