It was not in the installation options... Moreover, once I installed Nokia Suite in English(UK), it updated the software in my phone (701), which became English too and lost all support for Greek language.
Yes it is true that Nokia Suite do not have an option for Greek language. But it is very strange that when you updated your phone software it changed your phone language as well.
However, you can choose Greek language in your phone by going to Settings -> Phone -> Language and then you can choose Greek language.
Hope it helps.

Unfortunately ,after the update the settings does not have option for greek language..It is set to automatic and text messages to english...I cannot select greek language anywhere
After an update, your Nokia device may restart in its native language. To change the language go to Settings > Phone > General > Phone language.
If your Nokia device was originally manufactured for use in another country or region, using Nokia Software Updater may revert the set of available device languages to the original language set.
If your preferred language is no longer available after using Nokia Software Updater, you may need to return your Nokia device to a Nokia Care point to have this language reinstated.
