While using Unetbootin, you might encounter some common problems. Please don’t worry, and we've discussed some common issues and their solutions below:

UNetbootin Can't Download The Distribution

If you are trying to download the distribution in UNetbootin but facing a problem. Don't fret, as you can use the manual method of downloading the ISO file straight from the official website for the PC and then import the file to the software using the diskimage option. Make sure you download the ISO file on your USB drive.

My USB Stick/Hard Drive Isn't Detected

If UNetbootin is not detecting your USB drive, reformat the USB drive as FAT32, and use UNetbootin again. If it still isn't showing up, use the targetdrive command line option to specify the target device to install.

Below are the command lines for different OS types.

macOS:

/Volumes/UNetbootin/unetbootin.app/Contents/MacOS/unetbootin installtype=USB targetdrive=/dev/targetdrive

You have to replace the "targetdrive" with the appropriate target disk type, such as /dev/disk2s1, /dev/disk3s1, or diskutil list.

Windows:

c:\users\geza\downloads\unetbootin-windows-647.exe installtype=USB targetdrive=targetdriveletter\

Make sure to replace "targetdriveletter" with the appropriate Windows drive letter: D:\, E:\, or F:\

Linux:

unetbootin installtype=USB targetdrive=/targetdisk

Replace “targetdisk” with the correct drive name, i.e., /dev/sdc1, /dev/sdb. You use mount or fdisk -1 if you don't know the correct letter.

Part 6. A Quick Verdict: UNetbootin and Rufus, Which One to Choose?

Apart from UNetbootin, Rufus is another software that you have possibly heared about. So if you're looking for a simple and easy way to create a bootable USB drive, you can't go wrong with either Rufus or UNetbootin. Moreover, both programs are free to download and use.
