Do you have a UEFI BIOS? Determining this is a step preceding Diskpart so did you skip steps?
If so are you booting the disk as a UEFI device? With a UEFI BIOS you should try that first. But you would not convert to MBR to install to UEFI.
If you are in doubt boot into BIOS setup to look for settings for UEFI, CSM, Legacy BIOS and BIOS Boot Priority. Report back those settings as they exist now and the other choices.
We deal with these cases every day and not a one has failed to get installed if there is close cooperation.
