CentOS 7 Network Manager not present and wlan0 doesn't exist


I've been running CentOS 7 on this Sony Vaio: 64-bit Intel i5, for about 3 months and the network manager and the wifi's functionality has been good.

I deleted the Win's 7 partitions in order to install Debian Jessie.

Strangly so; upon the first boot into CentOS after the Debian installation my Network Manager and the wifi connection was hosed/gone.

Running dhclient wlan0 returns:
Code:
Can't create /var/run/dhclient.pid:permission denied
Cannot find device "wlan0"
Also, CentOS does not recognize any usb pendrive or memory stick when before the new os was install it did recognize such devices.

When I ran ifconfig -a "wlan0" isn't in the list with lo.
I tried to start the network by running /etc/initid/network start:
Code:
No such file or directory
http://s1052.photobucket.com/user/Ul...55327.jpg.html

Yum is not working either because it can't establish a connection to the repo.


How do I fix this?

I can't boot into CentOS at all now-

It's in konsole mode only with this message:
Code:
Entering emergency mode Exit the shell to continue Type "journalctl" to view system logs
#
I took a picture with my table to show you what is on the screen:
http://s1052.photobucket.com/user/Ul...minal.jpg.html

I can't take any more picture of the konsole on the CentOS side because everytime I turn on the tablet is locks up the Playstation making my roomate angry.
I'll get dmesg and lsmod from Debian.


Paste bin is where I posted the dmesg log-

The module is loaded.
Are you using gnome?
If so go to Settings>>Network
If that works then you just need to restore network icon.
Also since you have debian installed you can mount & access CentOS /var/log/messages or/var/log/syslog through your file manager.
Also you should change your options for your debian terminal to higher scrolling so that you can read more of your messages without losing part of the file or having to use |less or |more.
To do that open Terminal>>Edit>>Profile Preferences>>Scrolling

Yes, I'm using Gnome
When I go to Settings>>Network the only option there is Wired.

-:-CentOS doesn't show in my Debian file manager at all.-:-


The partitions only show in the output of fdisk -l:

Code:

Should I delete that Extended Partition?

I didn't create the Extended partition BTW I think Win's did when I installed CentOS alongside Windows.

Here's a pic of my drive:

I fixed the preferences in the terminal-

No your Extended is your centos OS
You may have to reinstall network-manager-gnome.


Debian has screenshot which you can upload stuff here without having to go to imageshack.
Open your filemanager & take a screenshot.

I found screenshot but don't understand how to add it to a post-

Would it help (since I can't boot into CentOS) to go ahead and flag that extended partition with a flag for it will boot? Maybe try rescue with the Live CentOS DVD? Bad idea?

I'll try where is nm-applet and see what CentOS tells me but it's only running in konsole mode only.

I found this documentation and I'd like your take on it-

I'm wondering if entering into rescue mode and reconfiguring the bootloader is the answer?

CentOS doesn't boot from grub?

To upload a screenshot Select "Go Advanced>>Manage Attachments" then browse file for upload, then upload.

Maybe grub isn't appreciating the LVM on sda6

You have to add support for lvm in grub

It boots from Grub but only in Emergency Mode/Konsole mode only. I am only able to view logs all cmd's that I try do not work and kick back cmd not found.

I am going to have to enter rescue mode and recovery CentOS later.

I was using this distribution to complete the exercises in the "Practical Guide To Fedora and RHEL and run things in the RHEL Exam Guide. I'm not at all pleased and have to take and break and come back and tend to it this evening.

Thanks for the instruction for upload an image.

I tried booting the Live CentOS CD 3 times to get the boot prompt so I could type "linux rescue"
The prompt flash one time and it wasn't enough time for me to be able to type the letter L.

I did a fresh installation allowing CentOS to take up the entire 500 HDD and all is well now.

It's still not clear what hosed my Network MGR and than made the os go into Emergency Mode but I think it has something to do with Grub taking over the bootloader.
Might even be something proprietary with this Vaio's mobo because Windows 7 used to be installed.
