This question already has an answer here:
So I have an old windows vista laptop on which I decided to try ubuntu.
I thought I had got it right, but the windows OS is still there. I know it works alright as it is, but I'd like a fresh start with my pc, without the windows part. There is only one HDD in this computer, with both Ubuntu and windows. i noticed that after I installed Ubuntu, my HDD seemed to have split into two partitions (is this of any point?)
I wonder if I just format the HDD will i loose my Ubuntu installation? will it not be able to complete? will it not format the partitions?
Should I just format the entire pc using a bootable usb-stick and then install Ubuntu likewise? if that's the case, is there an ISO file somewhere that will do both or will i have to do this in two separated actions? like ... first making a bootable usb for formatting, and then making an other one to install Ubuntu (again)?
i have to problem to lose everything that's on the hdd whatsoever. I just need a fresh hdd with ubuntu, and the easiest way to do it?
