Install the required software
1. Partition Assistant Pro (required): used to partition the hard disk, to format a portion of the disk into a Linux recognizable ext3 format 2.EXT2FSD (hard disk installation required, CD installation is not necessary): Because Windows does not recognize the EXT3 format of the file system, So you need to use this software to put the Linux installation files on the ext3 disk, if you are using a CD-ROM installation, you do not need this software 3. EASYBCD (required): Used to add and modify startup Item 4. Wingrub (recommended): Used to look at the partition number 5. Dynamic disk converters (as appropriate): Linux can only be installed on basic disks, I am because the first installation error caused the disk to become a dynamic disk, so need to use this, about the concept of dynamic disk, please own Baidu, Generally, the system is a basic disk now. PS: I don't use this 6. Centos-6.5-x86_64-bin-dvd1.iso and Centos-6.5-x86_64-bin-dvd2.iso. If you are installing a 32-bit CentOS system, it is Centos-6.5-i386-bin-dvd1.iso and centos-6.5-i386-bin-dvd2.iso two files.
Windows7 above the preparatory work1. Open Disk Manager: Win logo key +r key to bring up the Run box, enter the instruction Diskmgmt.msc return to the disk Manager. Right-click on the last partition to select the compressed volume,If you don't have enough disk space, be sure to back up the data on that partition.！！！ You can also choose to delete the volume,but to do so, be sure to back up the data！！！ Compress how much depending on your hard drive and how much space you want the Linux system to occupy, the hard disk is recommended above 100G. A portion of unallocated space will appear on the disk after this step is completed, such as: 2. Install the Partition Assistant Pro, create a partition on the disk unallocated space right-click, create a 10GB partition to hold the CentOS 6.5 installation file (CD-ROM installation can skip this step), here the file system explained, If you are installing 32-bit CentOS, you can choose to use the FAT32 file system because the installation file is less than 4GB. If you are installing a 64-bit centos, you can only use the EXT3 file system. In the advanced options, remember to select Create as "Logical Partitioning”。 OK after the main interface select Submit execution.
3. In the remaining unallocated space, create aExt3 FormatThe main partition, the same method as above. Note, however, that you must select Create as in the advanced optionsPrimary Partition, if create as is not selectable as primary partition, the number of primary partitions has reached the upper limit, and one of the following methods can be used to convert a primary partition disk to a logical partition. I completed the 2nd and 3rd steps after the disk situation as follows:
4. Install the EXT2FSD software,Remember to check the following options during the installation process！！！ Otherwise there will be an error (CD-ROM installation can skip this step, if the installation of the 32-bit CENTOS,10GB space format is FAT32 can also skip this step). After the installation is completed in the allocated 10GB disk space right-->service Management, in the popup page point start, and then click Apply. For example, note the Tick option: Then in "My Computer" you can see the ext3 format of 10GB space. 5. (CD-ROM installation can skip this step) will centos-6.5-x86_64- Bin-dvd1.iso with WinRAR or UltraISO decompression, the extracted images and isolinux two files copied to the 10GB partition, and will centos-6.5-x86_64- Bin-dvd1.iso and Centos-6.5-x86_64-bin-dvd2.iso are also copied to the 10GB storage partition. (Install 32-bit centos to place the corresponding file in the partition)
6. (CD-ROM installation can skip) install Wingrub, in the Tool->partition list open page to find the number of the partition containing 10GB: such as: I here is (hd0,5), write down this number, later useful. 7. (CD install can skip) install EASYBCD, open after find add New Entry, point neogrub tag. Click Install and then click Configure.
Add the following to the popup document,here (hd0,5) is the partition number found in the previous step：
Title Install CentOS
Kernel (hd0,5)/isolinux/vmlinuz
INITRD (hd0,5)/isolinux/initrd.img |
Restart after saving.
Start Installation
1. If it is a hard drive installation, reboot and select Neogrub boot to enter. If it is a CD-ROM installation, after rebooting, select priority from the CD-ROM boot and insert the CD-ROM boot from the CD.
2. Step-by-step installation: 1) language selection, above means Simplified Chinese, English is selected by default
2) Where did you put the installation file DVD? (CD-ROM installation selected local CD/DVD, hard disk installation selected HDD)
3) Select the partition where the CentOS disc image is located (typically the X-value of the root (hd0,x) command you just entered plus 1, or x+1). Choose the wrong matter, you can return to the "Installation Method" interface, re-select the image below to start the installation of 4) Select the basic Storage Device 5) region choose their own choice, Asia/shanghai or asia/chongqing. 6) Select the bottom option when selecting disk space in the back to indicate that you want to customize: 7) Start customizing: It is important to select the correct partition to install the CentOS system, which is the primary partition that was previously separated by the partition professional assistant. The format should be ext3, this partition must not choose the wrong, the partition after the configuration of the data will be erased, you can according to the size and format of each partition to determine which CentOS should be installed in which partition. Select the section below the point of Create: (if the create can not be directly point, you can click the Delete) and then the format is used Ext4 Good, the size is as far as possible to use out the points out of all the space: (If you are installed in the U-disk students here do not select the U disk) good, Continue: Here will be prompted to write disk: It is important to change the settings, or he will default to put the boot file to the Windows partition, which will damage the Win7 boot file, causing Win7 cannot start!!! Recommended desktop, this installation is the most complete, complete: 3. After booting into Win7, open EasyBCD and click Remove under the Neogrub tab of the Add New entry. Then add a CentOS 6.5 boot entry, the installation of the CentOS system partition must choose the right: Add entry reboot will be able to enter the CentOS 6.5. 4. The 10GB partition that originally placed the CentOS system installation file can be deleted and returned to Win7, and the disk number may change after this step, resulting in the inability to enter CentOS, in which case it is necessary to repeat the 3rd step above.
Configuration after the installation is complete
There is also a small problem after installation: the time between Win7 and CentOS is always 8 hours apart. The following methods are resolved:
First in System->administration->date & Time, cancel synchronize Date and time over the network
Then ctrl+alt+f2 the quick Switch window to login to the root account (the root account name is root and the password is the localhost password that was set when the CentOS was installed)
Run command ntpdate cn.pool.ntp.org
Run Command hwclock-w
CTRL+ALT+F1 switch back to the desktop interface.
And then go back to the Win7 to set the time there will be no problem!
