Dual Boot - Win7 & OSX

fvs · #1 10-07-2009, 09:37 AM

Hey,

Im trying to create a dual boot with Windows 7 and OSX. I have allready installed Windows 7 and later installed Mac OSX from iAtkos. Installlation of Mac OSX went fine, but when i restart my pc after installation it automatically boots into Windows.

EDIT:

Im able to boot into MacOSX now through EasyBCD. The problem is, MacOSX keeps telling me everytime i boot to restart my pc. Whats wrong?

Thnx in advance,
greets, fvs

it might be you didn't put entry of Mac in EasyBCD.. sometimes it happens due to it.. You will need your Windows 7 Retail DVD & Distro used to install Apple Mac...

Do you have a single drive or two separate HDs?
If after installing iAtkos you dont see the chameleon bootloader it could mean this one didnt get installed correctly, or if you use 2 drives maybe you didnt change the disk boot order in the BIOS.
EasyBCD only chainloads from windows bootmanager to chamaleon, you should be able to see the chameleon menu and boot in verbose mode (-v) to see whats happening in OS X.

Thnx for the replies, im a bit further now. I tried it with a new DVD, from iPC.

When i put my MAC drive as first bootable, i get the message "still waiting for boot device". When i put my WINDOWS drive as first bootable and select to boot Mac OSX, i get the Chain0 error. (I allready copied the Chain0 file to the root of my windows system).

My setup:

CoreI7 920
Gigabyte GA-EX58-UD4P
1HDD = Windows
2HDD = Mac
3HDD = Data

EDIT:

Im able to boot into Mac now and found my problem: I have 2 SATA disks in Raid0, 1 SATA disk for MAC and 1 SATA disk for data. To be able to boot into Windows, my bios was set to RAID, not AHCI. Now, i set this option to AHCI and im able to boot into Mac, but my raid disks are lost, so i cant boot into windows anymore. Is there a fix so i can use my Raid and also be able to boot into Mac without errors?

What SATA controller do you have? With some like Intel you should be able to boot into OS X in raid mode with some extra kext, however I'm not sure if you would be able to boot the raid array from chameleon...

Im using the Intel® ICH10R Sata controller =) And im using a guide to install Snow Leopard, and all guides tell me to use Chameleon RC3, so i hope it can be fixed with some kext, do u know which?

thnx

You could try the legacy kexts from here. It should work with any Leopard version, it contains device id 0x28228086 for ICH10R, if your device id is different you can add it to the plist or find out which one it is and I'll update it.
Keep in mind OS X wont see your RAID array (it will see 2 independent disks so be careful not to format them or anything) and like I said I dont know if Chameleon would let you recognize the Windows array as a boot target, so I'm not sure if this will let you multiboot yet...
