/dev/sda6 Is my Ubuntu
/dev/sda7 swap partition

I have no idea what /dev/sda5,/dev/sda4/and /dev/sd3 are.

The size of /dev/sda4 is clearly wrong

found that I had free space on my computer so I increased my swap partition using Gparted from about 1 gig to about 6gigs.

Now on boot up I get whole lot of text like you do when you use the recovery boot up, which did not happen before.

Available Swap ........ fail (in red letters).

Tried

https://help.ubuntu.com/community/SwapFaq

sudo swapoff -a
sudo /sbin/mkswap /dev/sda7
sudo swapon -a

It did not work.
Bellow are the out puts of

rob@rob-laptop:~$ sudo fdisk -l

Thank you for your help

An entry for one of the swap partitions is wrong in /etc/fstab (first entry). You need to change the UUID to the new one (for /dev/sda7).

Everything looks normal, sda4 is an extended partition (extended=logical and not to be confused with the Second Extended file system, they are different things) the size of /dev/sda4 is exactly what it should be (the sum of all partitions that were created within it)

There are several ways to fix this, the easiest is to edit fstab and reboot.
For swap to work, your fstab should look like this (comment out the uuid stuff):

proc /proc proc defaults 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/sda6 / ext3 relatime,errors=remount-ro 0 1
/dev/sda7 none swap sw 0 0

otherwise, major file system surgery is needed to rectify this mess. If this is a new, un-upgraded install, I would suggest re-installing but taking extra care in partitioning. (with 4GB RAM, you do not need all that swap)

Well I replaced it, rebooted, but it did not make any difference. Did I do something wrong? Thanks anyway.

:lolflag: We have a winner :lolflag:

Problem is solved

Out of interest where did I go wrong???
