IPCOP – kernel panic-not syncing: VFS: unable to mount root fs

Have you experience kernel panic-not syncing: VFS: unable to mount root fs upon installation of your IPCOP firewall? Here’s some simple tips to overcome this problem based on my experience.

1. Check your primary Hard Drive sata connection.

2. It must be on SATA 0.

3. Run the installation again and your good to go!

There are ways to boot CentOS into graphical Environment. If you just want to overview and explore the graphical interface of CentOS here’s what you need to do,

1. Login as root with administrator privilege.

2. Type the following:

startx

however, this is just a one-time fix and does not change the log in process for future log ins.

To Setup your default boot with Graphical Interface you need to modify /etc/inittab 

1. Login with administrator privilege using su

2. Type the following and hit Enter.

vi /etc/inittab

Once you’re in, you will see the following text:

# Default runlevel. The runlevels used by RHS are: 
#   0 - halt (Do NOT set initdefault to this) 
#   1 - Single user mode 
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking) 
#   3 - Full multiuser mode 
#   4 - unused 
#   5 - X11 
#   6 - reboot (Do NOT set initdefault to this) 
#  id:3:initdefault:

You need to change the default init ID to: 5 (X11)

id:5:initdefault:

Here’s how to do:

– press i in your keyboard.

– change the value from 3 to 5

– press esc in your keyboard

– Hold Shift + Q

– Type wq then hit Enter to save the changes.

– Ctrl + Alt + Del to restart or type reboot.

You’re Done!
