re-installing windows vista

[raitoyagami]

what happens if i re-install windows vista, i was told its like reformating but i dont know what will actually happen and i was also wondering how do i use vistas repair thing form the CDs that it came with cause i was told that it should have the opions of reformating and repairing when i run the CD but all it says is if i want to re-install it.

set the pc to boot from the cd/dvd drive first, then hit F8 to get to the advanced start options...
