I asked the gparted maintainers towork out a way to comvert MBR to GPT and preserve the patitions and patition table. They said that ever OS has a different boot program, which they probably couldn't recover. I told them that that would at least me to run a rescue disk and re-run grub=update. This would be much faster than the dance I had to do. Maybe they'll do it. > > > David >
