I downloaded a chrome OS into my flash drive about two months ago and didn't like it, so I stopped using it, I needed to use my USB today and couldn't because the 16GB USB said that there was only 1GB available. I found a solution on Google which didn't work at all, it said to go to Disk Management and find my USB, then delete all the partitions, now that I did, when I put in my USB nothing happens, please help!
