The consequences of installing Chromeos on the stick

Even in the summer I decided to try out Chrome OS, put it on a USB flash drive , Transcend 4Gb JF V60.
Did everything right, with the utility of one recorded image on a flash drive, after the NIB is loaded. But the download failed, error was some sort. I do not remember what it is.
After I decided to reformat the flash drive is formatted. And that's all. She was gone.
On other computers it works fine, but it's on my laptop Acer eMachines e625 — sees.
Waiting for advice, because I started the semester and stick.
