Follow these instructions, everything will be wiped and you will have a clean (the best) install.

Thank you sir ... what about if first need to remove/delete up everything and then will decide to install 7 or XP ?

Do any software or manual way to remove/delete and ensure system is empty 100% from old O/S and other DATA/files e.t.s ?

Appreciate your help

Thanks - Hani

What type of DVD are you using to install; upgrade or full retail?

am currently not installing anything

I just need to know how i can ensure everything in system gone away ... deleted/removed!

Tks sir ....

I use partition wizard to delete all data. Boot from a OS installer. YMMV.

Gents,
What about if i use Partitions Wizard and delete or format C drive .... which holding the Windows O/S .. is that the right way to format and ensure all DATA removed and the i can install the Windows from the beginning?

Do i will be able to run the CD after doing this?

Tks alot

Yes I believe you will. If you have a bootable cd such as a windows 7 install dvd

You need the Partition Wizard bootable CD, choose Wipe Disk and apply as many sets of zeroes as you can stand - each set will take about an hour on average size HD.

You can do the same thing by booting your Windows 7 DVD Repair console or Repair CD, clicking through to Recovery Tools list to open a Command Line, type:

DISKPART
LIST DISK
SELECT DISK # (for Windows 7 disk)
clean all (applies one set of zeroes, takes awhile - to do it quicker remove "all")
create partition primary
select partition 1
assign letter=c:
active
format
exit

You are now ready to Custom clean install without needing to format first.
