Installing Qubes from USB to a USB using rufus

I have an 8gb USB stick that has been flashed with the Qubes ISO using rufus. I used the NTFS file system when flashing instead of the default FAT32 option that was available to me on rufus. Should I have used the FAT32 default instead of NTFS. I have also formatted the USB i will be installing Qubes on to NTFS. Will this cause me any problems or should I have stuck with the defaults? Thank you.
