Can boot with Win7 DVD but once logged into Win7 CD doesn't work
I have an HP laptop nc6400 running Windows 7 SP1. I am having problems with the CD player - it doesn't recognize any CDs I put in! When I try to put in a CD, it ejects the drive and comes up with the message "Please insert a disk".
I have a Win7 SP1 (burned) disk. When I put in this disk, and boot from CD drive, it launches the Windows 7 install program. I select the "repair" option, and repair startup files. It completes without errors. (This is the same disk that wasn't recognized once in Win7).
Someone recently replaced the CD player with a different one - both players had the same problem (it is now a HL-DT-ST RW/DVD GCC-4247N ATA Device). I've tried updating the driver (in Device Manager) and even uninstalled it and had it re-discovered and installed.
When I run SFC /SCANNOW from the boot DOS prompt, it says "No errors".
When I log into Win7 and run SFC /SCANNOW from an elevated command prompt it says there were files that were corrupted but unable to fix. I created the SFCDETAILS file, but searching for "fail", "corrupt" and "unable" yields 0 results, so I don't know what files are corrupt.
I'm not a hardware person, and this is a work computer, so I have limited ability to do anything hardware-wise. But considering the DVD player works to boot from, but doesn't work once logged into Windows, I'm thinking it's a software problem (but don't know what the problem is).
Any suggestions would be greatly appreciated!
