I'm just wondering out loud here.. When linux loads it creats a boot partition, very small, to load Lilo or Grub, the linux boot loaders, i'm wondering if you deleted this partition? Maybe its still there, and windows can't boot because the Boot loader is still trying to bring your machine up?
Check it out, but booting of a floppy with Fdisk, and see if there are any strange partitions
Alternativly, repartition the Harddisk again, but this time, use the recovery tools from the Suse Boot disk...
As sometimes FDISK windows doesn't recognise the linux partitons..
