Installing the CentOS7 dual system on the computer of the Win7 system

Today in their own Win7 notebook toss Linux, in the middle encountered some problems to this record.

Occasionally playing Linux is installed on the virtual machine Ubuntu, but the virtual machine is not enough to play the real feeling, so this time to install a dual system.

There are a few things to prepare before installing:

1. Set aside disk space on the Win7 for CentOS, in the following steps: Computer--"Right-click Management-" Storage (Disk Management) Select a disk with a larger space
   

   To compress, the display status is available after compression is complete (remember not to allocate the newly compressed disk, I'm having problems here, which makes it hard to identify the assignable disk when installing CentOS). I set aside a 60G disk here (in fact, 10G on the internet is enough).

2. Download the CentOS image file: http://www.centoscn.com/CentosSoft/iso/2015/0402/5070.html This is available from the CentOS Chinese station and has several versions of the file. I downloaded the centos-7-x86_64-dvd-1503-01.iso.

   This size is more than 4G. Prepare a USB flash drive with a minimum of 8G to start (back up the data, you need to format). Download Soft disc Thong UltraISO v9.5.3.2901 Perfect registered version. Through the soft disk to the CentOS image written to the USB flash drive, the specific steps can be online query.

With the above 2 steps we are ready to install.

3. Boot into BIOS setup with USB drive

4. Restart the computer to enter the installation interface, at this time to modify the vmlinuz initrd=initrd.img inst.stage2=hd:label=centos\x207\x20x86_64 quiet changed to Vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sdb4 quiet, here SDB4 for the disk where the partition, may be sdb1, according to the actual situation can be modified ( other methods can be used )

5. After the modification is completed, enter the installation interface. Follow can refer to http://www.centoscn.com/image-text/setup/2014/0728/3365.html graphics and text are very detailed. Since then basically the installation is complete.

After the completion of a problem I encountered again, my win7 boot is not, boot can only choose Linux, unable to enter the Win7. Search on the internet for a long time about the repair win7 boot entry, there are into the PE repair, there are changes in the Linux file. Finally I chose the method is installs the ntfs-3g and the fuse2.7.0.tar.gz, needs to install fuse2.7.0.tar.gz first. These two files (NTFS is not supported by default on Linux) allow Linux to support the NFTS system. Install the General command to install a problem using the./configure is an error that causes neither make nor make install to execute. End-use command./configure--disable-kernel-module did not error, the installation was successful.

Use the command Grub2-mkconfig-o/boot/grub2/grub.cfg to re-detect if an operating system exists on the local hard disk, and then automatically generate a boot menu.

Finally the win7 boot menu comes out.
