UNetbootin not detecting mounted USB?

Question

UNetbootin is not detecting a mounted USB, the image below shows.

Solution 1

Just mount your drive:

 sudo mount /dev/sdb1 /mnt    

Solution 2

original answer from maxter (https://forums.linuxmint.com/viewtopic.php?t=165389)

from command line type:

sudo unetbootin installtype=USB targetdrive=/dev/sdX

unetbootin GUI will open with the selected drive already setted, also if it is ntfs formatted.

Solution 3

This is what worked for me

1. Delete partition in sdb1 in Gparted.
2. Reformat.
3. In terminal, type sudo mount /dev/sdb1 /mnt.
4. Run UNetbootin as normal.

Solution 4

Try this (worked well in my case):

1. (while Unetbootin is open and iso file mounted)
2. open GParted, go to GParted menu, select Devices and tick the path to your USB (/dev/sdb1)
3. Unetbootin should now recognize your USB drive and proceed with copying.
4. (you will perhaps need to eject and reinsert your USB before)

Solution 5

It is possible that the sequence you followed is as follows; your stick is formatted to contain a FAT32 file system.

1. You may have inserted the stick, selected your ISO, Unetbootin has detected your stick which reflects the screenshot of Unetbootin.

2. However, in the second step, you may have unmounted the stick manually or otherwise, but UNetbootim may not have refreshed

3. Now when you try to create the bootable USB, it cannot find where the stick is mounted because it has been unmounted.

Typically, I have noticed that the following steps work:

• Remove the bootable stick from the USB socket
• Launch Unetbootin, it would not show anything in the last row of fields, it would be empty.
• Now plug in the USB stick, it should detect and the contents will be automatically filled including the mount point
• Now proceed to create the bootable USB

Then remount your USB stick, if needed manually using mount -o remount /dev/sdb1. (And disable any hardware based write protection switch)

@the_Seppi mount: can't find /dev/sdb1 in /etc/fstab or /etc/mtab

Try replugging the stick. If you wiped it before, you may have to recreate its partition table (using GParted or GNU Parted)

[Karl Morrison]

@the_Seppi Updated! Also tried replugging, still not working.

@the_Seppi UnetBootin doesn't need the root privileges

[Sergiy Kolodyazhnyy]

@KarlMorrison couple of suggestions:1) replug the stick, check lsblk to find what's your usb's device name again, just in case, but most likely it didnt change 2) run sudo mount -o uid=1000 /dev/sdb1 /mnt ; your stick now should be mounted with write/read permissions to your username. Alternatively , try running it with -o umask 0000. The message you saw is probably because you didn't specify where to mount the stick ( I put /mnt there )

[Sergiy Kolodyazhnyy]

let me know if this helps

Format the usb drive as fat32 file system solve this issue.

I can confirm this bug also for Kubuntu 20.04 LTS. However, in my case sudo mount /dev/sdc1 /mnt effectively solved the problem. :-)

[Graham]

Don't know why, but this worked for me.

Doesn't work for me :(

unetbootin could not detect a /dev/sdb1 dd'ed with a Debian iso. I created a VFAT filesystem on top (mkfs.vfat /dev/sdb1) and then it was found. The resulting Debian install disk managed to boot on my old Thinkpad X201—unlike the regular dd method.

[Roland Weber]

Thanks @melissa_boiko, same problem here. Old netbook won't boot from a dd'd USB stick, unetbootin doesn't recognize the stick while it has the ISO filesystem.

[Parnab Sanyal]

Also I had to install p7zip-full as unetbootin was complaining about its absence

[ajaaskel]

Result: "Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the 'fuser' command. "

[Eric Towers]

Well, there's something that should be in the f***ing man(1) page!

[Andyc]

This did the trick for me. However I had to add the partition number in the device name: targetdrive=/dev/sdc1 and I had to manually mount the USB stick (for some reason, just inserting it didn't do it) with sudo mount /dev/sdc1 /mountpoint before calling unetbootin.
