CentOS6.4 and Windows8 dual system installation graphic tutorial

Recently, I upgraded my laptop from Windows 7 to Win8, and installed CentOS6.4 (64) to achieve dual-system coexistence. I had a hard time, mainly because the two iso files of CentOS6.4 (64) add up to 5 GB (in fact, only the first iso is used. both of them are used here, in order to meet some special requirements for the CentOS system), Some problems need to be solved when a hard disk is installed without a CD. NTFS files recognized by windows

Recently, I upgraded my laptop from Windows 7 to Win8, and installed CentOS6.4 (64) to achieve dual-system coexistence. I had a hard time, mainly because the two iso files of CentOS6.4 (64) add up to 5 GB (in fact, only the first iso is used. both of them are used here, in order to meet some special requirements for the CentOS system), Some problems need to be solved when a hard disk is installed without a CD. The NTFS file system recognized by windows can store a single file system that exceeds 4 GB and can be used to store images. However, NTFS cannot be identified when CentOS is installed, and FAT32 can be identified when CentOS is installed, however, the maximum size of a single file supported by FAT32 is 4 GB, so the EXT3 file system is used here. Now, let's take a look at the process. this is only one of the many methods:

Environment:

Windows8_x64 system

Requirements:

CentOS6.4 _ x64 images can be downloaded from this site. Http://www.centoscn.com/CentosSoft/iso/2013/0720/371.html

EasyBCD is a useful tool for setting multi-system boot.

EaseUS Partition Master is a very powerful disk partitioning tool that can format partitions into EXT3, NTFS, FAT32, and other formats.

Ext2Fsd can read and write EXT2/3 file systems on Windows.

Steps:

1: merge the two downloaded image files into one

On the Windows DOS interface, run the following command:

1. Copy/B CentOS-6.4-x86_64-bin-DVD1.iso + CentOS-6.4-x86_64-bin-DVD2.iso

So the two images are merged into the CentOS-6.4-x86_64-bin-DVD1.iso.

2: install the EaseUS Partition Master software and Partition the disk. you can Partition it as needed. before formatting, make sure that important data has been backed up. the partitioning method is as follows:

C: Windows system disk

D, E: some Windows software is installed.

F: The format is FAT32 (EXT3 is used when CentOS is installed). it is used to mount the root directory of CentOS. The size is 67 GB.

H: The format is FAT32 and used as the swap partition of CentOS. The size is 1 GB.

G: formatted in EXT3 format, used to store CentOS-6.4-x86_64-bin-DVD1.iso, 20 GB in size

(Do not forget to click Apply to make the partition take effect after editing)

3: install Ext2Fsd to read and write the EXT3 file system on Windows. After the software is opened, it is displayed as shown in:

Right-click the EXT3 partition and select the configuration file system to edit it as follows:

Click Change and exit to view the EXT3 partition on Windows.

4: Copy the CentOS-6.4-x86_64-bin-DVD1.iso to the G disk, that is, the above EXT3 partition, and use the decompression software such as 7-zip to unzip this image to the G disk, must be the top Directory of the G disk, instead of under the CentOS-6.4-x86_64-bin-DVD1 directory.

5. install the EasyBCD software and configure the boot guide for multiple systems:

The following figure shows how to start EasyBCD:

Click Add new entry and edit the path named CentOS in ISO with the path of the CentOS-6.4-x86_64-bin-DVD1.iso. As shown in:

Click Add entry. the software automatically adds a CentOS startup item. click View settings:

6. restart the system and select CentOS:

The following will go to the familiar CentOS installation interface. the installation of CentOS will not be detailed here, but there are several points to note:

1: when selecting the installation method, select install from hard disk

2: when selecting a partition, you need to select the partition where the iso file (that is, the above G disk) is located. you can view the partition through the software, but you can also try it one by one, no software is installed here, and/dev/sda7 is the selected partition:

3: Select custom installation:

Format H disk as swap partition and format F disk as EXT3 for mounting the root partition. If you are not sure which disk is H or F, you can determine the partition size:

4: After the installation is complete, edit the/boot/grub. conf file in CentOS. the original file is as follows:

Here, title Other refers to windows. you can change Other to Windows. if default is set to 0, it is started by default.

In Centos, if it is set to 1, the following Windows system will be started; you can change timeout to 15.

5. enable EasyBCD in Windows and delete Centos from the editing guide menu.
