I still have not been able to get the Rescue Media to boot. (from Macrium Reflect standard version trial) I think it is because I went from Win 8 to upgrade in store to Win8.1....I finally decided to get the trial version today. It downloaded software for the rescue disk, but STILL did not work. It kept saying put in a rewritable disk or clean disk. I even tried to hit rebuild I don't know how many times, and finally just went to ISO copy, and then burned it with the Cyber Link Media Suite. It didn't give me the option to burn it slowly, it only went max speed, that may also be a problem. I changed dvds, finally went to a cd...and then I put the ISO on that. I had an option of PE3, or PE4 at first. (I chose PE4) But now I think I should download PE5, since it is for Win8.1... For those familiar with this, please advice.
