Please don't panic. It's unlikely that you've lost anything. It's probably very simple to resolve.
SUGGESTION:
1. You definitely want grub.
2. The only issue is to (re)configure grub so that it finds your Windows partition and can boot from it.
GAMEPLAN:
1. Look here:

<= This is good background, but unfortunately we're past that point now
You might want to go back and install EasyBCD after everything's working again, though!

<= Less info ... but more applicable to your immediate problem
2. Boot to Linux.
Post the output of these commands:
Quote:
su - root
mount
fdisk -l /dev/sda
fdisk -l /dev/sdb
cat /boot/grub/grub.conf
|
3. Once we know exactly what disk Windows is on, it should be as simple as editing "grub.conf" and rebooting.
