Welcome to TenForums @shaun51

Usually a failed upgrade like that is due to an incompatible driver in the current Windows, or a 3rd-party AV that's not cooperating with Setup. Were there any error codes reported? That usually helps identify the cause.

One workaround is to uninstall (or at least turn off) any non-MS AV. It may also help if you boot to Safe Mode before trying to run the upgrade.

ok thanks will try both of them and let you now if it works

The error code is important.. it will alert to the phase in which it breaks.

See here Troubleshoot Windows 10 upgrade errors - Windows IT Pro | Microsoft Docs

ok will right error code down if it happens again also just tried in safe mode and got this error cant do upgrade in safe mode

I don't think safe mode is a good installation environment... it's for recovery - rather isolate the problem first. Having said that Win 7 drivers are a problem compared to Win8...so upgrading the offending driver in that case may be an alternative.

ok i tried again and got this error
windows can not install required files error code 0x8007025D
