How to create MBR bootable Windows USB installer from Linux?

Question

In a Windows machine I have used Rufus for creating a USB installer for Windows. How can I do the same from Linux?

I want to create a Windows USB installer (for Linux UNetbootin and many more tools work fine). For UEFI boot, simple copy pasting in FAT partition works. But I could not find solution for creating MBR bootable Windows USB.

ms-sys does the magic of writing boot record.

There's essentially a duplicate question on ServerFault, which should help you out. The whole process is pretty much the same since Windows 7: serverfault.com/questions/6714/… Also did you try whether you're not just missing the active/bootable flag for your partition?

For the record, ms-sys is actually what Rufus uses behind the scenes to install the boot records, so, yeah, you should be able to achieve the same with ms-sys on Linux...
