Trouble With the Graphical Boot Sequence
After you finish the installation and reboot your system for the first time, it is possible that the system stops responding during the graphical boot sequence, requiring a reset. In this case, the boot loader is displayed successfully, but selecting any entry and attempting to boot the system results in a halt. This usually means a problem with the graphical boot sequence; to solve this issue, you must disable graphical boot. To do this, temporarily alter the setting at boot time before changing it permanently.
Disabling Graphical Boot Temporarily
Start your computer and wait until the boot loader menu appears. If you set your boot loader timeout period to 0, hold down the kbd:[Esc] key to access it.
When the boot loader menu appears, use your cursor keys to highlight the entry you want to boot and press the kbd:[e] key to edit this entry's options.
In the list of options, find the kernel line - that is, the line beginning with the keyword `linux` (or, in some cases, `linux16` or `linuxefi`). On this line, locate the `rhgb` option and delete it. The option may not be immediately visible; use the cursor keys to scroll up and down.
Press kbd:[F10] or kbd:[Ctrl + X] to boot your system with the edited options.
If the system started successfully, you can log in normally. Then you will need to disable the graphical boot permanently - otherwise you will have to perform the previous procedure every time the system boots. To permanently change boot options, do the following.
Disabling Graphical Boot Permanently
Log in to the `root` account using the [command]#su -# command:
$ [command]#su -#
Open the `/etc/default/grub` configuration file using a plain text editor such as [application]*vim*.
Within the `grub` file, locate the line beginning with `GRUB_CMDLINE_LINUX`. The line should look similar to the following:
GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/root rd.md=0 rd.dm=0 vconsole.keymap=us $([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :) rd.luks=0 vconsole.font=latarcyrheb-sun16 rd.lvm.lv=vg_rhel/swap rhgb quiet"
On this line, delete the `rhgb` option.
Save the edited configuration file.
Refresh the boot loader configuration by executing the following command:
# grub2-mkconfig --output=/boot/grub2/grub.cfg
After you finish this procedure, you can reboot your computer. {PRODUCT} will not use the graphical boot sequence any more. If you wish to enable graphical boot, follow the same procedure, add the `rhgb` option to the `GRUB_CMDLINE_LINUX` line in the `/etc/default/grub` file and refresh the boot loader configuration again using the [command]#grub2-mkconfig# command.
