I've been trying several times to burn an ISO file to my USB, even with Unetbootin, on Ubuntu it doesn't seem to work at all, how come when I download the software that it suggests me to use, and it doesn't works how to fix that issue?

Even if I try to reboot my pc it gives errors that it doesn't reads the USB?

By default this is how it's made and look like:

FAT = Maximum file size is 2 GB.

FAT32 = Maximum file size is 4 GB.

NTFS = File size limited only by size of volume.

As you can see this is the support of the file/image size that supported by each system/partition table.

So, if you're planning on using files larger than 4GB it is recommended to use NTFS nowadays. How to format a USB or external drive?

  • I'm not sure a installation USB should be NTFS... I was told to do it FAT 32. – Tim Jun 08 '15 at 20:45
  • well @Tim actually try to burn Win7 .iso Ultimate which is about 7.5-8.xGB in size? Some time ago my friend asked me to install Win7 on his pc so when I tried to burn it with Fat32 I spent lot of time trying to till then when I decided to go back to the website I downloaded it from and in noticements I saw a tutorial how to burn it which suggested to format usb to ntfs ;) – JoKeR Jun 08 '15 at 20:52
  • That is why they recommend a 16GB USB drive for 7.5-8.xGB ISO files. The limitation is a single continuous file, not the size of the partition. FAT32 supports up to 16TB partition. As long as no file in the ISO file is over 4GB, leaving it at FAT32 does not hurt at all. http://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits – Terrance Jun 08 '15 at 20:55
  • Yes @Terrance that's what I stated in my answer if the file is over 4GB that's what happened in my case. It was a mod of Win7 which contained such a huge file it was just compressed this way into one big .exe and some additional stuff/utilities. ;) – JoKeR Jun 08 '15 at 21:03
  • @JoKeR WOW! That is a big file. That's crazy that they would do that. Most people are not going to have a mod of Win 7 that contains files that large. But you my friend are definitely correct. – Terrance Jun 08 '15 at 21:05
  • The content of this answer is indeed correct, but I don't understand from what you deduce that the problem is a big file within the ISO. – kos Jun 08 '15 at 21:11
  • I just wrote what occured in my situation and what I did to solve it... probably there are alternative solutions in the OP case like you suggested using dd that can do the trick. – JoKeR Jun 08 '15 at 21:17
