Friend, if you (read as installer) deleted partition you don’t have hope until and unless you use something special software available on net. Here is google search for you:

Now to uninstall Linux (wonders why you want to do that)!
1) Boot from Windows 9x / DOS cd / floopy
2) Run fdisk and rmove NON-DOS Partitions
3) Run (to restore DOS/Win MBR)
fdisk /mbr
4) Reboot System
5) Proceed with windowz installation
