When installing BootHDR on a HD-FOX, the installation appears to hang. If you cancel, eventually you get a another dialogue box pop up. Click OK to close this. The installation does work. To remove, on a HD-FOX, uninstall as standard through package management. The initial installation creates the folder HDRfs (and its contents) in the /mod folder: this is not deleted when the package is removed. I delete this folder, using Web-If, to finish off the uninstall. I don't know what happens on a HDR-FOX as you will already have a HDRfs folder. On the HD-FOX, these files are installed on /drive1. If you had USB drive attached when you installed did it create the HDRfs folder on the external drive?
