Missing DVDRW in windows and device manager, also unable t boot from a disk

[Reddwarf4ever]

Hi
for some strange reason the DVD writer; CDRW is not showing up in windows or in device manager. Inserting a DVD has no reaction whatsoever from the laptop.

i have tried says file checker , looked for the relevant upper registry entries, but found none. Have unplugged and reinserted the CDRW just in case.. also ran the hardware troubleshooter.

i desperation I have wiped the HDD and clean installed W10 Home 32 BIT. But made no difference.

i the device manager there isn’t even a heading for CD / DVD/RW, thought this should be there even if unpopulated !!!

any help would really be appreciated

UPDATE
found an old post similar to mine, tried deleting IDE channels 0 and 1 but avian made no difference....

Just checked the relevant registry key to delete the upper and lower filters but found 22 registry entries with the same key name, should this be so ?......can’t delete any of them...HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e967-e325-11ce-bfc1-08002be10318}

Welcome back to HP Forums. 

I have gone through your Post and I would like to help

I suggest you run a Hardware Test on the DVD drive to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Optical drive

Keep me posted

Thank you
