On kernel 4.11.7-200.fc25.x86_64

I'm having problem with copying windows 10 installation files to pendrive formatted in GPT with one fat32 partition only. When I copy files, usually it stops around 5% (in space) to go and doesn't proceed further. I used two pendrives (4GB and 8GB) and it always fails. Any clues?

Using dd works just fine, but I can't use it with this iso.

fat32 won't copy files greater than 4GB. is the file bigger than that? is so, redo pendrive to use ntfs instead.

I don't think that's the issue here since you're copying single files, so none should be above 4GB.

How do you copy the files, and in what Environment? What's the error message? Is there any SELinux warning or crash infomarion coming up?

Last week I successfully installed win 10 (UEFI mode) from USB stick created like that (don't remember if it was still on 4.11.6 or already 4.11.7):

  1. format pendrive with MBR (msdos)
  2. create FAT32 partition
  3. add boot flag to the partition
  4. mount current win 10 ISO
  5. use rsync in archive mode (-a) to copy files from mounted ISO

Use this command with proper paths:

rsync -av --progress mounted-iso-path mounted-fat32-partition-path

It worked when booted in UEFI mode (despite some minor issues reported by rsync), in legacy mode other approach might be necessary. Steps 1-4 you can easily perform using Gnome Disks utility (gnome-disks). With rsync you can monitor current progress (--progress) and files details (-v) in case copying gets stuck again.
