Windows will not start properly — which recovery option should I choose?
Startup Repair, System Restore, Uninstall Updates, safe mode, Reset this PC, clean install — six options on the same menu, ordered here by what they cost you rather than by where Microsoft puts them.

Short answer
In order of least to most damage: safe mode to find out whether it is software at all, Uninstall Updates if it broke after an update, System Restore to undo a driver or program change, Startup Repair if Windows genuinely cannot find itself, then Reset keeping files, and a clean install last. Work down that list. The menu itself is not in that order, which is why people reach for the destructive options first.
The Windows recovery environment is a good toolbox presented badly. Everything a home user needs is there, but the options are laid out by category rather than by consequence, so "Reset this PC" — which removes every installed program — sits on the first screen while System Restore, which quietly undoes the thing that actually broke, is two menus deeper. The result is predictable: people pick the big obvious button, spend a day reinstalling software, and often discover the underlying fault is still there because it was hardware. This guide is the ordering the menu does not give you.
Safety
Step by step
- First establish that it is software at all.Boot into safe mode from Troubleshoot, Advanced options, Startup Settings. If safe mode is also broken, no recovery option on this menu will help, because they all assume a working drive and a working machine. Go and read the guides on black screens and no bootable device instead.
- If it broke after an update, uninstall the update.Uninstall Updates offers to remove the latest quality update or the latest feature update separately. This is reversible, takes minutes, keeps everything, and is the right first move whenever the timing points at Windows Update. Try the quality update first — it is the smaller change.
- If it broke after installing something, use System Restore.It rolls system files, drivers, registry and installed programs back to a saved point, and explicitly leaves personal documents alone. Its weakness is that restore points must exist, and many machines have protection turned off. If there are no points listed, this option is unavailable rather than dangerous.
- Use Startup Repair when the machine genuinely cannot find Windows.It fixes boot configuration problems and nothing else. It is worth exactly one attempt. Running it repeatedly when it has already reported that it could not repair the PC achieves nothing — the log it writes will tell you what it tried.
- Use the Command Prompt for the things the buttons will not do.The recovery Command Prompt is where you check the drive, rebuild the boot configuration, and — importantly — copy your files onto a USB stick before doing anything destructive. It is the least friendly option and the most capable one.
- Reset this PC, keeping files, when the system is genuinely corrupted.It reinstalls Windows, keeps documents, and removes every installed program. Budget a day for reinstalling software and expect to need your licence keys and account passwords. It is a rebuild, not a repair, and it does not fix hardware.
- Clean install last, and only from Microsoft's own media.This wipes the drive. It is the right answer for a machine you are handing on, a suspected deep malware infection, or a Reset that itself fails. Download the installation media from Microsoft's own site, never from a third-party download page.
- Recognise when the answer is not on this menu at all.If the drive is failing, if the memory is faulty, or if the machine is overheating, every option here will appear to work and then the fault will return. Repeated corruption after a successful repair is the pattern that means hardware.
Common mistakes
- Treating Reset this PC as a repair — It is a reinstall with your documents preserved. It removes every program and every setting, and it will not fix a failing drive, faulty memory or an overheating machine — those faults come straight back.
- Skipping safe mode because it seems like a waste of time — It is the only step that tells you whether you are dealing with software at all, and it takes two minutes. Every option below it is wasted effort if the answer is hardware.
- Downloading recovery media from a search result rather than Microsoft — Fake Windows download sites are a long-running and effective malware channel, precisely because the person downloading is already desperate.
If it doesn't work
System Restore shows no restore points
Cause: System protection is off, which is the default on many machines — Fix: Nothing to be done now, but it is worth turning it on once you are back in Windows. It costs a few gigabytes and it is the cheapest undo button the system has.
Startup Repair says it could not repair your PC
Cause: The fault is not a boot configuration problem — Fix: Stop repeating it. Move to safe mode and the update or driver angle, and read the log file it names on that screen if you want to know what it tried.
Reset this PC fails partway through
Cause: The recovery image itself is damaged, or the drive is failing — Fix: This is the point to use installation media from another computer instead. If that also fails, suspect the drive.
The menu asks for a BitLocker recovery key
Cause: Drive encryption, which is on by default on many recent machines — Fix: Retrieve it from the Microsoft account the PC is signed into, or from workplace IT. There is no workaround, and searching for one is how people lose everything.
Everything works after the repair, then breaks again days later
Cause: Hardware — Fix: Recurring corruption after a clean repair points at memory or the drive. Run the built-in memory diagnostic and check the drive's health before rebuilding a third time.
You cannot reach the recovery menu at all
Cause: The recovery partition is missing or the machine fails before it — Fix: Build installation media on another computer and boot from that. It contains the same recovery environment.
Questions people ask
Does Reset this PC keeping my files actually keep everything?
It keeps files in your user folders — Documents, Pictures, Desktop and so on. It removes all installed programs and most settings, and anything stored outside a user folder is not guaranteed. It also creates a Windows.old folder for a limited period, which is worth checking before it is cleaned up.
Which is better, Reset or a clean install?
Reset is faster and keeps your files; a clean install is cleaner and is the right choice if you suspect malware, if the machine has accumulated years of manufacturer software, or if Reset itself fails. For a machine you are passing on, only a clean install with a drive wipe is appropriate.
How do I get my files out if I cannot start Windows?
Either through the recovery Command Prompt onto a USB stick, or by removing the drive and reading it in another machine through a caddy. The catalogue's guide on recovering files from a dead computer covers both properly, and doing this before any destructive option is the single most valuable habit here.
Will any of these remove a virus?
Reset and clean install both replace the operating system, which removes almost all ordinary malware. Neither cleans an infected external drive or an infected backup, and restoring your files afterwards can bring it straight back. Scan the files you rescue before you put them back.
