Inspiron M5040 running Win 7 Home Premium and I downloaded Windows 10 tech preview. My computer is now very unstable and my printer driver doesnt work so I tried to "roll back" my OS back to Win 7 but this doesnt work either. I have a new Win 7 installation disc but I need to format the entire HDD to get everything off of it and start over. Does ayone know how to FDISK this computer?
MIcrosoft Windows 7 Home Premium SP1 X64
AMD E-450 APU w/Radeon HD graphics, 1650 Mhz, 2 Core
SM BIOS 2.6
RAM 4 GB
Thanks
