the Enterprise version of the 1.RedHat company 7.0 has been released. Here are the steps to install a dual system under 7.0.

Pre-installation system: WIN7

Second system to install :RedHat Enterprise 7.0

@ Please note:WIN8 System and Enterprise Edition 7.0 are not compatible. After installing 7.0 , theWIN8 system will not get up.

@ First BOIS has been determined to adjust. "Note enable high-speed notebook mode", I was installed with the PXE network, so I have to set up from the PXE network boot.

@ then boot with PXE .

enter this interface after @

@ This is the language selection during the installation process. "Default English"

after @ Enter the main installation screen

@ Configure Time source

after @ back to the main installation interface, go to language selection "add Chinese support"

@ Select the packages that are installed during installation.

" Minimal install is minimized--- do not install graphics, select this

"server with GUI is a graphical option for installation"--- installation graphics Select this

@ Start sub-disk. Be careful here. The dual system below will have a unknow disk group information, that is your windows, do not move. Direct point above check here to create them automatically. "It will be automatically divided for you." You can manually re-tune it yourself. "

Note 1: If you want to set up a LINUX disk group, the dual-system mode may encounter /boot can only be divided into 2M , this time you can only use automatic partitioning method. However 7.0 ,the/boot partition can be divided.

Note 2: The default disk format is XFS, which you like or can choose for yourself, both in the pull-up options.

Here are some of the main file system performance comparison graphs:

Figure A: The left side is the time spent in creating a large number of small files with the same SATA disk on different file systems.

To the right . SSD disk. "Note: red:ext3 Green:ext4 yellow:xfs Blue:btrfs"

Figure B: The time it takes to create a different file system under a large 2TB file.

"NOTE: red:ext3 Green:ext4 yellow:xfs Blue:btrfs"

after the disk is allocated, it is ready to be installed directly. "Do not configure the network, you can start and then configure" when the installation will let you set the ROOT user password and create a system for ordinary users.

@ wait for it to restart after it is installed to enter the Linux system. "is not found in the system selection there is no windows7 option, don't worry, wait for me to slowly take you to fly."

@ Enter the LINUX system and modify the grub.cfg file.

#vim/boot/grub2/grub.cfg
