Okay, so my last article was huge hit (by my standards). I was trying to setup Windows 8 Developer Preview on my Mac and thought of sharing the experience. Turns out lots of people were trying the same .
After a day of playing around, I was beginning to feel the pinch of VM so wanted to setup Win8 on some hardware. I have an existing laptop running Windows 7 and oodles of free disk-space. So decided to give it a shot.
Before you start here is the configuration I start with
1. Core i5 Dell Latitude with 8 Gigs of RAM and 250 Gig HDD with about 200+ Gig free and Windows 7 Professional OEM installed
2. The same Developer Preview ISO I used for my previous post
3. An ISO mounting tool like SlySoft’s Virtual Clone Drive
4. After a long twitter exchange with one fellow enthusiast, I need to put in this extra warning. You CANNOT setup Win8 on a Dynamic partition using the method outlined here. This will work only if you have ‘Basic’ partitioning. How to know what type of partition you have, in the Disk Manager select the hard disk and the first column on the left will show DiskN, Basic or Dynamic. If you see in the images for the Disk Manager below it shows ‘Disk0 Basic’. So proceed only if you have a Basic parition.
Standard Disclaimer: The below worked for me, the Windows ecosystem comes with so many permutations and combinations that it’s impossible to predict if it will work for you.
If Shrinking partitions/Installing Drivers doesn’t sound like things you can do, DO NOT ATTEMPT IT. Hopefully nothing is affected but if your system is hosed in the process I cannot be held responsible.
Use the below steps at your own risk, no warranties here.
All set? Here we go
You need to do this ONLY if you don’t have a partition that can be formatted. If you already have a partition that you can format, format it and jump to step 2.
With that I end my ‘Setup’ series for Win 8. I promise the next one will be ‘Code to Metal’. Planning to explore WinRT and made a ‘real’ Social App.
Microsoft launched the Windows 8 Developer Preview today at the Build conference. If you like living on the bleeding edge of technology and want to play around with the release, you need a computer to do a clean install of Windows 8 DP. Fortunately if you don’t have a spare computer to mess with, Virtualization solutions are there to the rescue.
I usually use VMWare on OSX to run all my Windows VMs. However VMWare failed to install the Win8 DP. So I decided to install Oracle (formerly Sun) VirtualBox solution. It supports Windows, OSX and Linux as host OSes.
I am of course assuming you have already downloaded the Win 8 DP iso from Microsoft.
Once you have VirtualBox and Win 8 DP iso, lets get started.
Fire up Virtual Box. It will look as follows:
Click on ‘New’
This is a very critical step. If you over-allocate memory the VM setup will fail.
Above image of Task Manager shows 932Mb free on this Win7 System.
Above image from the Activity Monitor in OSX shows free memory available = 516 MB
The example values are very less because I am running two VMs at the moment, but point to note is you need to make a guess of Memory to allocate to the VM based on the above Free Memory available values. So if you see 2.0 GB free then assign about 1.5 GB. Hope this update helps people who are facing setup issues.
I selected VDI.
Keep it Dynamically Allocated unless you want to block off a
portion of your HDD to start off with.
20GB is default and it worked for me. My installation left
about 6 GB of the 20 GB left
Now Click on Start
Here point it to the iso file you downloaded
UPDATE: Some folks have had a hard time in-spite of the tutorial, so that got me thinking and I realized that between the setup failing for me the first time around (that I attributed to lack of memory above) and me getting it working, I also did some configuration changes to the VM that are different from the default shown in Step 10: So here are the final settings that work for me (click to expand). Notice I have enabled Acceleration, given it both the CPU cores to play with (default is 1 only) and given it a healthy dose of Graphics memory. For your system, keep an eye for the Green Line for each setting, don’t stretch beyond the green line in any of the settings. Again, virtualization is tough job simply because of the sheer number of h/w software combinations possible. So if it’s not working for you, sorry to hear that.
UPDATE 2: I just noted on twitter today this site had a very pointed solution to Virtual Box issues on Win 7 http://www.kombitz.com/2011/09/16/status-0xc000025-error-when-installing-windows-8-developer-preview-on-virtualbox/
You can try the above if you are facing the same issue.
