Windows 10 and 11 (tried both) install always fails, all partitions were deleted without backing up, tried multiple times, need help please

Question

I did a clean install of windows 10 on my lenovo laptop. After deleting all partitions, the installation process fails before reaching 100%. Sometimes 81%, other times it fails earlier in the installation process (example 52%, 60%, etc.)

A little window pops up and says "Windows installation failed". I tried multiple times. I tried both windows 10 and 11, rewrote the media creation tool, retried Rufus tool more than once, and I tried ventoy more than once too.

What's wrong with my laptop? Should I just buy new laptop/pc?

• jsotola: Should I just buy new labtop/pc. this is asking for an opinion, so it is not allowed ... do you have any other questions?
• Vylix: @jsotola what they're really asking is "what is wrong" and "should I buy a new laptop/PC" is their implied solution.
• Vylix: OP, have you tried using different flashdisk for installation?
• jsotola: @Vylix how can you be certain that you know what the OP is thinking?
• patkim: You might have a bad Storage (HDD/SSD). Using third-party Live Windows OS that boots off USB (no installation done) try to check the health of the storage device. As already stated above try using another USB flash drive to create installation drive and check again.

Answer 1

This sounds like a bad/failing storage drive, but, try a different installer package/device first, because that's cheaper and easier.

So, get a different USB stick and create the installer stuff on it and run that. If it works, the problem was your USB stick. If it doesn't and you get the same or similar symptoms, the problem is probably the storage drive inside your computer, and you should replace it.

You could use a tool such as Ultimate Boot CD and one of the drive checking tools on it, such as DISKINFO, to check the status of the drive to get more data and possibly confirmation that it is failing.

Answer 2

Your laptop hardware is failing. Most likely the SSD.

When Windows fails at different percentages during install (52%, 60%, 81%), that almost always means:

→ The SSD/storage drive is bad or dying.

Not the USB. Not the ISO. Not Windows 10/11. Not the installer.

This is the classic symptom of read/write errors on the drive.

tHE fix!

Replace the SSD. It’s cheap and easy on most Lenovo laptops.

After installing a new SSD, Windows will install normally.

!do NOT buy a whole new laptop.!

You only need a new SSD, not a new computer.
