I've got a DVD ROM and A CD RW. I've uninstalled my CD RW and installed a DVD RW in it's place but I've kept the exisitng DVD ROM. I've re-booted and now my PC can't see the D and E drives which is where the DVD ROM and CD RW were previously. The annoying thing is that I only uninstalled my CD RW leaving the DVD ROM as it was but when I checked on the hardware devices the DVD ROM has disappeared too! Can anyone help me please!!!
