imac 23inch with nvidia 2009 era

Hi All
trying to help a friend who had an issue after mageia 5 upgraded with a black screen.
hes now installed mageia 6.0 x86_64 classic iso on the second partition, with macosx on the first.
he does not use macosx any more as its way out of date.
mageia 6 installs OK but at the very end says the following

canot find a grub drive for /dev/sdb

then it says

This GBT partition label contains no bios boot partition .... and some thing else

anyone recognize this error, or has tried this on any apple based system.

looks like the system is booted by legacy bios but has a GPT HDD.
You / he will need to make a small ~50MB partition and flag it as bios boot, it does not have a mount point. it does not need to be at the start of the drive.
this can be done by the installer - custom disk partitioning, under advanced : create the partition and choose "type: boot bios". there is no mount point needed to be applied.
you do not need to re-install the entire system, so no need to reformat the / and or /home partitions. (so a dirty re-install, takes about 5 minutes)

cheers
