This article shows you how to install CentOS under win7. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Installation steps of CentOS under win7:

one. Install win7.

1) Partition scheme.

Divided into a primary partition, an extended partition, and then in the extended partition in several logical partitions but not finished, the rest of the space for CentOS installation. The partition scheme on the 230g book is: [50] (main partition) installs 7, [506030 (fat32) remaining 40g for CentOS installation] (extended partition). A disk can only have four primary partitions, and one master and one expansion will take up two, so a hard disk with dual system centos must be installed in an extended partition, otherwise it is always prompted that the partition table cannot be allocated when CentOS installs the partition.

2) solve the 100m hidden partition of win7

Press shift+f10 to call up the command prompt when the partition interface appears, enter diskpart to confirm, and then enter list disk to confirm, it will list all the disks on the machine, assuming that your hard disk number is 0, make sure after entering select disk 0, and there is a prompt 'disk 0 is the selected disk', and then after typing create partition primary size=***XX, you can decide how big it is (the default unit is M, I'll take 30g as an example is size=30726). You will be prompted to say that the partition has been created successfully and that the primary partition of the ok system disk has been created. If you want the hard drive to be in the form of 'main + extended partition', follow the previous steps, type create partition extended to confirm, and prompt 'create partition finished', ok, command prompt completed, exit. Then go to the windows7 installer's default graphics partition interface, click the advanced option to see if there is a 30g main partition above, and there is a blank capacity for all the remaining extended partitions of the hard disk. If ok does not have a large hard disk, it does not matter, click the refresh below to see it. In addition, extended partitions must be divided into logical partitions before they can be used. Let's use this default graphical partitioning tool to subdivide the newly born extended blank partitions. How to divide them is very simple. The button above has already told you. And you have to do as many as you like. When you're done, format each partition, then select the 30g primary partition, and click next, ok,windows7 starts to install automatically.

3) Activation

After ensuring that it is BIOS for SLIC 2.1,

Import the certificate. Run the Command prompt as Administrator, and type

Slmgr.vbs-ilc G:\ certificate name. XRM-MS enter Note: "OEM certificate" and "SLIC 2.1" must match

Import the key. Enter slmgr.vbs-ipk 6K2KY-BFH24-PJW6W-9GK29-TMPWP

Type the "slmgr.vbs-dlv" command to see the complete and specific activation information.

Type the "slmgr.vbs-xpr" command to display "* Activation"!

two. CentOS installation

1) Video card

This is a dual graphics card, now bios is set to use integration only, otherwise you can't play X, when installing win7, you have to turn off the system os dual graphics card switching function.

2) Subarea

/ boot 100m

/ 15g

Swap 2g

/ tmp 1-5g (I did not set this, it is said that it is better to set it because of frequent reading and writing)

/ usr 10g

/ home all remaining

The order is divided from top to bottom, which reduces the number of head arm movement, which is beneficial to disk reading and writing.

3) Software package

Because it is used for learning, choose as many necessary software packages as possible during installation, which will save a lot of trouble in the future. Grub must be installed in linux, when installed with the name of win7.

Summary: follow the above steps, boot, grub boot dual system is normal, there are no problems. There are no all kinds of guidance problems mentioned on the Internet, it may be that the machine is relatively new or the character is good: d

Other additions:

Win7 disabled administrator dislike, you can remove the disabled hook from the computer-manage-user-attribute.

Win7's C disk turns on system restore, but it won't grow automatically if you turn it off in the computer-- properties-- advanced.

The time in the CentOS installation will tick off the UTC that will not match the win7 time conflict.

The above is what the CentOS installation process is like under win7. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
