by "disk drive" are you referring to an optical drive, like DVD? If so, you would need a bootable USB device.
GParted is an excellent partition program.
pay heed to the warnings.
Recently my computer gained a virus so I decided to format my HDD. How ever, I couldn't get passed the dreaded ""We couldn’t Create a new partition or locate an existing one." screen.
I did everything on this site http://www.partition-tool.com/resource/manage-partition/we-could-not-create-a-new-partition-or-locate-an-existing-one.html
Which includes re-plugging my usb boot and running Diskpart. But I still cant get it to start. Please help me ?!
Added stuff: I dont have a disk drive and the only option is usb.
