Boot error when Linux Lite not first (default) choice in grub menu in dual-boot

[hughparker1]

Our distro is aimed at Windows users, so our grub is set up in such a way as to easily identify our OS from grub when they dual boot with Windows.

thanks for quick reply, I appreciate your feedback. 

I have just encountered an unexpected error after I ran sudo apt-get update and wondered if this was related to my previous steps above....

Code:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
hugh@DELL-VOSTRO-LINUX-LITE:~$

so I ran the command suggested...

Code:

$ sudo dpkg --configure -a

Code:

hugh@DELL-VOSTRO-LINUX-LITE:~$ sudo dpkg --configure -a

I notice there are errors above but I'm quite new to linux so don't know how to fix, any help would be appreciated.

I ran sudo apt-get update again and it completed ok

hugh@DELL-VOSTRO-LINUX-LITE:~$

then I ran uname -a

Code:

hugh@DELL-VOSTRO-LINUX-LITE:~$ uname -a
Linux DELL-VOSTRO-LINUX-LITE 4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
hugh@DELL-VOSTRO-LINUX-LITE:~$

So looks like I'm still using older kernel.

Not sure how to fix this as I'm still learning linux
EDIT: When I restarted laptop, I couldn't login, just froze after entering password, cursor not moving. So I decided best to re-install as I didn't have any data that was worth keeping. Hopefully it will go better second time round.
