Windows 10: Trouble installing Win 10 64 bit, MBR/BIOS. Partition needs to be GRT

The problem I'm having is that I receive the error message: Windows cannot be installed to this disk. The selected disk is not of the GPT partition style, when trying to install Windows 10 64 bit onto the current Windows 10 32 bit system.

The current state of the drive I want to install to is...

Trouble installing Win 10 64 bit, MBR/BIOS. Partition needs to be GRT

NavyLCDR, how a super star Guru like you be so WRONG.

What I wrote works as I described.
- If you have a Windows 10 32 bits installed as Legacy-MBR and you boot the Windows 10 64 bits installation drive as Legacy, and choose to install on same partition of the Windows 10 32 bits, a Windows.old folder will be created with all Windows 10 32 bits folders.
I confess that your affirmation that I was wrong put myself in doubt.
So I downloaded a Win 10 1909 32 bits iso and made a USB legacy boot able drive.
I installed Win 10 1909 32 bits on a spare drive and then I've installed Win 10 2004 64 Bits.




It did created a Windows.old folder as OP wanted (See post #5).
All this effort just to prove myself (and to others here) that I was right (and you Wrong).



I've seen that you frequently quote others post and say "You're wrong".
Not very polite to your colleagues at the Forum, and sometimes, not always, you're the wrong person.

 

Trouble installing Win 10 64 bit, MBR/BIOS. Partition needs to be GRT

So, the best thing for me to do if I want to boot using UEFI Bios I must make that change in the Bios for the system to boot using UEFI compatible option and not the Legacy Bios option and then do a clean install of Win 10 64bit in a GRT partition. But will Win 10 SETUP give to option of how to create partitions if the Drive is clean of everything or should I format it before running the Win 10 install setup??

Trouble installing Win 10 64 bit, MBR/BIOS. Partition needs to be GRT

Hi Megahertz, you are saying or should I say have proven that I could upgrade to Win 10 64 bit on to an MBR Legacy drive with Win 10 32 bit already installed and have a Windows.old folder created while doing so? I think I still need to do something different because if I attempt to do that now as my current system and drive is configured I get the message that I can only install onto a GRT partition. I just can't seem to keep straight in my mind what it is that I'm missing. I still believe there are 2 different issues with my system. I believe my SSD drive is partitioned in a way that is conflicting with how my bios is configured and how I'm booting into the OS which is preventing me from installing the Win 10 64 bit version. If that makes any sense.
