+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Problems may arise on very old or very new hardware due to graphics drivers. If
+the installation hangs during the boot. In that case, you can try adding the
+`nomodeset` parameter. This prevents the Linux kernel from loading any
+graphics drivers and forces it to continue using the BIOS/UEFI-provided
+framebuffer.

+On the {pmg} bootloader menu, navigate to 'Install {pmg} (Terminal UI)' and
+press `e` to edit the entry. Using the arrow keys, navigate to the line starting
+with `linux`, move the cursor to the end of that line and add the
+parameter `nomodeset`, separated by a space from the pre-existing last
+parameter.

+Then press `Ctrl-X` or `F10` to boot the configuration.
