When booting VyOS 1.2.x development ISO there are non functioning boot targets in the GRUB configuration. This was very confusing to me when switching to VyOS 1.2.x
- Install (nothing happens)
- Graphical Install (nothing happens)
- Advanced option
- HDT (file not found error)
- memtest86+ (nothing happens)
My suggestion is to remove all nun functioning targets. One could say that memtest and HDT would be nice but a user could easily boot a Debian installation CD, too.
