How to install Windows 10 & OEL 7 dual boot

How to install Windows 10 & OEL 7 dual boot

For me these steps were not working in UEFI mode. So I disabled UEFI mode on my Desktop.

1. Performed Windows install normally.
2. Ensured that I have some space in one partition
3. After this installed OEL 7 normally 
4. Unlike OEL6 , OEL 7 does not have the mechanisam to detect windoes partion and create a grub entry

For this you have to install ntfs packages first

Step-1 (Enable EPEL Repository)

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -ivh epel-release-latest-7.noarch.rpm

Step-2 (Install NTFS-3G packages for enabling support for NTFS file system)

yum install ntfs-3g -y

Step-3 (Enable NTFS support for file managers)

yum install ntfsprogs -y

After installing the above packages 

sudo grub2-mkconfig > /dev/null

... you should see the windows boot listed. If the other entry / entries are OK, go ahead and write it.

If Windows was listed in the previous step, go ahead and save the new configuration file. Make a backup first, just in case.

sudo cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.old

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Reboot the machine and you should see new Menu to reboot to windows
