So I've got a pretty vanilla 10.5.7 install working perfectly on a Gigabyte ga-ep45-ud3r. I'm looking to install Vista x64 on my second sata drive. The way it's setup right now I have Leopard on my first sata drive and nothing on the second drive. Both drives are plugged into the orange/yellow plugs (i.e. not using jmicron) and os x and the vista installer see both drives just fine.

 

However, despite having the second drive with one partition taking up the whole drive and formatted NTFS, Vista does not want to install on the drive. I get the "windows was unable to find a suitable drive for installation" message. The drive is flagged as bootable in gparted so I really have no idea what's going on here. I'm suspecting it might have something to do with AHCI but as I understand it Vista supports this out of the box and as far as I can tell the installer can see and format the drive just fine.

 

Any ideas on how to get this dual boot working? I'm pretty close to simply unplugging my OS X drive and installing Vista on its own then using the bios to choose the OS but I've heard this is a big no-no. How can I make Vista accept the second hard drive as its install drive?

 

Thanks

Hey - was in a pretty similar situation - wanting to install Vista on a separate drive while still hanging on to Leopard. Have come across posts in the forums that Vista has to be the first drive (primary/master) .. so for my situation (which worked) I installed Vista on primary (IDE) drive as it didn't seem to want to go onto anything but the primary, installed Easy BCD bootloader, have my OSx86 drive connected via SATA using an IDE to SATA adaptor (cheap) and

booted into Vista fine.

Only issue was getting back into Leopard, which was fixed by:

1. copying and pasting the boot0 file on install DVD (/usr/standalone/i386/guid) to C drive in Windoze

2. Rename boot0 file to nst_mac.efi

3. Launch Easy BCD, add/remove entries, under 'Add an entry, click on Mac tab, think selected generic x86, name it whatever, then add entry

4. went to manage bootloader section, and select reinstall vista bootloader, write MBR

5. Go back to C folder, should find NST, now move nst_mac.efi file to the NST folder.

6. Restart. Hope.

Found this fix somewhere in the forums, really can't remember where, think it was under dualboot separate HDD search tag.. Thanks to whoever posted it in the first place, helped me out. hope it helps you.

cheers.

Quick Update on the status of my dual boot. Everything ended up working out perfectly in all honesty. Originally I had installed leopard on my first SATA drive (disk 0) and used Chameleon 2 to boot the OS X drive. Chameleon always gave me the option of booting OS X or Windows NTFS. The Windows NTFS option was my second SATA drive (disk1) but I knew it was empty so I never selected it.

 

After getting fed up with the Vista installer I decided to unplug my OS X sata drive and install vista on the second drive (which now registered as disk 0 even though it was plugged into the same port as before). The install went fine and after updating vista a few times I plugged the OS X drive back in. To my complete and utter joy, Chameleon popped up like normal and selecting the OS X drive boots leopard just fine while selecting Windows NTFS boots Vista with no problems. No bios switching, nada. It just works.

 

I'm guessing I owe my thanks to the Chameleon guys on this one.
