I've been trying to triple boot my laptop with a single HDD. An Ubuntu+Windows+Chromium OS is what I want. Now, I think my problem is a bit deep and tricky, but I'd really like you guys to help me in anyway you can.

So here it is. I'm having trouble installing Windows to a GPT type partition table, which means I have to stick to the MBR type. Unfortunately, it only allows 4 primary partitions, or 3 primary + 1 extended partition.
I know I can install Ubuntu, as well as Windows to logical partitions. I'm not sure about whether Chrome OS can be run from logical partitions.

My problem would probably be solved if I'm able to run Chrome OS from logical partitions. I'll have to keep 1 primary partition as System Reserved in order for Windows to boot normally. Out of the 2 primary partitions left if I choose this case, both of them will go for Chrome OS if it's not possible to install it to logical partitions. [Chrome OS needs at least 2 partitions to run, at least that's what I found out of my week long research. ]

I read the answer in this post, and I feel it's kinda incomplete. The answerer hasn't addressed the second partition needed by Chromium. Neither has he addressed the swap partition needed by Ubuntu. If this answer is considered, 5 primary partitions would be needed at the least. Which ain't possible with MBR. Can anyone here help me with my problem please? I'd really appreciate your help. :)

  1. Install Windows, which will occupy the first 2 primary partitions, use its Disk Management tool to reduce Windows partition as desired, and create a "Recovery Disk" under Windows.
  2. Boot your computer from live Ubuntu disk, start GParted, delete the "System Reserved" partition and grow the Windows to the right, to take up the empty space left by the "System Reserved" partition.
  3. Restart your computer and if Windows fails to boot, repair using the Windows Recovery Disk. (NB: I tested this successfully with Windows 7 only.)
  4. Boot your computer from live Ubuntu disk again, start GParted, create 2 primary partitions for Chrome OS, and then create a 4th Extended Partition, which may contain, for example, a partition for Ubuntu /root, a partition for /home and a swap partition.
