I’m trying to use Rufus to create a few bootable USBs using a Win10 VM. The isos themselves are on an external drive. I have all sorts of ISOs that are known good, from Linux Mint, Ubuntu, Suse, Win 7/8/8.1/XP/10/ServerX all of them are known good, and I can use them to install a Parallels environment no problem.
However, when I’m in Win10, trying to make a bootable USB using rufus, I keep getting an error message that states “The image is either unbootable, or it uses a boot or compression method that is not supported by rufus …”
These ISOs are known to be good. I can use them to install all of my VMs. But I can’t make a rufus bootable USB 100% of the time with it. I tried this on Win10 and Win7, on a win7 clean install it allowed me to create a bootable usb of win 8.1, but when I tried again to create a win10 bootable usb I got the same error message.
Question: WTF is going on?
