Deleted the SUSE Linux how?

Do you still get the GRUB screen to let you choose which OS to boot into?

Yeah I used GRUB to select which OS.

I booted into WIN7/disk management and deleted the partitions. Shrunk the volume.

Now I get that black screen with the PXE error.

Yeah ST9500325AS-(S1)

Looks good but of course I don't have a install cd. and procrastinated on making a backup recovery CD.

here's how you restore the boot record:

Is there nothing I can do from my side?

I made a recovery partition on an external hard drive but I don't know how to boot from it? or how to access it. Or should/can I put it on a cd/dvd?

You're not going to be able to do anything without a bootable Windows CD of the same version that's on the drive, no.  You need to write a new bootsector.

You can't boot from a recovery partition.  You need a Windows DVD.
