sizing impossible to the main partition of Ubuntu

Thanks
I will move the partition on the left and then reboot my computer to see if Ubuntu starts again.
In case I have my Windows 7 operating system for the moment, waiting that I install Ubuntu, and yes I will save all my data.
I will do that on the afternoon

Great.
As advised by grahammechanical, do the GParted operations one by one. First move sda4 and apply the change with the green button. Then extend sda3 and apply the change and then resize sda6 if needed.
It may take some time to move the 66Gio.

Note: I stand corrected, you've not a MBR boot but an EFI (I mixed the information with another post of the topic). But then, it seems to be more robust. Higher chances that there is nothing to do afterward.

After having moved my two partitions, every thing looks to like to work good.
To expand my /dev/sda6 it takes 30 minutes.
I have also created a live USB of Ubuntu just in case.

Thank you very much all !
