Install CentOS dual system under Windows7;
I have been idle at work recently, so I want to use this time to learn Linux. First of all, there must be a Linux environment, so I installed a dual system on my own computer. Because most of the company's Linux has CentOS installed, I also chose this version.
1. Download the installation disk of CentOS.
My computer is 32-bit, so I downloaded the i386 version of CentOS-6.2-i386-bin-DVD.iso?
Note: You should download the hard disk installation version, not the liveCD version.
LiveCD (CD version) is a version that can be run directly on the CD, and you can choose to install it on the hard disk after running.
Bin-DVD (hard disk installation version) is a pure installation version, which is generally recommended, because many software packages have to be downloaded from the network when installing LiveCD, which will be very slow.
After extracting the image file, extract two folders, isolinux and images, and copy them to the root directory of drive C and the disk where the image file is stored.
Note: The disk storing the image file must be partitioned in FAT32 format (because Grub does not recognize ntfs). ?
2. Divide disks
Download DiskTool partition assistant
This tool is mainly used for hard disk partition. You don't have to use this tool, as long as you can partition.
Start DiskTool, select one of your disks, and then click "Create Partition" to divide a hard disk space as the hard disk of CentOS. Click the "Submit" button in the toolbar to restart the computer to make it take effect. ?
At this time, the partitioned disk still belongs to Windows, so we need to separate it from Windows.
Right mouse button computer-> Management->; Storage->; Disk management, find the newly partitioned disk, and right click-> Delete the volume.
3. Multi-system startup settings
After installing multiple systems, it will be more troublesome to start. Therefore, we need tools to manage the startup of multiple systems. EasyBCD is recommended here.
EasyBCD is a multi-system startup management tool, which saves BCDEdit's tedious and lengthy commands.
Start EasyBCD and click Add New Project-> NeoGrub, and then write the configuration.
After clicking the Configure button, add the following lines to the file that appears:
# The name displayed at startup can be customized.
After installing centos 7, I found that the startup items of the installed windows 8 system and xp system were gone. When installing centos, the boot was directly installed in the master boot record, and there was no option to install it into the partition! So after booting with the U disk of pe system, windows boot was restored, and as a result, centos boot disappeared. . . There have been some changes in the new startup manager grub2 of centos 7 system.
First, restore the guidance of centos.
1. Make a startup USB flash drive with centos iso and enter the interface for installing centos. When starting up, do not choose to install centos, but choose the troubleshooting option, and then choose rescue a centos system.
Press tab to select Continue (required), and then select OK.
2. Enter the command line interface, enter: chroot /mnt/sysimage, and then the important step is to install grub2. Execute the following command: /sbin/grub2-install /dev/sda, and restart the system after the installation is successful. This is just to get back the startup item of centos, and the boot of windows will be completed later through grub2.
Second, resume windows startup.
After 1, recovery is simple. After restarting the system, you can open the centos system and realize windows boot through the function of grub2.
2. Open the terminal and execute the following command under root: grub2-mkconfig-o/boot/grub2/grub. conf system automatically finds the boot items of windows 8 system and xp system and adds them to grub.conf menu. In this way, the danger of manually changing files is avoided, and all systems can start normally.
