Windows 10 reinstall gpt partition problem

[Silvia_000]

Hello,

I started to reinstall windows from USB drive (this is the first reinstal) and when I have to choose the partition there is an error:

Windows cannot be installed to this disk. The selected disk is not of the GPT partition style

I find two solutions: to create a new USB, or to delete partitions through diskpart. If I choose this option I have to format only the partition on which will install windows or all partitions. After the format the partition will be deleted or not. Should I have to create a new partitions?

Is there any option to change the settings in BIos?

Hi:

See if you can install W10 by enabling legacy mode and disabling secure boot.

See this link for the settings to change...

I'm with Probook and boot from USB. Should I follow the 3 steps or just step1?

Hi:

Yes...follow the guidance in step 1, and then in step 2, select the USB flash drive as the boot device.

You cannot change the settings back to where they were, or I don't believe windows will boot.

My menu is not like that shown in the guide.  I don't know what to choose

Hi:

You must have an older notebook that did not come from HP with W8 or newer installed.

What happens when you choose to boot from the legacy boot boot device menu after you press the F9 key?

If your notebook came with W10 from HP, then there should be an enable legacy mode/disable secure boot setting in the BIOS someplace...maybe under the advanced settings tab.

HP does not provide any manuals showing the BIOS settings in their notebooks, so I have no idea where it could be.

What is the full model number of your HP Probook?

Thank you so much for the help.

I find the settings but there is one more problem now I have 4 partitions.  on the first is the operating system and on the other - recovery files, platform guides. What do you think should I start from the beginning delete the partition and create a brand new?

You're very welcome.

If it were me, I would delete every partition, leaving just one and make sure it is set to the largest size.

When you clean install W10, the recovery partition becomes useless, so there is no point in keeping that one.

I just get rid of all of them.
