I just decided to install Ubuntu 12.04 alongside Windows 7 on my Dell laptop. However I didn't do this manually but instead used the "Install Ubuntu alongside Windows 7" option during the installation. Now the partition that Ubuntu runs in has very little space and I am getting warning messages.
I'm trying to use
gparted 0.12.1-5 (via a live CD) to give Windows less space and give Ubuntu more. I've managed to remove 100GB from the Windows partition so I now have some unallocated space between Windows and Ubuntu.
This is what it looks like inside Ubuntu (not using the live CD, since it won't let me mount a USB to save a screenshot):
So first I take
sda4 (extended?) and resize it to the left so it takes up all the unallocated space. Then I resize
sda5 (ext4) as well so it takes up all the new space.
However, when I hit apply, it fails on the first action (resizing
sd4) with the error message
can't have overlapping partitions.
Any ideas as to why this happens? I also tried resizing
sda4 by just a few MB so that it definitely didn't overlap anything, but I still got the same error message.
To clarify, I am using
gparted from the LiveCD, I just took the screenshot from Ubuntu.
I couldn't attach the details file containing the error information from
gparted because I can't mount a USB drive when I'm running from the LiveCD.
I'm tried following the guide on the
gparted website but it says
Invalid argument or something like that. If the
gparted details are needed, I may need some hints on how to solve the USB issue as well. :)
