openmandriva can't boot the iso image from my flash drive

If you are talking about installing then do not use NTFS that makes no sense. The only file system types recommended are the default ext4, plus btrfs, f2fs, or xfs.

If you want to have an ntfs partiton mounted at boot you will need to use Manual Partitioning, select that partition, select ntfs from the file system list, and if you want you can label it but that is optional. I think that should work anyway. I do not use ntfs.

If you run in to problems be aware of these articles. Including this one which you may want to read before installing:
