Was running lightroom on one installation of Windows. Then I decided to move to an SSD so I copied over the catalog with the Adobe lightroom folder that resided in c:\users\username\pictures\adobe lightroom (I think that's the path).
Abyhow, this worked great. Then one day I accidentally did a project in my old installation of Windows (old catalog) and booted back to my SSD. The catch is that I deleted the windows install off that drive afterward so I can't boot it anymore.
Currently I have a batch of edits that do not exist on my SSD installation.
Is there any way to import from the old catalog? I didn't delete my Adobe data off the old drive, just the windows folder.
To retain your development edits, keywords, flags, etc, you will need to "Import from a Catalog"
Read the paragraphs- "Import photos from a different Lightroom catalog" at-
A similar situation in this video-
And- "To combine or merge catalogs — or to move photos from one catalog to another"
