I have been using an old version of Acronis True Image for the last few years to clone my C drive to keep a copy of it. It makes the life easy as it can restore the entire C drive in just 10 minutes if something happens to my system, which otherwise would have taken half a day to full day with installing OS, Office, and other software I use. I would have also lost all the settings and any important files I have stored in C drive (I always keep the important files in other drives).
I just have the bootable rescue ISO file and not the entire software. I felt this the only thing I need and kept a copy of it in the system. I burned the ISO to a disk and have been using it since a long time. Few days ago, my system’s CD drive has failed and system was not booting from the CD drive and I had to take the backup of my system as Windows 10 is going to replace it. I want to keep a copy of it, so that if something does not work in Win 10, I can get back to Win 8 in few minutes.
So, I used Rufus to burn the ISO to USB drive and tried to boot from it, but in vain. I tried it with Windows USB/DVD Download Tool and failed. I searched in Google, but didn’t find a resolution to it. All the solutions required the complete Acronis True Image software. Someone hinted in a forum to try with YUMI to create a bootable USB drive with option to load the ISO from it. I have tried various options in YUMI and succeeded. Following are the options, which worked for me.
Download the YUMI – Multiboot USB Creator here. It is a small software that does not need installation. Open it and select your USB device in Step 1. Check the Format option if you want to format it. In Step 2, select the option “Try Unlisted ISO (GRUB),” then click “Browse” and select the Acronis True Image ISO you already have in the system. Then click “Create” and you are done. When you restart the system, press F8 to select the medium to boot from and select the USB/Pen Drive. Follow the options to select the True Image ISO and boot. You are done.
