Greetings, I hope that this thread is acceptable in this forum. After upgrading to Windows 8 my CD/DVD unit (a Samsung - TSST corp CDDVDW Sh-S223L) will not be recognized unless a disc is inserted before boot. Then disc can be removed and new one inserted later.
Any assistance appreciated. Stephen
But, if you continue a normal boot, without a disk in place, and, after start up, insert a disk, does it then show? If so, then that is a normal function of Windows 8. It does not load items on start up, unless needed. This also applies to services which only have "on demand" use. It is on of the ways that MS have achieved the improvement in start up time.
