I did the format like a usb drive used your method, and now the program is not reading the disc. am I doing anything wrong?
Well, we don't really know if you're doing it wrong or not... partly because none of us use DVD-RW disks, and we haven't yet convinced you to try DVD-R, DVD+R, or a USB drive instead. There are other problems that you can be having, and DVD-RW is just one.
Another possible problem is: formatting. If you formatted DVD-RW disk like USB, and if you used the "Write image" feature of your burner program... and if it still doesn't boot, then it may be that you needed to format your disk as CD/DVD instead, and "Write image" to it again. The "Write image" process must make the DVD
bootable to install Linux.... maybe formatting as USB and as CD/DVD will both work, or maybe neither will work... we don't know.
Another possible problem is: completed download. We also do not know if you have a good download of the Linux Mint .iso file. If you are trying to burn an incomplete or corrupted file, it is just about guaranteed to fail. There are ways to test if you got a good download, but at the very least look at how big the .iso file is.... it should be in the neighborhood of 2 GB if it is Cinnamon or Mate editions. How big is your .iso file?
Do you want to download and install a free utility that can check the integrity of your download file, so you can be sure that it is usable? If yes, one that many of us recommend is this one:
https://bhoover.com/how-to-verify-checksum-windows/. If you get this utility, tell us exactly which version of Linux Mint you downloaded, and we'll explain how to run the test.
Cheers
