I mentioned my new SSD drive elsewhere and got good, if somewhat conflicting, advice.
Basically I've installed two new drives, an SSD and a HDD while keeping the original HDD which had three partitions.
I'll add a screenshot.
I neglected to back up my FireFox bookmarks and thought they were lost even though I suspected they may be hidden somewhere in the old HDD drive.
This morning, much to my surprise the PC opened in/from the old drive so, regardless of anything else I immediately backed up the bookmarks.
I then rebooted and the PC started normally from the SSD drive.
I now have a back up of the bookmarks but don't know how to reinstall them, it mumbles something about syncing.
I don't know how to deliberately start the PC from the old drive either. (Windows 7)
Does that make sense?
I cannot see how to add a thumbnail here so will have to drag and drop a very large image. Sorry about that.
OK, it wont allow the image, you'll have to use your imaginations.
