Windows 10 does not like dual disk

I would like to install on disk 1. Disk 1 is emtpy, disk 0 has 3TB ExFat partition, disk 3 is the Windows installer. If I try to install Windows, it has error 0x80300024. BIOS boot order has Disk 1 on top. I have rebuilt the partition table of both disks. If I have disk 0 be empty, the it installs the 50MB System partition there, but I want that on disk 1 only. I want to solve this error without physically disconnecting disk 0. If I format Disk 0 as MBR, 2TB ExFat partition, still this error happens.
Windows 10 x64
Legacy BIOS
Disk 1 NVMe 256GB MBR
What is the cause of this error?


  • @AiArtisan, Did you mean that you boot from Disk 0 to install Windows 10 to Disk 1? After installing, the system can't boot from Disk 1? Please try to convert Disk 1 to GPT, and then install again .
