#Unetbootin 377 free download install#

So if you get that error, first think back if you accidentally deleted any of your Ubuntu files from your flash drive. After that it was all back to normal.Īlso I re-downloaded both Ubuntu and the installer just in case (but Im sure it was nothing wrong with the original downloads now). Then when it finished I noticed all of those files I had deleted.

So the problem was that I had just highlighted and moved those two files back on the usb stick and it didn't go back to working right until I went back in and ran the installer like before (I used the Universal USB one) and it will go through the whole renaming the disk and everything.

(I only deleted it all because I had tried to install two different OS on the same USB and it was messing up my Ubuntu and I couldnt figure out what wasn't Ubuntu so I deleted everything.) Well I figured out it was because I had deleted everything from my flash drive and just moved the ISO and the installer back to the drive. I had this same issue on my USB flash drive. I know this is super late but just in case anyone else has the same problem. So make sure you have both files in the syslinux folder. cfg) in the syslinux folder at root of the device. The system looks for these two files (.bin &. Open the USB installation media, then rename the following: isolinux –> syslinux (folder) So when you try to burn and boot a CD/DVD iso from USB, it cannot recognize the type of boot medium as it will not have syslinux folder it will simply give Boot failure : No DEFAULT or UI configuration directive found!. Whereas the iso images that are intended to be run from USB has all the files required for boot in the syslinux folder. Generally the iso image that are intended to be burned and booted from CD/DVD has all the files required for boot in the isolinux folder.
