First, thanks for the 43 release, my first upgrade seems to have gone flawlessly.. My first bare-metal install has gone just like a previous 42 install. The situation is * Everything is a RAID1 mirror. There's about 25 GB of system filesystem and 130 GB of home space. * The installation goes flawlessly and takes ~10 minutes. * On reboot grub just isn't there. There's no attempt to boot off any disk. * Booting off a rescue disk and running grub: root (hd0,0) setup (hd0) fixes everything. Has anybody else seen this? My working hypothesis is that the RAID arrays hadn't finished syncing. Thanks John
