Did a cockup on my garage PC after installing a SSD in it.

Basically had cloned the partition off a 1TB drive onto the SSD, had it all booting and working, deleted that partition from the 1tb, expanded the second partition to take up the whole drive (it took ages so would have overwritten the 115 gig partition moving the stuff over it - so wont be recoverable off that)

Anyway, the SSD was working and I used it for a few days, then needed to clone a laptop HDD to another SSD that was exactly the same. No worries, will use the garage PC.

Anyway, I ended up puttign the 100 meg patition over the start of the system SSD in the garage PC before noticing I still have it plugged in and there were 2 SSDs plugged in and I had chosen the wrong one.

All the stuff is backed up as it should be, but if I can get the install back (even if its just to the point that I have to boot windows 7 installer and do an over the top install) it would save me from installing a hell of a lot of esoteric stuff that I have probably forgotten about.

So far I have tried easus and one called Active@ partition recovery, but they are just finding lots of weird boot and system reserved partitions, not the old OS partition at all so I am guessing that something to ID the partition has been overwritten, and trying to get files back in easus lists a whole lot of weird things.

Other tools to try before I throw in the towel and either restore a really old system image or just do a new install and restore all my stuff from crashplan?
