Thanks for choosing Microsoft Community.
Sorry, the information you provided is incomplete. I still need some specific details.
- What is the "adobe 3rd Gen system" you describe? Is it a special device?
- Your present situation is that installing Windows in NTSF format at Legacy boot and the screen appears blank, but it will be no problem with MBR boot, right?
- Has UEFI-started system been installed on this device now? but you still need to use Legacy boot, right?
Generally speaking, legacy is a boot way that should be adapted to the partition format of MBR. NTFS partition format is the corresponding UEFI boot, if your computer has a system installed before, your system is probably a combination of UEFI boot and NTFS partition format.
In Legacy boot, NTFS boot can install the system normally, but the reason shall not be the system that the white screen causes the system cannot be installed under MBR boot
Based on your partition type has become a NTFS, so you may need to contact your computer manufacturer to modify your hard disk partition type.
