misaligned partition

Asked by Gabor Vas on 2011-06-17

After several installation process (of Debian 6.0 and ubuntu 11.04 Natty) I still have a strange problem: partition 4 is misaligned, although it doesn't really exists as you will see in the end from fdisk -l. Disk utility and sudo parted reported the problem. What shall i do? Get a boot CD with gparted and then?
During the installation processes it never wanted to create a sda4 it always went for 5...
The system is a new acer aspire 5750 laptop, 4GB RAM, Core i3 ant yes, a 320 GB HDD.

Thanks very much in advance
