CD/DVR R/RW not recognized by BIOS

My son's PC (Dell Dimension 4700, Win XP SP 2) displays a blue screen of death with the message 'UNMOUNTABLE_BOOT_VOLUME'.  It will not boot to safe mode or any other options and always comes back to the bsod.  MS KB suggests thgat this is some sort of HD failure and suggests that Windows be reloaded.  When i tried to reload from CD using the onboard CD/DVD R/RW it wouldn't find the windows CD.  I went into the BIOS to see what the boot sequence was and it does not recognize the CD drive in the boot sequence.  I says the 'Onboard or USB CD-ROM   (not present)'.  When the PC was working, it would read and write CDs and DVDs so I don't understand why the BIOS doesn't recognize the drive.  Any help would be appreciated.

 

My next plan is to buy a USB CD-ROM and see if it is recognized.  The original problem (unmountable boot volume) may require that my son buy a hard drive but I'd like to try loading Win to the drive before throwing it out.  Thanks.

Do you see your CD or DVD, whichever you have, listed under drives in the BIOS?

The DRIVES portion of the BIOS is:

 

Diskette Drive                            USB

Drive 0:SATA-0                          ON

Drive 1:SATA-2                          OFF

Drive 2:PATA-0                          OFF

Drive 3:PATA-1                          OFF

SATA Operation                          NORMAL

 

There is no onbboard diskette drive hence the USB.  I'm not sure whether the CD is SATA, PATA, parallel or serial.

For some reason my colonP is showing up as a smiley face in my previous post.  Please make that substitution when reading it.  There are no happy faces in my BIOS.

Don't worry, I'm used to it. I translate on the fly! :)

 

Ok, those drives listed as ATA-0 and ATA-1 refer to IDE devices, i.e., your DVD drive. If you have two drives, both of those should be turned on. If one, then ATA-0 should be on.

Thanks for the help.  I turned on Drive 2 (PATA-0) and the system found the CD-ROM.  I put it first in the boot sequence and ran chkdsk /r and was able to recover the drive.  I didn't have to reload Windows.  Only one problem, the drive used to be 80 GB I think but is now shown as 75 GB.  I think it may be time to buy a new hard drive and get a copy of Drive Image.  What do you think?

Ok, that's good. You may have lost some room using chkdsk, which will mark and avoid using bad sectors. So I think I agree--time for a new drive. Any SATA drive will work.
