Free, for good
Linux and GreyHaven cost nothing. No licence to buy, no subscription, no trial that runs out.
Close the window, and open the door to Linux.
Software that makes the switch to Linux easier than ever.
GreyHaven runs on Windows, for people who are still on Windows. Open this page on the PC you'd like to switch, or .
What you get with Linux
No surprise restarts
Security updates install quietly, and Linux doesn't restart your PC in the middle of your work. You restart when it suits you.
No ads, no account
No ads in your menus and no online account needed to sign in. Sharing data with the makers is something you opt into, not out of.
New life for older PCs
Linux runs on most PCs that Windows 11 turns away, including ones without the newer security chip (TPM 2.0) or a recent processor.
Your PC, your rules
Nothing gets installed that you didn't ask for. Thousands of free apps are a click away in the app store, and you can change anything.
Will your games work?
Thousands of Windows games run on Linux through Proton, which comes built into Steam. Check yours:
From ProtonDB player reports (their published data, Open Database License) and Are We Anti-Cheat Yet. Online games whose anti-cheat blocks Linux are the main exception. Searches stay in your browser; cover pictures come from Steam.
Why people make the switch
Windows 10 support has ended
Over a year since support ended
Microsoft stopped updating Windows 10 on 14 October 2025. Security updates now only come through Extended Security Updates, which end on 12 October 2027.
- "This PC can't run Windows 11." Plenty of good PCs don't meet its requirements.
- Ads and nags. Suggestions in the Start menu, prompts to sign in, offers to try things.
- Updates on someone else's schedule. Restarts when you least expect them.
- Privacy. More of what you do sent online than people are comfortable with.
- A PC that's getting slower with every year of updates.

So why doesn't everyone switch? Mostly, it's not knowing whether their PC will work with Linux. That's the first thing GreyHaven checks.
How it works
Download
Install GreyHaven like any app. It's free.
Scan your PC
It checks every part against Linux's own driver lists, in about a minute. Nothing on your PC changes.
Pick your Linux
Ubuntu, Linux Mint or Pop!_OS: it suggests the one that fits your PC, with plain pros and cons.
Switch, step by step
It makes your USB stick, puts the next steps on your phone, and restarts your PC into Linux to try it first.
Sometimes there are two good paths
When the best fit for your PC needs a setting changed, GreyHaven offers an easy path and an advanced one, and you choose. Here's a sample PC with an NVIDIA graphics card:
Ubuntu 98 out of 100
Ubuntu keeps Secure Boot on, so you don't need to change any settings on your PC first. Your graphics card needs one extra step after you install: a few clicks.
Pop!_OS 100 out of 100
Pop!_OS handles this graphics card best, because its NVIDIA download comes with the driver already in it.
First, you turn off Secure Boot in your PC's startup settings. GreyHaven shows you how for your PC's maker. How to turn off Secure Boot
Questions
Will this delete my files?
Not if you choose Keep Windows too: Windows, your apps and your files stay as they are, and Linux gets space next to them. GreyHaven still asks you to back up first, because changing the drive's layout is the one step that can go wrong. Replace Windows erases the drive, and GreyHaven won't let you go on until your backup checklist is done. Scanning never changes anything.
Can I go back to Windows?
Yes. You try Linux from the USB stick before installing anything; take the stick out and Windows starts as before. With Keep Windows too, you choose Windows or Linux every time your PC starts.
Will my games work?
Most single-player games do, through Proton in Steam. Some online games block Linux with their anti-cheat. GreyHaven checks the games on your PC, and you can try any game in the checker above.
Is it really free?
Yes. GreyHaven is free and open source, with no ads, no account and no paid version. Ubuntu, Linux Mint and Pop!_OS are free too.
Do I need to be technical?
No. GreyHaven is written for people who've only ever used Windows. Every step is explained in plain words with pictures, it checks your PC before each step, and your guide goes with you on your phone when your PC restarts.
