I Installed GNU Radio live on a usb stick and I was changing some
aspects of its configuration.

​What are you using to create the USB drive?​

I know hot to fix a normal grub2 installation, but as it is a grub2 on a
casper filesystem I don't know how to fix it.  Any help please?

​I expect you'll find it easiest to start over from scratch.

For reference, when we create the live USB drives for our classes​, we use Unetbootin, then replace the installed syslinux and grub configuration files with these:

https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/syslinux.cfg

https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/grub.cfg

These have the extraneous menu options removed and allow the user to choose between persistent and non-persistent modes.  The syslinux.cfg controls the boot options when booting in legacy BIOS mode, and the grub.cfg controls the boot options in UEFI boot mode.
