Hi there,
You need to move that little partition to the end of the disk first (use a third party software for this), and then you can expand the main partition.
Hope that it helped you.
Best regards.
Hi @abakisensoy,It's a rescue partition 523MB . Which program do you reccomend_?
I just did this today completely in Windows (with just MS tools already installed). Just google for "remove recovery partition" in you language, its easy and you don't normally need a recovery partion in a virtualized environment.
