Thx for your reply again
What I mean is that when I bought the laptop, there was just a single Hard disk plus the recovery partition on its own. I divided the hard disk into two partitions C and E (and F contains RECOVERY); C contains the windows.
My question is what is better solution:
1- save all my data on external hard disk and use the Recovery, after that divide the hard disk again into two partitions
OR
2- only format the primary hard disk which contains the windows. But I need the drivers so I use a software to extract all drives on the laptop to use them in the formatting because no driver CD came with the laptop.
Thanks for help
