There are a couple of lines you can make changes to. One is named "hiddenmenu" . Put a # at the start of the line, and when you boot up, Grubs menu will be shown, showing you all available kernels. Also you can change the "timeout" line. changing this from 5 to 30 will give you more time to choose which kernel you want to boot. If you are using Apt for getting updates to the system, apt-get update, followed by apt-get dist-upgrade, all kernels will be saved to Grubs menu. If you are using Yum, it only saves as default, the 2 latest kernels. You can change this behaviour by editing /etc/yum/pluginconf.d/installonlyn.conf . Just change the line "enabled=1" to "enabled=0" . This will disable the plugin, and subsequent kernel updates will all be saved to Grubs config file, and will show up on Grubs menu. All the best.
