GotoXX seems to be hit and miss, although ive never had a problem with it, alot of people on here have reported difficulty in getting it working.
also if your going to multiboot and try a few images, make sure the
smartsettings copy from active image is ticked, then the settings and channels you have working with one image will be copied to the new one
FWP can save your settings mate
get it so your happy then save the settings.
then in the
install new firmware button (top left) choose the big button in the middle
flash image backup
if all goes pear shaped after that, flash erase and use FWP to reload it
