? 4, Windows System Preparation

1. Partitioning

If the ISO file is no more than 3.99GB, partition an ISO file broker that is 6-7GB, the file format is FAT32 windows and Linux are mutually recognized.
If it is greater than 3.99GB, what is required? Use the 7-8GB file format for the ext3 partition (this belongs to the Linux partition). You can't see it under Windows! ）

Allocate up to 30GB of unallocated hard disk space (partition helper to do) according to actual needs, ready to install CentOS.?

2. File Preparation

Copy the CentOS DVD ISO file to the FAT32 disk (ext3 disk), and extract the Isolinux and images folders

3. Boot Path Preparation

Start the EASYBCD software, add new entries, and configure

?
Last Click "Configure" to configure the boot drive (USB drive) Location

The code in the diagram is also written like this:

Title Install CentOS 7.0

Root (hd0,2)

Kernel (hd0,2)/isolinux/vmlinuz Linux repo=hd:/dev/sda3:/

Initrd/isolinux/initrd.img

Explain: Here is the most error-prone place, if not written, Linux can not load the hard disk, will eventually jump to "dracut:/#"?

How to write the right, first in the Windows system with Wingrub to look at the partition list

?
Example: Figure (hd0,4) is the drive where the ISO file resides

If you follow the partition drive table in the diagram, then (hd0,2) in the preceding code (hd0.4),

Sda3 to be written->sda5. You see the rules. If you have two or more hard drives, change
is the number \ letters behind HD and SD, such as the first partition of the second hard disk is represented as (hd1,0), SDB1, respectively.

In my case, the disk where I put the ISO file is partitioned into the ext3 format, the seventh partition on the second hard drive,
Using Wingrub to see its partition number is: (hd1,7), my configuration file is written like this:

? Title installCentOS7.0

Root (hd1,7)

Kernel (hd1,7)/isolinux/vmlinuz Linux repo=hd:/dev/sdb8:/

Initrd/isolinux/initrd.img

Configuration complete, restart the computer ready to install!?

? 5, installation

1. Reboot, boot option select Neo Grub Loader

? 2. Go to the CentOS installation file loading page, press B to execute

3. Go to the installation page?

? 4. After selecting the free hard drive area for the CentOS partition, you can choose the automatic partition directly, select the custom installed application, set the root user password and so on.

?
Careful selection of minimal installation, or only the terminal command line interface

?
Choose the GNOME desktop, which makes it easy for beginners to use

?
With the free disk as a CentOS partition, you can directly select the automatic assignment

?
Setting the root password and creating a new user

?

5. The installation completes the reboot.

6. If the CentOS is not loaded after rebooting, could it be? The grub boot of CentOS did not successfully overwrite the MBR of Windows
(This is supposed to be a CentOS boot, and Windows loses the boot menu!) ）。
This is the time to restore the CentOS boot. Actually need to use the software we have downloaded, or EASYBCD,
After entering windows, start EasyBCD,
Add new entry->linux/bsd->type: Select Grub2,name: Write Yourself, drive: Select the boot disk of CentOS

? 7. Reboot, enter CentOS if displayed: License information please follow the instructions below.
Reboot into the system! And it's a dual system of Win7 and CentOS!
