The bootloader is a program that is executed by the BIOS after it completes its tasks of initializing the hardware and performing the POST (Power-On Self Test). The bootloader is responsible for loading the kernel and other necessary files into memory and passing control to the kernel. The bootloader can be either installed in the Master Boot Record (MBR) of the disk or in a separate partition. Some examples of bootloaders are GRUB, LILO, and SYSLINUX. References: LPI Linux Essentials - 1.101.1, LPI Linux Administrator - 102.1

The command that uninstalls a package but keeps its configuration files in case the package is re-installed is dpkg -r pkgname. The dpkg command is the low-level tool for installing, building, removing, and managing Debian packages. The -r or --remove option removes an installed package from the system, but it does not delete the configuration files and other data that belong to the package. This way, if the package is re-installed later, the previous settings are preserved. The dpkg command is part of the 101.1 Determine and configure hardware settings topic of the LPI Linux Essentials certification program12.

The other options are either invalid or do not perform the desired task. The dpkg -s pkgname command shows the status of an installed package, but it does not uninstall it. The dpkg -L pkgname command lists the files that belong to an installed package, but it does not uninstall it. The dpkg -P pkgname command purges an installed or removed package, which means it deletes the configuration files and other data that belong to the package. The dpkg -v pkgname command shows the version of an installed package, but it does not uninstall it.
