Can't burn CDs/DVDs
HP/Compaq Elite 8300, W7 Pro 64bit, 8Gb RAM etc. Installed DVD player plays CDs and DVDs but won't burn anything. I have an EXTERNAL USB player which works fine but have just installed another INTERNAL player and, again, won't burn CDs or DVDs. Device appears on the device list and drivers are reported as installed and "ready for use". I'm trying to burn a System Repar Disc but when I select this option in Control Panel, it reports "unable to find a CD/DVD player" (or some such message.) Any suggestions, please?
