Looks like it might be an EFI installation on GPT disk.
Maybe the Linux tool you ran corrupted the data as you suspected, so that it is only showing in Recovery Wizard.
There is a recent thread where a data recovery software was able to recover the data (not partition structure) from a GPT disk. I'll try to find it or maybe someone else will link to it or recall the software.
Do you have your files backed up elsewhere? Because even if you can recover the data it will likely require a Clean Reinstall.
I would convert the HD to MBR to reinstall with EFI taken out of the BIOS boot order
