Having trouble installing Win7 x64 (Windows 7 64-bit) on your mac? Keep getting a Select CD-ROM Boot Type” message when you go to install? Boot Camp have you pulling your hair out?

Some googling reveals the answer over at Jowie.com, but it’s a little confusing to know exactly where to start. Hopefully this step-by-step tutorial makes it idiot-proof. If you need pictures, Jowie’s site has some nice screenshots.

So, without further ado, install Windows 7 (x64) on your Mac (specifically, I’ve done this for a mac mini) in 7 easy steps!

Step 1: Download and install ImgBurn
Step 2: Insert your Windows 7 Install DVD, OR mount your .iso file with Daemon Tools Lite.
Step 3: Extract your boot image:

• Using ImgBurn, go to “Build” mode
• Select the Advanced Tab
• Under that, select the “Bootable Disc” tab
• Select your DVD drive at the bottom and hit the disk icon. If it asks you if you want to keep those settings, tell it “yes”

Step 4: Add your disk to your new disc image

• On the left side, click the folder icon in the “Source” section and browse to select your Windows 7 Install DVD (Just select the actual drive, no files or folders inside it)
• Hit ok.

Step 5: Verify build settings

• Click the options tab on the right.
• System should say ISO9660 + UDF, Revision 1.02
• Click the Advanced tab again
• Click the Restrictions Tab
• Select “Level X – 219 Characters”
• Select ALL 4 checkboxes below
• Click the “Bootable Disc” Tab again
• Make sure “Make image bootable” is checked
• Emulation Type: None (Custom)
• Boot Image: (should already be selected if you told it to use those settings. If not, select the .ima file you saved in Step 3)
• Sectors to Load: 8 (if you’re using Vista x64, it should be 4)

Step 6: Build your new iso

• Enter a destination for your new ISO on the left. (Use the folder icon to the next of the dropdown, or enter a filename in manually)
• Click the big folder pointing at a disc document at the bottom to create your new image!
• If it asks about a Volume name, just hit “OK”

Step 7: Burn your new iso.

• Switch to burn mode.
• Select your NEW .iso file (don’t accidentally use your old iso!)
• Select your destination blank DVD

Click the burn button.

Tada! Pop that disc into your mac mini, or imac, or macbook, or mac pro, or whatever, and you’re set! Welcome to Windows 7!

So I have this 1.66GHz Core Duo Mac Mini (1,1), and it was a bit slow for my new TV tuner, just barely keeping up. Given than Core 2 Duo is so vastly superior, and they’re old enough now to be (relatively) cheap on eBay, I decided to upgrade.

I found a T7400 on eBay for about $150 shipped, which runs at 2.16GHz and is the next-to-best processor that will fit in a current Mac Mini. (Any Intel mini will do, even the old skool Core Solos) You need a pinned model, but I found that I could get the other (solder-type) model from Kaga with “aftermarket” pins for a bit cheaper, (something like this) so I did. It works great.

There are instructions on how to do the upgrade all over the place, but here are three very important notes:

1. Buy a 4-40 bolt set. The nylon fasteners on your Mac Mini are fragile, and even if they don’t break, probably shouldn’t be reused. Most people recommend nylon nuts/bolts, but I could only find metal at my local hobby shop (RC planes and cars use this kind of thing), and they’re working fine. There’s limited clearance underneath your Mini’s mobo, and you don’t want large nuts touching any of the circuitry underneath, so put your bolts in upside-down. Buying bolts that are “too long” will make it much easier to get the nuts on over the springs that hold your heatsink in place. Since I used metal screws, I put a piece of 3M electrical tape (the good 33 stuff) on the metal mobo tray underneath them, just to eliminate any possible electrical oddities.
2. Get your thermal paste right Clean the HS off well with Rubbing Alcohol. Put a small glob (like 2 grains of rice worth) of Arctic Silver 5 (or whatever goo you’re using) on the center of the die. Don’t spread it out, just put the HS on top and fasten ‘er down. If you spread it out yourself, you could get air bubbles and crud in there, which is not good. I did this wrong the first time and found that even with my fan set to 1900, my Mini would idle in the mid-to-high 50s. By reapplying, now my fan is at 1800 and I’m idling in the mid-to-high 40s.
3. Use smcFanControl. Set your minimum fan speed to 1800, because the Core 2 Duos run a little hotter than the Core Duos.

That’s it! My “new” Mac Mini (now with 2GB of RAM and the 2.16GHz processor) just flies, and it benched at somewhere around 30%+ better with XBench. The real story though is in how it “feels,” which is about twice as fast–I don’t hit that ceiling anymore where everything just starts acting like crap.

So… if you’ve got an Intel Mac Mini, upgrade already! You won’t regret it! (Just make sure you get your thermal paste right…)
