can't reinstall windows 7

[zenag]

hi there
hope that anyone can help me!!!
i have windows 7 ultimate installed on my laptop. somehow the drive c containing the windows got full. i tried restarting the computer but it didn't and the start-up repair did his work but when i'm back in windows nothing was the same and windows couldn't launch many applications.
i decided to upgrade it but it kept telling me there's not enough space i deleted everything i have about 33 Gb free on the C.
i tried to reinstall it but when i reach the place where i should choose which drive to format i can't see neither the drive C nor the D that contains only data.
by the way when i open control panel it's empty so i had to erase the programs rather uninstalling them.
Help please if anyone know anything about it i'll be very thankful

Unplug other drives, Boot Win7 DVD, press Shift F10 to open a Command line, type:

DISKPART
LIST DISK
SELECT DISK # (for Windows 7 HD)
clean
create partition primary
select partition 1
assign letter=c:
active
format
exit

Now install Win7 doing a Custom install from booted DVD.

Suggest that you monthly clean and order your HD using free state-of-the-art CCleaner "Run Cleaner" and Registry tab, then the Auslogics Disk and Registry defraggers.

Bring these issues to the forums in the future so you can avoid messing up your OS. After you have it up and running as you want, save a Win7 backup image externally so you never have to reinstall again - just reimage the HD using stored image and DVD or Repair CD.
