【Solved】persistence no prompt

[bertus65]

Hello,
I like Ventoy very much, but now I have a problem with persistence.
Now I want to use a live ubuntu20.4desktop with persistence.
What I've done so far: 

• searching on this forum for a solution
  
• ventoy 1.064, tested with uefi and legacy boot
  
• No prompt menu displayed? (prompt for select boot with or without persistence)?
  
• http://json.parser.online.fr OK
  
• During Ventoy Boot pressing <f5> check persistence plugin configuration shows Image=ok, Backend=ok, Dump Persistence=succes
  
• in grub vt_dump_persistence same result as previous step
  
• label persistence file casper-rw (I read in https://askubuntu.com/questions/1297758 since ubuntu version 20 this should be writable,
  but I think this is not causing my problem "no prompt menu" 
  

Can someone help me to fix my problem?
Best Regards Bart
