Windows 10: How to recover data after reinstall the windows

I reinstalled my windows today so stupid! and lost all my data. The weird thing is that after I installed the windows, the data was still in the windows.old folder. But all data and files in the folder was gone on the second day I didn't restart it before I made a copy. Does anyone have any ideas to recover the data? Thanks!

Windows 10 won't boot, repair, recover or reinstall

Thank you, Gerard! I appreciate your help.

I tried using Win 10 boot media to reinstall from scratch. Install chugs away for a while then shows me a list of partitions on my hard drive. No matter which I select, Windows can't be installed because they're GPT partitions.

I've also tried running chkdsk /r /x as suggested in another post. That seemed to run without any problems, but when I restarted I eventually got a blue screen with error 0xC0000021a.

At this point it's looking like I need to completely reformat the disk and reinstall Windows from the boot media. Is that the next step? I've recovered my data - which is all still accessible.
