Pavilion dv6915nr CD/DVD drive missing

[focus2]

The cd/dvd drive is missing from my pavilion OS.  The drive does not show up in the explorer view and when the drive is chosen in the BIOS to boot, it does not.  I have read all the posts on the filter edits but that has not solved the problem.  Is there another solution other that a reinstall?  The CD/DVD category does not even exist in device manager.

Remove the CD/DVD drive,after unplugging power cord and removing battery. Boot up without it, then shut down and reinstall the drive. Many times this will allow the BIOS to redetect it.

If you need help with removing the CD/DVD the Maintenance & Service Guide is HERE

I have completed that process which was mentioned in other posts.  Still the drive does not appear.

Pavilion dv6915nr CD/DVD drive missing (Windows 7 Enterprise, No filters No Device Manager show No Microsoft Fix It detection)

I have a temporal but consistent solution.

Once:

                Hp downloads use the current bios update.

                Download the Microsoft tool Devcon.exe http://support.microsoft.com/kb/311272

Every time that the Optical Drive is missing:

1. Restart the Drive, Ac power off, battery off, Optical Drive off, Optical Drive on, battery on.
2. Like Administrator in command-line type and enter:

                        bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECK

(Thank you HP for the no signing support driver, no clicks for HP)

                        [Devcon.exe installs Directory]/i386/Devcon rescan

Thank you Kudos 10 clicks for you effort.

None of this resolves the UN-BOOTABLE ATAPI DVD Drive issue, I've been having this issue for at least 1 year and a half. This machine will just NOT BOOT from DVD, internal or otherwise. Yes, BIOS is set to detect and try to boot from these devices before the on-board HD but nothing boots other than basic CD which of course is worthless when it comes to trying to restore the system back to factory original settings from the HP Recovery Disk set.

Anyway, I'm glad I know how to get around these freaken issues, but wish I could fix the no boot from DVD issue, I'll try something else, Ill report back.

Well all is not bad, I report a successful re-balling of the NVIDIA chip for my dv6915nr. I'm pretty pleased with that outcome!
