-    * Add a ext4 partition and mounted as /boot (1024MB)
-    * Add a ext4 partition and monted as / (rest)
+    * Add a ext4 partition and mounted as `/boot` (1024MB).
+    * Add a ext4 partition and monted as `/` (rest).
+    * Select the `/boot` partition as a target for GRUB installation, otherwise the system won't boot.

 11. Shutdown and remove the USB Drive
 12. Start again using the option key. Select the new efi boot.
