recover lost partition > undetected (not unallocated!)

[firuzzz]

I just re-installed my pc with Windows10 (from a W7 upgrated to W10), it started working really bad so.
I put the DVD and reinstalled, but when the installation finished I realized that my "D:" drive wasn't there anymore, just C:, and Windows.old folder is empty!. so I literally lost everything.
Most problems of "losing partitions" shows an unallocated part of the disk that can be recovered by a software, I don't have this unallocated sector, just a SSD (originally of 250Gb) with a C: drive of 149Gb AND the D: of 100Gb is gone.
Any suggestion, I couldn't find anyone else with the same problem.
Plus: the others 2 HD of 500GB (not SSD) each are not detected neither, but those 2 were empty, I don't really care about them now

Have you looked at the Disk Management part of the Control Panel's Administrative Tools applet? That's usually able to show all partitions and allow you to assign a drive letter to any that don't have one.

Good luck.

After a few resets and installed a chipset driver of the mobo, the partitions appeared, with E and F letters, I moved the letters to D and E .. and everything worked since then
