Today I set up my machine for dual boot up with CentOs7 and Windows 8.1 Under the hood. However after install i realised that by default CentOs7 did not provided a dual boot option, leaving windows totally invisible .
I started searching and trying to resolve the issue spent about an hour to jot down the below learning’s
To make windows boot loader appear follow the below steps.
- Start Centos and Launch Terminal ,perform the following command
sudo grub2-mkconfig
> /dev/null
I was sure that the
windows partitions are not anyhow visible .
- I disabled packagekit as it was occupying the yum using this command , this disable it permanently.
system disable packagekitd
- Once the yum is available for action I performed the following commands
yum install epel-release
yum install ntfs-3g
- Now rerun grub2 make
sudo grub2-mkconfig > /dev/null :
it should
show the windows partition.
- Once the windows partition is available it’s good to save the existing grub.config
sudo cp
/boot/grub2/grub.cfg
/boot/grub2/grub.cfg.backupoldfile
- Now a new configuration file can be created and saved
sudo grub2-mkconfig –o
/boot/grub2/grub.cfg
Reboot your machine and now dual boot should be available
with windows.
