The Fast Way to Become a Graphic Designer or Fashion Designer
Hello.
option 1: make sure your guides are on a separate layer, and lock all other layers. Make sure that under View-Guides in the top menu, the Unlock Guides option is on. Select all (command/control A) to select all guides, copy them (command/control C), then open a new document and paste the guides (command/control V, or command/control F to paste in front).
option 2: perform a "save as" of your original document with the guides and rename it a new name, so you have the same exact guides as the first document on the second one you create.
