will try to eliminate duplicate thread
Thank you John VV for your two replies.
As for double-posting you are absolutely correct and I do apologize for letting my desperation for an answer make me assume that my first thread was not accepted and sending a second one. However, sometime ago in a previous thread I asked the members of this forum to help me with the installation of Linux Mint and they pointed out that I may have erroneously burned the image on a DVD having simply copied it instead of burning the image itself. So today, using Infrarecorder, as recommended in the Linux Mint manual, I burned an image onto a DVD showing files like "casper" and "isolinux". Now I have the (Microsoft) problem of having the operating system boot from the DVD upon startup. I am hoping someone with Windows 7 professional solved this problem and could share his/her experience with me. Also, I will try to eliminate the thread with two responses so as not to be redundant.
Again, thanks for taking the time to ponder on my problem,
