If you have a mac and are unsure on how... (not sure why any mac-owner wouldn't be comfortable with the terminal window but,)
Instructions to use xdissent's ievms script from github:
Yes. I couldn't get the IE6 disk to work but IE8/Windows 7 works nicely.
Note that you shouldn't need cabextract but you may have to install p7zip-rar to extract the exe/rar files.

And they also can't reply directly to his comments.
While not free, another option that will take up significantly less space is installing VMWare with Windows 7, then then installing IETester. This is also nice because you only have to run one virtual machine "allows you to have the rendering and javascript engines of IE10 preview, IE9, IE8, IE7 IE 6 and IE5.5 on Windows 7, Vista and XP, as well as the installed IE in the same process."
"...this is an alpha release..." Not exactly what you want to hear when you're testing... I already have enough problems trying to run an actual version of IE6 on Virtualbox
IETester has been in alpha forever. Not sure if it's because of lack of commitment from the developer or what, but it's very buggy and always has been.
I've run into some odd quirks with IETester and similar tools where they don't run exactly like their actual brethren. It's probably fine for the 95% case, but that other 5% can be infuriating. It usually manifests itself as the page working fine in IETester and your customer being adamant it's broken in IE 8 (or whatever).
A little twist on that I use is setting up three XP IE6 machines and upgrading IE to 7 and 8 in two of them (for IE9 you still need Windows 7). Takes up significantly less disk space and RAM; the downside is you have to repeat the procedure every few months.
Note: you need to duplicate the vhd files using VBoxManage, since straight file copies share UUID and you will not be able to add them in VirtualBox):
I did something similar to this a while ago, but I had issues because the UUIDs of the disk images were all the same, so VirtualBox couldn't recognise all of them at once.
Not sure if Microsoft's fixed that yet, but if not the magic words to change a disk image are: VBoxManage internalcommands sethduuid
Or install MS VMs for IE7, 8 & 9 with one command: https://github.com/xdissent/ievms
