As of now i have started learning RHEL 7 so tried to install Linux on the same laptop and thought I could make it dual boot. But dont know where I made mistake please help me. The purpose of this Instructable is to set up your computer to dual-boot Windows 7 and Ubuntu Linux. Dual-booting is a. While you can install Ubuntu to a partition this size, you will typically want more space store documents and applications. 20GB is probably the. Step 8: Change Boot Device (again). If you changed the.

# head grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub2-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### The first thing you will notice is the line “DO NOT EDIT THIS FILE”. It then explains that you need to use the grub2 template file under /etc/grub.d or the grub2 default settings file /etc/default/grub. Default Grub Config File We first take a look at the default grub2 config file under /etc/default. Saint Etienne Turnpike Rar. As mentioned this is where the default config settings are made such as the time before the default menu entry is booted (default is 5 seconds, see variable: GRUB_TIMEOUT). # cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR='$(sed 's, release.*$,,g' /etc/system-release)' GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT='console' GRUB_CMDLINE_LINUX='rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet' GRUB_DISABLE_RECOVERY='true' So let us change the GRUB_TIMEOUT variable to 10 seconds using vi (or any other editor you like). Let’s also add a variable that is not in the default grub configuration which is: GRUB_DISABLE_LINUX_UUID=“true” and save the file.

This last variable will put the absolute device names instead of UUID- i.e. (Note this is for example purpose only, I will explain later on). Now to activate this configuration, you will need to generate a new /boot/grub2/grub.cfg file using the tool grub2-mkconfig. Download Pop Shuvit Mara Bahaya.

Grub2-mkconfig If you run the tool grub2-mkconfig you will see a lot of text (the script that is generated on the screen). A common mistake people make is to think that this will generate and write the config file to disk. This is not so!

The script will only be displayed on the screen, not to disk. (To verify you could now reboot and see if the boot timeout is set to 10 seconds). To write to disk you need to use the following command.

Rerun the configure commando.
