Linux and Windows dual-system Installation Essentials

Here are some of the issues that are encountered with the two-system installation of CentOS and Windows7

One, disk partitioning

This has to say in Windows under the pit Dad set up, if the default disk partition, the system will first draw a 100M or so area, the key or primary partition, here to say that the disk partition is up to four primary partitions (p), an extension area (e), (here the sum of P and E is up to four, As for the reason, detailed below) As for the logical Zone (L) is further divided under the expansion zone.

At the beginning of the habitual use of the system with the partition software skilled division of C, D, e Three zones, there is no problem in Windows, and then began to install CentOS when the problem, should have just said over three areas, plus windows own that a partition, total is four p, There is no way you can partition the CentOS installation naturally. Add a word, window7 system in the Disk Management software is a mess ah, because with this, resulting in a disk partition error, the system will not go.

Bump encountered a lot of problems, and finally search on the Internet, and finally to solve the problem, the disk partition in the installation of window7 do not use the graphical interface of the partition software, when the installation program to create a disk partition interface, press "SHIFT+F10" to start the command window. After entering DiskPart Enter, you can enter the command environment of DiskPart (its prompt is: "diskpart>"). You can partition the command by typing it at this prompt: Clean, List, Select, Create, Format, Exit, which you can use to type help at the DiskPart command prompt or through a network query to know , I will not repeat this. Assuming that the target disk shown with the list Disk command is number NO. 0, the steps to establish the partition are as follows:

The following is a reference fragment:

　　 List Disk
Select Disk 0
Clean
Create Partition Primary size=512000
Active
Format Quick
Create Partition Extended
Create Partition Logical size=512000
Format Quick
Create Partition Logical size=512000
Format Quick
Create Partition Logical
Format Quick
Exit
Exit

The command interpretation of each operation step is: Display all the disks of this machine, in order to operate the target disk correctly, select disk No. 0, clear all partitions on disk No. 0, create primary partition, capacity: 512000MB, activate primary partition, quickly format current partition, create extended partition, create logical partition one, Capacity: 512000MB; Quickly format the current partition, create logical partition Two, capacity: 512000MB, quickly format the current partition, create logical partition three, the size of the remaining capacity, quickly format the current partition, exit the DiskPart command environment, exit the command window.

Specific partition of the disk to see your own needs.

Second, the System boot boot

After installing the Windows and CentOS two systems, the key is the system boot problem, here is recommended a window under the good software EASYBCD, can be directly to the official website to download, choose non-commercial version, is free, the function is also very good, in fact, they can also run the CDM to complete, It's just that the software is much more convenient to use. Specific use, online tutorials a lot, will not repeat.
