[Solved] Kernel downgrade to 3.10.39-1-lts doesn't show up

I downgraded my kernel from 3.14.1-1-ARCH to 3.10.39-1-lts so as to install Intel VTune.
I did:

sudo pacman -S linux-lts linux-lts-docs linux-lts-headers

then rebooted the system. Upon reboot

$ uname -a
Linux laxmi 3.14.1-1-ARCH #1 SMP PREEMPT Mon Apr 14 20:40:47 CEST 2014 x86_64 GNU/Linux

So it still shows the old kernel.

However, I have /usr/src/linux-3.10.29-1-lts directory and /lib/modules directory shows directories for both
3.14.1-1 and 3.10.39-1.

I searched the wiki and the forums. Have I missed a step in the installation process? This is my first attempt at
changing the kernel on ARCH. I am a bit worried.

You need to make sure you are launching the kernel you want with your bootloader.  Your bootloader may be GRUB, SysLinux, GummiBoot, rEFInd, or other.  Whatever you installed when you set up your Arch system.  Some bootloaders will need their configuration regenerated and will pick up the new kernel which you then choose on boot.  Other bootloaders you will have to edit their configuration files to create an entry for the new kernel.

Whichever bootloader you use, we can't go any further until you say which one it is.

Thank you so much. I use syslinux and was able to make necessary changes.
