Wiped hard drive "clean" no partitions by mistake need help

[obupiperb]

wiped entire hard drive clean 750GB, nothing on hdd, no windows 7 operating system.......help
System

Dell Inspiron 1545, 4 gb ram,  64 bit system, naturally no windows 7 install disks, it was on the drive , exchanged my clean hdd with another hdd, 320gb, same computer, works fine with this hdd.

I have tried to make a recovery disk from the 329gb hdd to use on the 750gb but there is no windows operating system.  Looked on the Dell support site for a purchase of the install disks but not found.  Is there any solution to complete a reinstall?

I have a Vista operating system install disk and tried to install this to get some partitions.  System installs but no boot only Microsoft sliding bar appears but is moving.   the Vista is only 32bit, i'm sure the 64 bit conflicts.

Any resolution to this problem....I would to use the 750gb hard drive but there is no operating system.

Thanks for the  help.

Let's start with this. EXACTLY what did you do?

Using Spotmau 2011 Bootsuite Gold I formatted the entire hard drive.   When the warning indicated the entire hard drive would be wiped clean I failed to understand the Data Safe portion would be too.

testdisk (on the Parted Magic distribution, amongst others) can find and  recover deleted partitions under certain circumstances.  Might be worth a shot.
