4. In addition, change the timeout time to 3 seconds(default)

Choosing an operating system on Startup of Pc

Hi

Thanks for all the previous advice to cure the above problem but still it persists.

When I start the pc I get the option to choose an operating system with a 30 sec countdown where it then selects windows 10 (default) by itself.

This has now been happening for about 2 weeks and previously just booted straight to windows 10.

I would have thought there must be a way to return the pc to just boot to windows 10 as it did previously.

As mentioned all the suggestions previous have come back all ok with no faults.

Unfortunately the most recent advice below wont let me do it as it tells me I have to add a value of between

3 and 999. Also the Pc is already set to windows 10 as default.

Again would be grateful for help or advice

Thanks

Eddie

Hi Eddie,

Thank you for posting in Microsoft community.

We understand your concern and will certainly assist you to solve it.

The issue you face normally happens if someone had a old operating system and used it to upgrade to a newer version of it or completely install a new Operating system. Hence, follow the below steps to troubleshoot the issue.

1. Please press Windows key and R key and open the run dialog box.

2. In the Run dialog box, please type “msconfig”.

3. Enter the credentials (if needed), and there in the system configuration window, please select the
boot tab.

4. There, you will get the different Operating systems
installed in your computer.

5. Select the Operating system that you are currently using and select “set as default” option and then select the Timeout as “0” seconds.

5. Select Apply and Ok.

Please let us know if the issue got resolved or you need any further assistance.

Would again be grateful for advice

Thanks

Eddie
