EU ministers say Greece will not get funds from the second EU/IMF bailout until its private creditors give final approval for their losses next week.
Eurogroup chief Jean-Claude Juncker said on Friday that Greece had taken all the legal action necessary to get the 130 billion euro ($US175 billion) bailout.
But he said the bailout must await the debt swap with private bondholders on 8 March.
Private bondholders, such as banks and private investors, recently agreed to take a 53.5% loss on their Greek bonds. The BBC reports their losses amount to 107 billion euro.
This "haircut" and a huge package of public sector cuts aim to reduce Greek debt from 160% to 120.5% GDP by 2020.
Earlier Greek MPs backed the last major package of reforms promised in return for the second bailout.
A series of health budget cuts were confirmed despite protests outside parliament in Athens.
