How to make boot entry in CentOS for Windows 10

Whenever you try installing Cent OS, after the installation of CentOS, the windows 10  or windows 8 might have gone missing from the boot table entry.
This is due to one of the reasons

• Since Windows 10 or 8 runs with NTFS filesystem which could not be understandable by Cent OS
• any other booting issues like UEFI or GPT partition issues.

Any how, one can try the first method to get rid of the NTFS filesystem issue.

After installing CEntOS, get it in to the Cent OS and open the terminal and give the command one by one

$] sudo yum install epel-release
or
$] sudo yum install epel-release.noarch

$] sudo yum install ntfs-3g

Depending on the speed of the internet, the above command might take some time to install.

$] sudo grub2-mkconfig > /dev/null

this command will read the windows 10 or 8 partition. Thats it. Reboot the machine and you can boot in to Windows 10.

Here is the image

  and final step is here, execute these commands
$] sudo grub2-mkconfig -o /boot/grub2/grub.cfg

If EFI Mode is enabled, then issue this command

$]  sudo grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

Continue

Wireshark in User Mode

If you are running Ubuntu or Linux Mint, the wireshark may not list all the interfaces except bluetooth. There is a small workaround for enabling all the interfaces within wireshark

To install wireshark
$ sudo apt install wireshark

Checking for all the interfaces
$] ifconfig -a

To check the interfaces shown by the dumpcap

$] dumpcap -D -M (following line is the output)
1. bluetooth0 4 network

Enable the following commands in linux to make it work.

$] sudo groupadd wireshark
$] sudo usermod -a -G wireshark $USER
$] sudo chgrp wireshark /usr/bin/dumpcap
$] sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

$] dumpcap -D -M (following is the output)
