I have googled, searched on this forum but all answered provided have not yet solved my issue. Am trying to write the VGA image(v. 17.7.5) on to a USB drive so as to install on my desktop pc with the below specs;Model: Dell optiplex 755 BIOS : A22RAM: 2GBHDD:160GBI have tried using all softwares i.e rufus,win32 disk imager but with no luck. Rufus says the "image is either not bootable or is not supported by rufus" while win32 disk imager will write to disk but when i plug onto my Druplex.
