Windows 7: How do i wipe out everything on my computer and reinstall?

How do i wipe out everything on my computer and reinstall?

I will first list my computer specs.


Asus U45JC Laptop
Windows 7 Home 64 Bit
Intel Core I3 M370 2.4Ghz.


I have the 2 CDs for my Asus Laptop. The Reinstall CD and the CD from Asus to reinstall the programs. I have many times reinstalled my laptop by just installing the CD and following the instructions here

Complete Walk-through For Doing A Clean Windows 7 Install


It works. The problem though is everytime I do this... I still see the old program files that was left on my computer before i reinstalled it. So i basically want to wipe my laptop completely clean... and then install windows 7 again and the programs.


Can someone tell me the easiest way to do this? I have tried previously before but it was very complicated and I couldn't get it to work. I think i followed some instructions from another guy in a forum where the steps were either complicated or one of the steps didn't work for me. I don't recall but it had something to do with the command prompt but i could not get it to work.

I saw this link posted

SSD / HDD : Optimize for Windows Reinstallation


Is this what i should do? Because i tried this many times and it never works when i type CLEAN OR CLEAN ALL... it always say Virtual disk service error: clean is not allowed on the disk containing the current boot.


Does anyone know the reason for this? Okay i think i made the mistake here as its mentioned i have to do this while restarting or starting windows?


So i restart.... then press F8 and i see a screen that shows this

Advanced Boot Options


What am i suppose to click now? I tried the start windows with command prompt in safe mode and still when i type CLEAN OR CLEAN ALL... it still error

Windows 7 Home Premium 32-Bit - Build 7600 SP1
 
 

If you want to start with a clean disk, nothing on it and install Win 7 as a Clean Install, do this. Go to this site Dell Community and download the Win 7 ISO file that fits what you have, Home Premium, Professional or whatever it might be and also 32 or 64 bit. This site says Dell, but it is the same for all. Burn the file onto a DVD at no faster than 4x speed. This will give you a good disk to install Windows 7 from. You can then use your Product Key sticker (25 character) that is on your PC to activate the Win 7 after it is installed. Here is a tutorial to guide you in the installation. Clean Install Windows 7 Let us know how it goes. == Just remember to backup your data, if you don't want to lose it. The Clean Install will wipe your C: drive.

From your first post it sounds like you were running diskpart from inside the windows environment in which case windows will not let you play with a partition it is installed on to do this you need to run from a command prompt before loading windows.
During the clean install process (as above) windows will let you delete/create partitions on your HDD which will blank the disk but this process will not permanently overwrite all data on the drive
If you specifically want to run diskpart to truly erase all data then press shift + F10 when you get to first installer screen when you are installing windows as per bigmck post then when you get to command prompt type
diskpart
list disk
select disk X (where x is the drive you wish to install to)
clean or clean all (depending on which function you are trying to carry out)
create primary partition
format fs=ntfs
active
exit
exit

be aware that doing this will erase everything and is unrecoverable so make sure you get it right, if you do do this you are strongly advised to backup all your data and UNPLUG ALL OTHER DRIVES except the one you want to put windows on
One bonus of doing it this way is that you will not get the small 100MB boot partition that Windows 7 automatically creates when you do a standard install

Everything you need is here to get a perfect Clean Reinstall - Factory OEM Windows 7.

During install use the Custom install Drive Options to delete all partiitions and create new as you wish, install Windows 7 to the first large partition - ignoring the 100mb boot partition it creates.
