I used the very same amd64-netinst.iso dated 6 August 2008 to install on a newly built desktop computer, just a straight-forward install with Desktop and Standard tasks. Towards the end the installer installed "grub"... the old Grub (as I could verify after the successful reboot).
Emboldened by this result, I popped the install CD back into the MacBook Pro and proceeded to do a similar installation, using root/swap partitions from a previous installation of Ubuntu 8.04 Hardy (uses the old Grub). I even left off the Laptop task, but again towards the end the installer installed "grub2"(the dummy package) and "grub-pc"... the new Grub. Apparently, the Debian Installer picks up on the fact that this is a dual-boot installation next to Mac OS X, so there is a GUID partition table. The installer is (apparently) configured to install the new Grub in that case, since it can deal with GPT (from the description in Aptitude). Unfortunately, this does not work: without resynching the GPT and the MBR partition table there is "no bootable device", and with resynching (I'm using the Partition tool in the rEFIt boot manager) it gives the error reported earlier. I believe this bug would solved by the Debian Installer giving a choice between installing old or new Grub. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
