I can't install windows 11 on HP Victus because the disk is not formatted in NTFS

[rrponzo]

I'm trying to install Windows 11 on my HP Victus 16-r0036ns

When I have to select where to install Windows, the drive 0 partition 3 comes up with a total size of 918 GB, but the free space says 0 MB.

Below it says that Windows cannot be installed, the reason is this: Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS.

I have read that with diskpart I can do a clean but I would lose the HP_TOOLS that are in Drive 0 Partition 2.

How can I convert partition 3 to NTFS without losing the data on partition 2 (HP_TOOLS)?

@rrponzo,

What's in the HP_TOOLS partition? Was it created when you installed HP Hardware Diagnostics UEFI? You can keep it if you want to save it.

If you want to clean install Windows, you need to delete partitions 1,3 and 4. Select each of them and click "Delete." Partition 1 is EFI partition that contains boot system files. # 3 is Windows partition. I don't see Recovery partition. #4 is way too big to be Recovery partition. Whatever it is needs to be deleted. 

If you delete those three partitions, they'll turn to "Unallocated Space." Click Next to proceed the installation.

The installation setup will then create new partitions, EFI (Fat32), Windows (NTFS) and Recovery (NTFS) and install necessary files in them. When the installation is complete, you should see the HP_TOOLS partition.
