Installation of CentOS 7 Dual Boot with Windows 7

CentOS 7 Dual Boot with Windows 7

Step-1 Install Windows 7 and Make some Free space for Linux Installation.

 Remark: As I remain free unallocated 25 GB space coz Linux not support NTFS File system.

Step-2 Install CentOS7 below screen showing and Windows 7 Not showing. So We need to Update few Entries for Windows 7 in "GRUB2.CFG file.

Step3-For Dual boot first Check Partition Using Fdisk -l command.

Here harddisk showing /dev/sda  means One Harddisk is installed

/dev/sda1  * showing Windows Boot partition with NTFS File System.

/dev/sda5     showing Linux Installation partition.

You Can also see partition details using cfdisk command in details

Step4 For Update Grub.cfg file

Open Terminal in Administrative mode using su command.

Step5:Open grub.cfg file using vi editor

Step6: Update below mention 5 Line under this line (### END /etc/grub.d/10_linux ###)

####### Windows 7 ########

 menuentry "Windows 7"  {

   set root='(hd0,1)'

  chainloader +1

}

Remark: hd0-If windows install in 1st Harddisk and 1 for Windows boot partition.

Step7:At last Save grub.cfg file by using :wq!

Step8:Now Restart your Linux and check your Boot Menu.
