Well I thought I wrote about this already but in fact I didn´t – anyway – if you´re looking for a kick ass partition manager / editor then be sure to check out the gParted Live CD.
It´s open source and therefore available for free at : http://gparted.sourceforge.net/.
If you need to do anything with your partition(s) – resize, move, delete, format, manually edit MBR and other crazy shit gParted Live CD is your choice. It boots directly from the CD, can also be adjusted to boot from a usb device and performs any desired action with your partitions.
I´m using Sun´s VirtualBox for a while to host multiple Operating Systems on my machine. I discovered that it is not possible to re-size fixed disk images without doing a completely fresh install of that virtual machine. I found a quite helpful post at Nick Heppelston´s BizTalk Blog to solve this problem.
I found this fascinating quote today:
In my previous post I extolled the virtues of Sun’s desktop virtualisation software, VirtualBox. One thing niggled me though – I couldn’t easily expand a Virtual Disk Image (VDI) and was regularly reaching the space limits of the modest 20Gb disks I was creating; I needed an easy way of expanding disks before I could use it as my main virtualisation platform and felt comfortable in recommending it to my readers.modhul.com, Nick Heppleston’s BizTalk Blog, Dec 2009
