OMNIDISKSWEEPER WINDOWS DRIVER

boot MBP with GParted Live CD (version 0.3.7-7 works ok, version 0.4.1-2 has problem with screen resolution which must be fixed by manual configuration: resolution 1024x768, driver VESA).

Don't worry about the windows partition size, we will delete it later

use BootCamp to resize MacOSX partition to 40G.

OMNIDISKSWEEPER WINDOWS INSTALL

start MacOSX, download and install rEFIT from.

But it's still the best choice for sharing data between MacOSX and Linux. Ironically, we cannot access this partition from WinXP, since Windows uses MBR partition table and hence cannot see this share partition. NTFS can be accessed from Windows, MacOSX and Linux so it's a good choice for data that are likely to be shared between systems, like photos, audio, video, iso images, downloaded programs, etc. GParted can grow/shrink/move NTFS without problem. To expand /home partition, use GParted Live CD to shrink the share partition (below) and then expand /home. jfs cannot shrink so it's better to start small, and expand it as needed. home partition that is shared between linux systems. It's handy to have an extra partition to install another linux system for testing purpose, so that we can test another linux distro (for example a new version of Ubuntu) without re-partitioning. Primary linux system, at the moment Ubuntu-8.10 Swap is used for linux, and must be as large as RAM amount for use with suspend This partition can be accessed from both linux & OSX, so it's not harmful to give it some more space than needed.

OMNIDISKSWEEPER WINDOWS SOFTWARE

I use WinXP from time to time to run or test software that don't run on other OSes. Then we boot linux from grub just like on PC. Grub must be installed to this partition (right after the MacOSX partition) so that rEFIT can chainload it. MacOSX can access NTFS, so non-system data (like audio, movies, etc.) can be put on another NTFS partition. It's good to keep the MacOSX partition not too big so that I can backup the whole partition to an external USB disk (mine is 30G). I don't use MacOSX very often, so I don't need too much disk space for it. I made some notes on my partitioning scheme: MBP comes with preinstalled OSX on the whole disk.

linux partitions can be as many as we wish.

If Windows partition is not in this position, installation goes ok but then it cannot boot (mystery error with missing hal.dll)

a small ext2/ext3 partition to install grub.

the order how the OSes are installed is critical:.

It's fairly easy and safe to change the partition table (including grow/shrink partitions) this way if we follow strictly this practice: whenever we change the partition table with GParted, always use rEFIT to sync MBR table from GPT. Linux & MacOSX don't look at MBR partition table (they use the GPT one). MBR partition table is needed to boot MBP in BIOS mode and is used by Windows. It's OK that after syncing, the MBR partition table looks different from the GPT table.

to change the partition table, use GParted Live CD to boot MBP and make desired changes, then use refit to sync the MBR partition table.

The best tool to deal with hybrid partition table MBR/GPT is rEFIT.

hybrid partition table MBR/GPT and BIOS is required to boot Windows, and also Linux if we want graphics acceleration.

I find it important to know these points: I don't use MacOSX and Windows very often, but I find it useful to have them installed, they can be very handy to run some applications (Google Sketchup or 12VoIP are good examples).Īfter many trials and errors, and spending quite some time googling, I found Also, it is not true that when we use Linux/Windows on MBP, we are limited to 3 usable partitions, as often stated in many guides about dual or triple boot on Mac. It is possible to have on MPB MacOSX, Windows and a few linux distros.
