Get multiple error codes - telling I have too little space (which was true, but have cleaned up and still not working) - and telling I don't meet the requirements. Your suggested program ran a check first that told I did meet the requirements, so this is also just bullsh*t.
And yes. I am sure I have 23h2. 100%. The suggested solutions on any pages does not work. I resign.
I think I figured out the reason for your 24H2 installation failure with the Windows 11 Installation Assistant:
Your computer did not pass the WindowsPCHealthCheck for some reason (?), which you need to pass FIRST!

But ... then there is another option, which I used on my SECOND laptop (Lenovo) successfully!
I updated Oct 18 on my old and "incompatible" Lenovo💻the big 24H2 update without any problems - it took 1 h 28 min to install the update!
It is introduced by replacing the entire operating system with a newer version and is the biggest Windows 11 update since 2021.🤔
My Lenovo has been purchased already in 2016.
I downloaded the installation file**: Win11_24H2_Finnish_x64.iso (5.29 Gb)** from the official Windows 11 download page:
Download Windows 11 (microsoft.com) (3rd installation option)
So … I downloaded the "virtual disk" or *.iso file (press the downloaded *.iso file with the right mouse button and then select "open in application" and then select "Resource management" and then click SETUP) and install from it - **everything succeeded perfectly!**😁👍
Yes older non compliant hardware which would run 23h2 upgrade fine to 24h2 with the "server method". It's a toggle to avoid the compliance test. Still have two 2011/12 running on it. Saying that ther server toggle doesn't help with the compliant hardware which are proving difficult. Suspect in the Insider programme the software was given a good working over on old hardware, you wouldn't play with it on your best hardware. Why it loads better unless the second boot security tests are less strict with less compliant hardware. Some of the posts you see have turned off the higher level of security but don't know whether that is what did it or not. Suspect why they get success. I kept on the track of trying to find the rogue driver than downgrading security.
On two fully compliant laptops one loaded straight up with the assistant the other plus 9 weeks after the memory integrity pointed to the driver that was failing the second boot. Once removed went straight in. We all pulled a chair up when it finally went past 75%.
