Common Dell Error Codes
Dell systems display specific diagnostic codes and Windows errors when a hard drive or operating system fails. If you see any of these on your Dell, bring it to us for fast diagnosis and repair.
No Boot Device FoundYour Dell can’t detect a bootable drive – often caused by a failed hard drive, loose cable, or corrupted boot sector.
INACCESSIBLE_BOOT_DEVICEA Windows blue screen error (BSOD) meaning the OS can’t access the system drive. Common after updates or drive failure.
ePSA Error 2000-0141Dell’s built-in diagnostics detected that no hard drive is present – the drive may have failed or disconnected.
ePSA Error 2000-0142Dell diagnostics found a hard drive self-test failure – usually indicates the drive is failing or has failed.
CRITICAL_PROCESS_DIEDA critical Windows process stopped unexpectedly – often caused by corrupted system files or a failing storage drive.
UNMOUNTABLE_BOOT_VOLUMEWindows can’t mount the boot partition. Typically caused by file system corruption or physical drive damage.
Operating System Not FoundThe BIOS completed POST but can’t find an OS to load – the drive may be dead, disconnected, or wiped.
KERNEL_DATA_INPAGE_ERRORWindows couldn’t read data from the drive into memory – a strong indicator of physical hard drive failure.
S.M.A.R.T. Failure PredictedDell’s pre-boot check detected the drive’s self-monitoring system reporting imminent failure. Back up immediately.
Automatic Repair LoopWindows keeps restarting into repair mode without fixing the problem – often caused by corrupted system files or a dying drive.

Mount Vernon Computers is my go to computer repair shop every time I have a problem or need help with my computer. Daryl is so nice and professional that you’re not scared to ask a question. He has helped me get a computer with motherboard problems repaired and another computer with GPU problems fixed. I got a new computer and needed help so I called them and Daryl was kind enough to do a video call and walked me through my problem and eventually solved it! 10/10 Highly recommend!Read full review

Usually a failing drive or a setting change. Stop restarting it and call us so we can protect your files.
Why is my Dell not charging when plugged in?
It’s commonly the adapter, the charging port, or the battery. We diagnose which one and replace only what’s needed.
