There is no bulk edit rom path feature in Launchbox yet though it is something I have been asking Jason for a while.
The easiest ways right now is to either remove your games from LB and re-import them or use a text editor like Notepad++ to "find and replace" the path in the platform.xml, this is the way I did it when I moved my roms before.
If you do the re-import you can turn off the data and image scraping in the import wizard to speed it up.
Thanks, that worked, I formatted my PC and it changed my drives letters and this solved it .
