1.You should have an empty usb flash driver which is better more than 8GB.

2.You should have a software (UltraISO or any other softwares which have the ability to do so) to burn the CentOs7 system to the usb flash driver.

3.A CentOs system also is needed (you can get the .iso file at this CentOS7_DVD.iso).

1.Install the UltraISO software to another computer after you downloaded the UltraISO.

2.Insert the USB flash driver to the computer which you intend to install the centos system.

3.open the computer and F12 (depend on the model of your computer) to the BIOS setup interface. After that,chose the way to run system from your usb flash driver (better in UEFI model).

4.Make sure the computer to identify the usb flash driver , you need to rename the usb driver(like CENTOS).

chose the first option which is "Install Centos 7" after you enter the installtion interface.

Then press "Tab" or "e" to edit the sentence “inst.stage2=hd:LABEL=CentOS\x207... quiet” to

"inst.stage2=hd:LABEL=<usb-driver-name,like CENTOS>"

At the last, press "Ctr+x" to continue the intalltion.

5.So far,So good.

After entering the Centos 7 Installtion interface, following the flow of the Installtion (chose language "English" and chose "GNOME Desktop" in sorware selection).

in "Manual partitioning" section, remove all the file in disks and click "Click here to create them automatically".

6.Done After all this , set the password and username.

7.Reboot the computer

Remember not to pull out the usb flash driver in the first reboot.

After the first reboot,you can pull out the usb flash driver and the centos system is on your computer now!

1. Download drivers (named Nvidia_file.run) from here, and select "Linux 64-bit" option.
2. Update system and build tools.
   

yum update

yum install kernel-devel kernel-headers gcc make

3. Blacklist Nouveau

• Edit /etc/default/grub. Append "rd.driver.blacklist=nouveau nouveau.modeset=0" to “GRUB_CMDLINE_LINUX”
• Generate a new grub configuration to include the above changes.

grub2-mkconfig -o /boot/grub2/grub.cfg

• Edit /etc/modprobe.d/blacklist.conf and append "blacklist nouveau"
  

(Note: if the computer don't have blcklist.conf in /etc/modprobe.d/,you should edit /usr/lib/modprobe.d/dist-blacklist.conf
disable the nvidiafb #blcklist nvidiafb
then append

blacklist nouveau

options nouveau modeset=0

)

• Backup your old initramfs and then build a new one
  

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img

dracut /boot/initramfs-$(uname -r).img $(uname -r)

reboot

4. Install NVIDIA driver
