I am trying to help my brother, who is NOT computer savvy, with a problem he is having. As per the pinned suggestion in this subforum, I want to run Seagate Seatools for DOS, ideally from a bootable flash drive, to make sure his hard drive isn't hosed. (He's getting a NTFS_FILE_SYSTEM stopcode in Windows 10 when he tries to boot up.)
I found and downloaded the DOS version of Seagate Seatools but it is an ISO file. Am I correct in believing that an ISO file always implies that it needs to be burned to a DVD? Or can I put it on a flash drive and use it there "as is"? If I do that, will it be a *bootable* flash drive because that's what I need (I think). The computer won't boot so I don't have any way to get to a DOS prompt (unless the Command Prompts in the Repair Windows options will work for this purpose.)
I've done a bit of digging and know that various specific bootable flash drives can be created, such purposes as Windows 10 installation media or Memtest86 but I don't know if there's a generic way to make a flash drive bootable for *any* program I happen to need to run.
Can someone enlighten me?
