XPS 8500 Windows will not boot after replacing CMOS Battery

There are 2 or 3 or 4 settings in SATA OPERATION.

INTEL RST aka IRRT or ATA or AHCI or RAID AHCI or RAID ATA.

Common Error is STOP 7B or windows had a problem inaccessible boot device.

No amount of reset CMOS or Startup repair FIXES PHYSICALLY BAD DRIVES.

Reinstall from scratch on a new Drive is likely the only Remedy given the age of the drive.

I have RAID or AHCI as an option.

Why do you think this is a drive issue. I added a screen shot of my error message.

Thank You

Most Obvious issue would be INTEL IRRT VS AHCI VS RAID VS ATA under SATA OPERATION in bios.

Try Setting RAID AHCI,  if that doesnt work try IRRT,  (INTEL RAPID RESTORE TECHNOLOGY)

I was able to remove the HDD and take it to work. I connected it to my work PC and was able to view this as if it were a jump drive. I was able to get all of my files off of the drive, so I know that the drive is still functional.

Any words of wisdom or suggestions before I do a fresh install of Windows 10.

Thank You

Where exactly do I change this in the BIOS. I'm assuming F2 on boot up, Drives and then try to find SATA Operation. would this be correct.

Thank You

Correct. Once you're in BIOS setup, just navigate around the settings screens to find the SATA Operations option.

I only have SATA Mode, there is no SATA Operations. My only options are AHCI and Raid.

When i have it on UEFI boot mode and AHCI i get the blue screen and the message is Bad Config error.

When i have it on on UEFI boot mode and Raid then i get the blue screen critical process error as stated earlier in the post.

At this point you will probably have to do a clean install, using the instructions at the link that Philip posted previously.

If your personal files aren't backed up on external media, you will lose everything, unless you either (a) install this HDD in another PC as a secondary drive and copy your files or (b) install this hard drive in an external drive enclosure that connects to another PC via USB to copy your files.

Ok, I will give that a go this evening.

I have already removed all of my personal files form the HDD and put them on another PC.

I will provide an update once I give this a shot.

Thank You

I was able to perform a clean install of Win 10, using the Media Creation Tool as discussed above.

I now have Win 10 loaded and working. I still have the arduous task of re-installing all of the my programs and drivers, which is fine.

I followed Philip's procedure, and deleted all older partitions and installed the OS on one. Is it necessary to go through the Intel Rapid Storage Technology Application step in the Driver installation list.

Thank You to everyone who offered their assistance.

Greatly appreciated.

Glad you got it working again. :Yes:  :Yes:

You do want the Intel Rapid Storage Technology, so you probably should follow that step.
