I am struggling to install Windows 10 on an old PC (equipped with GA P35-DS3L motherboard, which has BIOS, no UEFI), from a USB stick.
- Using Microsoft Media Creation Tool, create bootable USB flash drive
- Boot to this drive (F12 at boot)
Result: Windows setup does not launch. Instead, BIOS throws error
Invalid Partition Table
My guess: the Windows tool is simply not compatible with BIOS systems, as it creates a GPT instead of a MBR.
- Download the ISO using Media Creation Tool
- Create a bootable USB drive from this ISO using Rufus (checking the "MBR" option).
Result: setup launches successfully, but I cannot get past the "partition selection" step.
Whenever I select an empty space (or a valid partition freshly created on my system HDD), I get error:
We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files.
I have also tried using diskpart to create a new primary partition (
create partition primary
format fs=ntfs quick
The error was the same when trying to install Windows on it.
My guess: the USB stick might be confusing Windows, which would see it as a HDD and try to install on it (?)
I have tried with 2 sticks (one USB 3.0 and one USB 2.0), same results.
How can I solve this?
