Windows 7 DvD Missing After Re-install

MICKFREE · 23 Apr 2016

This is an HP DV6700 laptop.
- tired copying back the old installation but ran into issues moving directories from windows.old to the windows directory. So i got frustrated created a bootable usb with vista and re-installed vista still no cd-rom it seem like i tried all the posted fixes several times. But no luck. I have other devices listed in and message that new hardware is detected but it can install the drivers. I downloaded the driver and copied to the drivers and inf folders but no luck. Soo im at the point of installing Win 7 with a usb DVD, but and the moment don't know if the cdrom will appear.

Mick sorry late reply but I just don't undrstand why the device is showing in the BIOS yet not anywhere else?? So nothing at all in the Device Manager??

Nothing in device manager saying dvd\cd
Bios give option for CD.

Bios give option for CD

Ok mate so I have it right the BIOS only gives an option for an optical drive boot choice? it doesn't actually list the optical drive as such - usually the devices have their brand or some wort of serial number listed in the BIOS. Any chance of a pic of the BIOS as opened it should be and I stand to be corrected the General or the first section as you open the BIOS. see pic

Speccy might be helpful. It will show exactly what hardware is picked up as installed.

Example from my computer.

Okay here is the latest I rebooted my machine went into my BIOS the bio show the option to change boot order and the option for CD DVD to be disabled and running however when I reboot my machine and press F9 to change boot order the CD does not appear in the list only my hard drive in my thumb drive that I had inserted I tried to remove the CD ROM boot up where it's not detected power down reinserted boot up and it's still not listed in the boot order my BIOS doesn't look like the files listed on the screen where I have the option for the CD to be set up or install so I'm anticipating that I'm having a hardware issue with it not being detected on the motherboard.

Yes well the BIOS should have any device listed like the pic I only used that as an example it might take some digging around in the BIOS settings to find it.

In addition to Layback Bears suggestion this is also good for finding details and in quite some depth too on your machines internals.
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/-
12v = 11.4 – 12.6v
5v = 4.74 – 5.25v
3.3v = 3.135 – 3.465v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
Power Supply 101: A Reference Of Specifications - Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

Use PART B: Have attached two example pics
