Now double click on the ‘bz2’ file to extract it (in this instance called ‘VMware-VMvisor-big-3.5.0_Update_3-123629.i386bz2’.
We are now at the stage where we’ll use the ‘dd for Windows’ utility to apply the image you just extracted to a USB pen drive.If you have any Win RAR windows left open you can now close them as we will only be dealing with the file with the ‘dd’ extension you just extracted.I really like the idea of having a bootable ESXi USB key around as it is useful for quickly spinning up an ESXi install on one of my lab machines.For this project (and also because I didn’t have any spare USB keys or sufficient capacity lying around) I went out yesterday and bought 2 x 2GB USB keys (for £9.99).However with the introduction of VMware ESXi 4.0 there is an option to select USB pen drive as a target during the installation process – this being the easiest method of all.
I have used both methods successfully but others have reported some problems when using ‘DD for Windows’ under x64 Vista.
TGZ file when this file is abstracted you will find the required ‘dd’ image file in the directories outline below: Now onto the first method…
Firstly we want to extract the relevant ‘dd’ file from the VMware ESXi ISO image so that we can then apply it to the USB key.
Just a reminder that you can download VMware ESXi for free from here. If you haven’t already got this installed then you should as it’s very useful. 1 x Roll of Cello tape 1 x Pair of Scissors 1 x Clothes Peg 1 x Squeegee Bottle Ok – so ignore the last 4 items 🙂 There aren’t really any differences between creating a ESXi 3.5 or 4.0 bootable USB pen drive apart from the obvious difference between the actual image file names.
Both of the ‘dd’ image files that you need are located in the INSTALL.
To get your USB key back to its original capacity download the HP USB Disk Storage Format Tool from here and run it against your USB key.
