rEFInd does not detect my windows 10 file on USB

[Jusuf Velovic]

Hi guys, This is my very first time using rEFInd and i wanted to download windows 10 on my 2010 13" macbook pro.I am using the El Captian IOS. I already partitioned my SSD and formated in a FAT configuration. I also burned the windows 10 onto my USB using the terminal. I downloaded rEFInd correctly because the boot manager comes up everytime I restart my computer. My only problem is that it will not read my USB. I was following a guide on reddit where others have had success. I have tried changing ports as well as pressing ESC many times, but nothing is working. I want to know what i am doing wrong, and if you guys can help me fix this problem. I would greatly appreciate it you could explain in simple terms because I am still new to this.
Thank You in advance.

Without knowing how you prepared your USB drive, I can't offer much in the way of suggestions. The one that springs to mind is to hold the Option (or Alt) key as you power on your Mac and hear the startup chime. This should bring up the Mac's built-in boot manager, which sometimes detects removable media better than rEFInd does.

Also, be very careful about installation mode (BIOS/CSM/legacy vs. EFI). Windows 8 and later often work better in EFI mode than in BIOS mode, and if you don't understand how hybrid MBRs work and how to boot in one mode or the other, you could easily end up creating a lot of problems for yourself.

Hi Roderick I first formatted my usb in disk utlitly and i picked the MS-DOS(FAT) option. Then to burn the iso (that i got from microsoft) i used the code on terminal

diskutil list
obtained the /dev/(identifer) for the flash drive itself, not its partition
diskutil unmountDisk /dev/(identifer)
sudo dd if=/path/to/.iso of=/dev/r(identifer) bs=1m
After installing i typed diskutil eject /dev/(identifer)
after i did that i removed my USB then inserted back in to see if i burned it correctly.
I hope I was clear.

I'm not an expert on Microsoft tools, but I'm pretty sure that using dd to copy the .iso file to a USB flash drive is not a suitable way to prepare a Windows installation medium. I'm pretty sure that Rufus can do this, but I don't know about other tools. (I checked UNetbootin's page and didn't see any mention of Windows being supported, for instance.)
