Hello, i've tried this once, and it worked. But the tradeoff was, that i wasn't able to boot into the Windows installation via paralles. So i changed it back. If you don't use parallels workstation for booting your windows installation under MacOS then just go ahead.
First you have to get the MBR right. This is easily done via fdisk under linux. The problem is, that this will break you GPT. The best way to fix this is to correct it by hand with the MacOS Boot CD, a console and the "gpt" command. Try man gpt for usage instructions. For doing this you first have to know the sectors where your patitions start and end. You can get these with fdisk under MacOS. Type in the console: fdisk -e /dev/rdisk0 and then enter 'p' for print. This will show you the MBR-Table with the numbers you need to edit the GPT. with these numbers you edit your GPT. First flush the GPT. gpt destroy /dev/disk0 gpt create /dev/disk0 Now you have a empty GPT. The first entry is created via: gpt add -b <start-sector> -i 1 -s <size_of_partition_in_sectors> -t efi /dev/disk0 The the other entries are created as described. Just change the 'efi' part to 'hfs' for the MacOS partition, 'windows' for the NTFS partition and 'linux' for the ext2/3 partition and increase the '-i 1' to '-i 2', 3 and so on. As it specifies the slot in the gpt where the entry is created. When you're done you should check via gpt show /dev/disk0 Don't be worried about the same GUID for Windows and Linux partitions. That is OK. Referring to http://en.wikipedia.org/wiki/ GUID_Partition_Table#Partition_type_GUIDs do windows and linux use the same GUID-Type. (that's why it's called "globally unique" ;) i don't know why!!!) Good luck. And don't forget to do a backup of you data ;) Messing around with MBR and GPT is quite dangerous ;) After all. You should be able to see your ext2 partition under MacOS :) cya, Sebastian Steinmetz Am 21.02.2007 um 12:48 schrieb Sven Anders: > Hello! > > I'm using rEFIt to dual (triple) boot MacOS and Linux. > Now I want to use the MacOS ext2 filesystem driver, but it does not > recognize > my Linux partition.
