So I am stuck there. Does anyone know how to fix this? Thanks. I am using UltralISO 18.104.22.16837 free trial version on Windows 10.
Update: I tried PowerISO, same issue, does not allow me to select target disk drive. Is it possible that I did not compress my files to iso correctly? What I did was compress the folder that contains the files, and change the file extention from
.ISO. The second time I used PowerISO's compress option, but none of those methods make PowerISO or UltraISO let me select the disk drive.
Also, does copy the files and paste them into a formatted USB drive work for Windows 7 installation?
