In windows 10, I'm trying to install ubuntu with USB. For making bootable USB, I'm using rufus. However, there occurs an authentication problem even though I logged in Windows with an administrator account.
Here's the log from rufus.
Will reuse 'ldlinux.sys' and 'ldlinux.bss' from './rufus_files/rufus_files/syslinux-6.03/20171017/' for Syslinux installation

It seems like there's some problem during locking. How can I solve this?
ABORTED: Cannot use an image that is located on the target drive!
The line above means that you are trying to write the drive on which your ISO resides. This is the equivalent to sawing the branch you are sitting on!
Of course, Rufus cannot erase a drive if the image you want to apply resides on that drive.
Please remember that Rufus always repartitions and reformats a drive, so you cannot use anything from that drive, especially not an ISO.
The solution: Move your .iso file somewhere else that isn't the USB drive you are trying to use with Rufus.
