Hi, please view my post that teach you how to resolve your problem. I have spent a lot of time to search this solution and work 100%. Reguard
Unfortunately your ‘solution’ neither works for OS X users (since @sinovoip provides incompatible ZIP archives) nor for Windows users that use FAT32 (4GB size limitation so you end up with corrupted images anyway since @sinovoip provides only bloated and large images exceeding this size instead of resizing fs/partitions and do an auto resize on first boot)
what a pity…my solution is for linux users…'cause I only use linux Mint and windows 7 on Virtualbox. I will try with Osx soon.
