In need of a multi-OS, bootable USB? Use an Android phone.
I found myself in the position recently whereby I had two hosts I bought off eBay (as one does for labs), they arrived, I had great plans… But no iDRAC Enterprise :( While the iDRAC Ent cards were on their way to me I couldn’t help but want to install ESXi on these things so they were ready to go (old Dell R610s are seriously good value now). One slight problem....
