Windows 11 Upgrade Process Issue

Some months ago I uppgraded my W10 system to W11 on my Desktop using one of the methods for updating even if the PC did not meet all Microsofts requirement. I can't remember now which method I used {I got it from Youtube) Everything was fine but then a couple of weeks back I started to get problems when trying to access various sites when I would get the timeout message. I tried various ways of curing this but all to no avail and over time the number of errors I received increased. I then began to get unrelated errors with Steam which kept saying it needed an Internet connection despite the fact that the Desktop was connected. I then make a huge mistake in playing around with the W11 install to such an extent that the system reverted back to W10 and trying the upgrade again failed, Rather foolishly I played around with my system where W11 had been installed and now I have no access to Windows. I have created a bootable W11 disk but when I try to use it I get a message that the sytem has deteced a previous upgrade attempt and no matter what I do I can't get passed it. I want to be able to boot into Windows to check my drives etc as the W11 install process had been reporting that W1 could not be installed on any of my drives. I am assuming this is something I did. I am just hoping the data on my spare drives is still in tact. Be grateful if you could provide me with a way out . Thanks

If you want to perform a clean installation instead, click No.webpCelery · Jan 1, 2026 at 12:34 PM

    Hi Chris,

    If your PC is not Windows 11 compatible

    why are you trying to force it?

    I would create a USB with Windows 10

    and clean install that.

    Good suggestion but with support withdrawn looked a good option and it worked well until it didn't

    If I go "back" to W10 I still have the issue with message displayed or is there a way around it, what would I need to do?

    Do a clean install.

    If you see the message again click Yes.

    This morning I played around again with my settings. I tried a new W10 install but when rebooting got the message there was no system.

    I then looked at the Boot Menu in my BIOS and selected what I thought looked like the right partition. To my surprise Windows started to install although the screens were nothing like what I have seen in the past.

    Eventually the system rebooted and I now have W10 Pro running but it seems strange and I am not sure which partition is being used to boot from. I seem to have lost quite a few of my files, which is annoying and I have MS Money 2004 running but none of the data files will open which is the most annoying of all and will take be a long time to get back to normal.

    The drive setup as shown by Macrium Reflect is below but which one will the system boot from??

    I am also still getting timeout errors not only on my desktop but also on a new laptop I bought to use in recovery. This disproved that it is a hardware problem and is something I need to resolve as it is frustrating not knowing if a site will open.

    I feel I should be happy but I have worries it will not be stable. For example XBOX doesn't work. I am going to hibernate the system for a couple of days but I will have to do a reboot at sometime.
