I bought my new Dell Vostro 5460 Ultrabook two months ago and did a Back Up and Recovery Disc using a USB flash drive. However now I'm thinking I should have done it using optical discs instead so I can have the flash drive free. I tried burning the contents of the USB into optical discs, but the file size was too big for a single disc, and the disc didn't eject out for me to insert another disc in (as it would if I had done the back up with discs in the first place) - it simply didn't burn at all.
Is there any way I can make another back up using the optical discs this time, and how do I go about that (as my Dell Back Up and Recovery app no longer shows the Recovery Media tile)?
