Using Parallels to run Windows on a MacBook

I haven’t added anything to the blog for a few months as I’ve been busy on a number of fronts. First I’ve swapped over to using a MacBook for day-to-day development. It took me a while to get used to, especially as the keyboard layout in the UK is different from the PC–and it took me a while to discover that that # is produced using ALT-3 and isn’t even shown on the keyboard. But I love it! It works really well.

I use IntelliJ and Eclipse for development with Firefox for Java, PHP and Web development so it’s not much different. MS Office 2004 for the Mac is very different from Office 2003 for the PC, but all works as expected (though there’s no plug-in for the docx format yet). It’s very nice having Unix under the hood too.

However, there are a couple of things I still need a PC for, and the most important of those is running Internet Explorer so that I can test web pages. I have other PCs lying around, so I could use those, but the solution I’ve gone for is to use Parallels (www.parallels.com). This allows you to run a Windows virtual machine (and Unix if you like) at the same time as MacOS. So I have MacOS for development and then Windows in a window. Windows has access to the DVD drive and internet and behaves just like the real thing–well it is the real thing (you do need a Windows operating system license to install it). So I can run Internet Explorer and any other PC-only tools on my Mac whenever I need them.

Replacing your hard disk

A friend of mine had that dreaded moment when his main PC wouldn’t boot. Backups? Yes, well I was going to get round to it….

I suggested that he should insert the Windows XP CD and see if he could boot from that. He was lucky and he was able to do that and get Windows XP to repair itself enough to run up and view the data on the hard disk, in fact for a while it did seem to work.

But this obviously wasn’t going to last for long, the primary hard disk was definitely on the way out. So he needed to replace the hard disk. But that’s always a pain because you have to re-install everything from scratch and that can take days.

Instead, he bought a new hard disk, borrowed my hard disk external USB caddy (which you can find on the net for about GBP20) and downloaded a bit of software called Acronis True Image 9.0.

With this he was able to make an image of his old hard disk. He then replaced the old hard disk with the new one and amazingly enough it booted with pretty much everthing there.

It wasn’t quite transparent, here’s what he told me afterwards:

Some but not all of the registry details are lost when you copy the disk. There does not seem to be any particular logic to the ones that are lost. However, as I think I told you – Photoshop needed to be “re-registered”. I had to boot Windows from the installation disk – (so far only once) but didn’t actually have to re-register it with Microsoft. My Palm Pilot needed to be re-registered. Similarly, almost all the bits of hardware that run off USB ports need to reload the drivers.

Nevertheless, a lot quicker than starting from scratch.

On the other hand, the main advantage from starting from scratch is that there ends up being loads of software you never do re-install, so it is a good way of weeding out stuff :-)
