Dvd-Rom Drive not recognized, not upperclass fix.
Alright, i have got my laptop, HP Pavilion Dv6700, upgraded to Windows 7 Professional x64, and i ran it previously on both beta, and RC verisions of Win7 without any difficulties. But now, my Dvd-rom is not being recognized by my computer, once Windows boot's up. As its a laptop, while in bios, the Dvd-rom is given power, can open close, but when Win7 starts, it wont even open any longer and is not viewed in the computer screen. Also under the drivers section, it shows ATA Channel 0, ATA Channel 0, ATA channel 1, ATA channel 1. All of which claim to be the most up to date. One of the key problems is i cannot even boot to dvd, to try to reinstal Win7, it starts to read the disc, then skips immediatly to booting from my HD, even with boot to dvd set to priority.
Now what i've done, ive tried the Upper/Lower class filter fix, gone into the Registry, and looked for those, and i do not have those filters on there, i have also done the manual run command for the same problem "Bcdedit /set Ddisable_integrity_checks" and rebooted my laptop, without any change. I have also uninstalled each of the ATA Channel drivers, and rebooted my laptop, still, no change.
Now i suspected that it was my laptop Dvd-rom drive going out, but i just recently discovered my desktop is having the same exact problem! So i jumped onto some virus scanning programs, and found my systems clean, so far, but i know that doesent mean much. I did the same steps above for the desktop, and the Dvd-rom drive remains unrecognized, though as it has its own power source, can open and close. I -know- the desktop's drive is not bad, as i recently installed it last week, when the original drive was bad, so i could reinstall Win7 RC x32 on my desktop.
At this point i dont know what more to do, besides possibly reinstalling Win7 with a flash drive on my laptop, to see if it can see my Dvd-rom again, because when i first installed Win7 Professional, it viewed my Dvd-rom fine. Anyone with any tips, please get back to me!
