I recently blew away all my low power vm lab running XenServer 6.5 ( http://www.hardstaff.com/lower-power-vm-lab-pt-ii/ and http://www.hardstaff.com/lower-power-vm-lab/ ) and installed Vmware ESXi 6.0. Why I am not exactly sure but I just got bored with XenServer. Not that it’s doesn’t work or anything, in fact in my environment it did probably mostly everything I wanted. However I usually do this once a year, ie just blow it all away and start again 🙂
For more info on that see here http://www.hardstaff.com/esxi-6-0-on-low-end-hardware-part-one/
So I had a bunch of servers to reinstall and didn’t want to have to use CD’s (I didn’t have any blanks) and I had found this software last week while looking for ways to make a bootable Ubuntu USB key. Universal USB Installer
Now at first glance this does not look like it will ESXi etc however I gave it a shot and it works perfectly. So what you do is this. Download the software is a good start, no need to install, it runs from where you saved it, then follow screenshots.
From the drop down menu select the last option
The select your ESXi 6.0 ISO
Then select your USB drive.
Now each time I id this I selected the format option and it always worked. I also found that selecting Windows 8 the using the Windows Server 12 ISO works fine also.
