prepare a hdd for new OS - best method

[Rytron]

Hi,
I am going to remove my current OS on my old PC.
I used this method before:
I booted the old PC from Hirens cd. Then I used one of their partition managers to delete the partition. It then said the whole hdd was unformatted. Then I installed a new OS.

Is this the best method or can this lead to errors on the hdd?

That method will not damage the hard drive. It should work fine.
