I installed Ubuntu a month ago, then decided to reinstall Windows 10. I tried copying files from ISO to a FAT32 formatted USB flash drive, making this with woeusb and unetbootin, adding flags. After making the Windows bootable USB with unetbootin, the USB flash drive starts, but the bootloader don't see windows files/gives only default option.

If your pc is UEFI, you should:

  1. Create NTFS filesystem on USB's first (and single) partition,

  2. Set the partition type to 'Microsoft Basic Data`

  3. Copy all files from ISO to USB

  4. Reboot, enter boot menu and select USB's first partition to boot into

People usually make mistake of creating FAT32 filesystem, but in most cases it does not work since windows ISO include a bigger file than the size supported by FAT32

If your pc is not UEFI, you should use WoeUSB tool to create bootable `Windows Pendrive'
