If Dell SupportAssist OS Recovery will not reset your PC, first note the exact error and which options appear; the available recovery route depends on your Dell model, processor, and whether its factory recovery image is available. Back up files if you can and keep the computer connected to power before trying any reset. If the factory-reset option is missing, Dell may still offer another recovery path.
Before you try the reset again
- Back up important files if Windows or the recovery environment is accessible. Dell warns that resetting permanently deletes hard-drive data and removes programs or drivers you installed. You may need product keys for licensed applications, and non-factory programs must be reinstalled. Read Dell’s reset guidance before confirming deletion.
- Connect the computer to power, and make sure you have time to let recovery finish without interruption.
- Write down the exact error message and note whether SupportAssist OS Recovery opens, whether Start Reset appears, which reset choices are listed, and whether the PC can connect to Wi-Fi. These details help distinguish a missing image or unavailable option from a reset that starts and then fails.
Check whether your Dell supports SupportAssist OS Recovery
SupportAssist OS Recovery is not available on every Dell computer. Check the exact model against Dell’s support matrix before repeating steps intended for a different system. Availability and recovery choices can vary by model and system state.
Dell specifically says SupportAssist OS Recovery does not support Dell computers with Qualcomm processors and recommends trying Windows Push-Button Reset first. That Windows recovery option is an alternative, not a SupportAssist OS Recovery reset. Follow Dell’s Windows Push-Button Reset instructions for a Qualcomm-based system.
If “Reset to factory settings” is missing
A missing factory-reset choice does not by itself prove the PC has a hardware fault. Dell says SupportAssist OS Recovery may show only Reset and update when it considers the PC irreparable or cannot detect the factory-installed operating system. The choices depend on the computer and recovery state.

Dell’s reset guide distinguishes the options: Reset to factory settings returns the operating system and default software to the state supplied by Dell; Reset and update installs a newer operating system with critical drivers and applications. Review the options and their consequences in Dell’s reset guide. Do not choose an option unless you understand that resetting deletes data and installed programs.
If SupportAssist says it cannot find the factory image
If the local recovery image is absent, corrupted, or needs repair, BIOSConnect may be able to restore it on supported newer Dell computers. It is model-dependent, so check Dell’s BIOSConnect recovery instructions for your system.

Choose the recovery route that matches the problem
| Route | What it does | Important constraint |
|---|---|---|
| Reset to factory settings | Returns the OS and default software to the Dell-shipped state. | Depends on the factory recovery image; deletes data and installed programs. |
| Reset and update | Installs a newer OS with critical drivers and applications. | Availability varies by model; Dell OS Recovery Tool use requires a SupportAssist OS Recovery USB key. |
| Cloud Restore | Downloads and installs the latest available OS for the Dell computer. | Requires an active internet connection and a USB drive with 16 GB capacity. |
| BIOSConnect | Can restore a recovery image when its partition is missing, corrupt, or needs repair. | Supported models only. |
| Windows Push-Button Reset | Provides a Windows recovery alternative Dell calls out for Qualcomm-based systems. | Use Dell’s Windows-specific instructions; it is not a SupportAssist OS Recovery path. |

If the reset still will not start or completes with an error
- Record the exact error text or code, the Dell model, and the point at which the process stops.
- Check the model’s recovery eligibility and requirements using Dell’s support pages above, then try only a route listed for that system.
- If Dell recovery remains unavailable or reports another failure, use Dell’s hardware diagnostics and support route with the model and error code. The right next step depends on those details; Dell does not document one fix that resolves every failed reset.
