Begin...! It has always been on, its a contineous process, it doesnt realy stops or begins but just recycles; From, magma - igneous rocks - weathering - erosion - transportation - deposition - accumulation - stratification - cementation - lithification - sedimentary rocks - heating - pressure - stress - deformation - metamorphism - metamorphic rocks - melting - recrystalization - magma, back to igneous rocks. And on and on it goes, repeating just the same process over and over again.
at the beginning of time (see rock cycle) http://en.wikipedia.org/wiki/Rock_cycle
The rock cycle does not have a specific starting point; rather, it is a continuous process that involves the transformation of rock types—igneous, sedimentary, and metamorphic—through various geological processes. For instance, igneous rock can be weathered and eroded to form sedimentary rock, while sedimentary rock can be subjected to heat and pressure to become metamorphic rock. This cycle can also begin with any rock type undergoing changes, highlighting its dynamic and interconnected nature.
The rock cycle has to start at least with igneous rocks, some of which will be eruptive. We may assume that any 'sedimentary' rocks that arrived as meteors have all been metamorphosed, though there are counter instances. For example the Sudbury Meteor and mineral complex. (Canada).
ANSWER: rock cycle
An example that is not part of the rock cycle would be a volcanic eruption, where molten rock (magma) is expelled from Earth's interior onto its surface. This event is a singular occurrence and does not illustrate the continuous processes of rock formation, transformation, and recycling that make up the rock cycle.
The rock cycle can begin with the formation of magma from the melting of existing rocks in the Earth's mantle. It ends when rocks are weathered and eroded into sediment, which can then be compacted and cemented together to form new sedimentary rocks, completing the cycle.
The process by which an igneous rock changes to a sedimentary rock in the rock cycle begins with weathering and erosion of the igneous rock, breaking it down into sediments. These sediments are then transported and deposited, where they are compacted and cemented together to form a sedimentary rock over time.

No, the rock cycle does not have to start from the sedimentary rock
It is called the Rock Cycle.
The rock cycle and water cycle both are natural.
The rock cycle has to start at least with igneous rocks, some of which will be eruptive. We may assume that any 'sedimentary' rocks that arrived as meteors have all been metamorphosed, though there are counter instances. For example the Sudbury Meteor and mineral complex. (Canada).
ANSWER: rock cycle
The Rock Cycle contributes to the formation of rocks : ~ )
there is no beginning or end of the rock cycle
No Rock Comes First... its a cycle
