Another affected used. Syncing partition tables with a refit rescue cd was able to rectify the problem. It occurred for me when I tried to install grub to /dev/sda and to (hd0).
-- Partition Table is cleared during install on Intel Macs https://bugs.launchpad.net/bugs/222126 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. Status in grub-installer: New Status in Mactel Support: Confirmed Status in “parted” source package in Ubuntu: Confirmed Status in “ubiquity” source package in Ubuntu: Confirmed Bug description: Binary package hint: ubiquity Ubuntu 8.04 Final Intel Macs have an EFI system and a GPT. The installer seems to handle the GPT correctly (as it has in the past), but it has recently come up that the installer is completely emptying the contents of the MBR partition table which is still required to boot Windows and Ubuntu (GRUB relies on the MBR partition table). The two tables are not synced automatically. When users install Hardy, they are suprised to find that the system is unbootable (the EFI loader cannot "see" the partition as bootable). a tool such as rEFIt or gptsync can copy the information in the GPT into the MBR table thus fixing the issue (for most). This is even more serious for users with other working OS installs in addition to Ubuntu (such as other linux distros and Windows) since it completely dumps the information needed to boot these installs as well. The expected procedure (and how the previous Ubuntu install seems to have handled it) is to 'update' both the GPT and the MBR table with changes instead of completely losing the information stored there. gparted / parted seemed to update both tables properly previously as well. I will be doing a full install on my iMac later and will be able to add additional information. _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
