LinuxQuestions.org - [SOLVED] booting problem

- - booting problem (https://www.linuxquestions.org/questions/linux-newbie-8/booting-problem-4175558777/)

My box is Centos 7.1 x64 and every booting I got this problem as shown int the attached photo.

I want to boot the fourth item at the photo, but it boot another.

Please let me know how to boot the fourth evertime.

Thanks in advance.

You should not be booting the rescue every time. That should be booted to fix something and then boot normal.
Why are you wanting to boot rescue ever time?

Edit /boot/grub/grub.cfg and change the default entry from 0 to 3. On Debian the line you need to edit looks like this:

set default="0"

which you would change to:

set default="3"

The CentOS code may not be exactly the same but it will be similar.

...and just for the record, both previous answers are the 100 correct ones.

There is not "/boot/grub/grub.cfg", but "/boot/grub2/grub.cfg".

Well, then edit the /boot/grub2/grub.cfg file as explained above in post 3. Some Linux distributions name the grub directory 'grub', some name it 'grub2', some have both a grub and a grub2 directory. You could also edit the /etc/default/grub file by setting the line at the top of the file to below and then run sudo update-grub

I've changed The content of "/boot/grub2/grub.cfg" like this;

Code:

set pager=1



if [ -s $prefix/grubenv ]; then

  load_env

fi

if [ "${next_entry}" ] ; then

  set default="${next_entry}"

  set next_entry=

  save_env next_entry

  set boot_once=true

else

  set default="${saved_entry}"

fi



if [ x"${feature_menuentry_id}" = xy ]; then

  menuentry_id_option="--id"

else

  menuentry_id_option=""

fi



export menuentry_id_option



if [ "${prev_saved_entry}" ]; then

  set saved_entry="${prev_saved_entry}"

  save_env saved_entry

  set prev_saved_entry=

  save_env prev_saved_entry

  set boot_once=true

fi



function savedefault {

  if [ -z "${boot_once}" ]; then

    saved_entry="${chosen}"

    save_env saved_entry

  fi

}



function load_video {

  if [ x$feature_all_video_module = xy ]; then

    insmod all_video

    insmod vbe

    insmod vga

    insmod video_cirrus

  fi

}



terminal_output console

if [ x$feature_timeout_style = xy ] ; then

  set timeout_style=menu

  set timeout=5



else

  set timeout=5

fi



set tuned_params=""

        else

          search --no-floppy --fs-uuid --set=root b93fcea5-125e-4c36-81b3-2d8b1076803d

        fi

        initrd16 /initramfs-3.10.0-229.20.1.el7.x86_64.img

}



if [ -f  ${config_directory}/custom.cfg ]; then

  source ${config_directory}/custom.cfg

elif [ -z "${config_directory}" -a -f  $prefix/custom.cfg ]; then

  source $prefix/custom.cfg;

fi

Deleted 3 menuentries without the top one.

And it works.

And it works.

Until something overwrites grub.cfg, for example when you update your kernel.

You aren't supposed to change grub.cfg directly. Instead, modify /etc/defaults/grub and run update-grub. Find instructions on gnu.org.
