Dual Boot with Windows 7 & Mountain Lion

[RehabMan]

Would it matter with port the windows drive is in?

I currently have Mountain Lion drive in SATA Port 0 and Windows Drive in SATA Port 1.

I have tried your suggestions without luck.

I don't think it matters. Did you dump your boot record and look at it?
Also, check your BIOS rev. When was the last time you updated the BIOS?

I don't have the latest BIOS (v156) update but I am going to install the latest update now v160.


How do I go about doing a MBR record dump?

<b>Edit #1<b>

x86 boot sector; partition 1: ID=0x7, active, starthead 32, startsector 2048, 716800 sectors; partition 2: ID=0x7, starthead 190, startsector 718848, 976052224 sectors, code offset 0x31

partition 1 = System Reserve
partiton 2 = Windows OS

I think that's what your looking for but I don't know what it means.

My boot disk is /dev/disk0 (you should verify yours w/ diskutil). You do something like this in Terminal:

localhost:trackpad.git Admin$ sudo dd if=/dev/disk0 of=/tmp/br.bin bs=512 count=1

That looks fine. Now you should verify that you have an "active" partition and that it is pure MBR partition scheme. Best place to do that is in Linux gdisk, because it allows you to look at both MBR and GPT, if they exist (you want the GPT to not exist).

I just put Win7 on my machine and had the same issue. I have Win7 on it's own drive, OSX on a SSD and a 1T HD for data.

I also unplugged my OSX drives to install Win7. When I plugged everything back in, default startup drive was Win7. I went into the bios selected the SSD as the primary startup.... Still went to Win7.... Then I unplugged the Win7 drive, made sure bios pointed to the SSD and started into OSX. Shut down, plug in Win7 drive, OSX remained primary startup drive!!!

A bit labor-intensive, but it worked for me....

One thing I remember about the BIOS setup on these boards is that the priority-selection thing is kind of quirky. You have to do something not-so-obvious after selecting your primary drive and I can't remember what it was and don't have the machine handy right now. Something not so intuitive about that BIOS user interface... I remember thinking I had changed the priority selection and then noticing that it didn't take.

Hope those clues help...

The issue is the stage0 boot record, which must be Chimera's (boot0md) and must be on the disk device your BIOS is booting to. You could install boot0md to the disk that has Win/Ubuntu on it, but you'd have to do so manually (using fdisk440):

# substitute your BIOS boot drive for rdisk0 as necessary
/usr/sbin/fdisk440 -f /usr/standalone/i386/boot0md -u -y /dev/rdisk0

I installed Windows 7 and Mountain Lion in same hard drive successfully but when I boot, I don't get the Chameleon Bootloader option. Every time I restart the system it starts up on Windows. Is there any solution like RehabMan mention above? Thanks.

You should make sure your Mac partition is active as this might help.

Install Chimera bootloader again, either from the standalone installer of from MultiBeast.
