[SOLVED] USB device not bootable

Harshit_24 · 03-26-2017, 10:45 AM

I have formatted the USB using GParted. Below is the screenshot for the details.

I have tried to create the live USB with unetbootin, it is not working. It is showing the error as Operating System missing.

Before formatting from GParted, I was able to boot the live USB but now it is not working. What is wrong with the format?

Did you download a ISO file to feed into unetbootin?

Harshit_24 · 03-26-2017, 12:57 PM

I have it in my local system. I browsed form there.

I used Rufus. It formats and then lets you select your .iso

Which operating system are you using unetbootin for to put on the usb drive? They are not all supported. Most major distributions and particularly Ubuntu's are. There's a list on the unetbootin page.

Do you have another computer available on which to test to seee if it boots?

Did you try using the dd command to write the iso to the usb drive?

There's nothing wrong with the format as most usb/flash drives used for this purpose use vfat. The way I'm reading the above statements, you formatted after creating after creating the live USB which obviously would give you that error. Did you mean that you have successfully used this drive before for bootable usb systems, then formatted with GParted and again created a system with unetbootin and it now fails??

Using the Terminal

It is really simple. Go to a Terminal and type:

sudo dd if=~/Desktop/linuxmint.iso of=/dev/sdx oflag=direct bs=1048576
Where '~/Desktop/linuxmint.iso' is the name and location of your downloaded image (located at the desktop in this example) and '/dev/sdx' is the target USB drive. If your system doesn't support 'oflag=direct', you can just leave it out as it is simply intended to speed up the process a bit.

If you don't know about the target USB drive path, run this command and figure out your destination drive.

sudo fdisk -l
Warning: Make sure to set the correct device path, as this process will delete all data that was on the specified device previously!

Remember, don't include an integer for the USB drive, e.g. '/dev/sdx1', as it would refer to the existing partition on that drive and not the drive itself.

When the USB has been properly created by 'dd', there should be an output similar to this:

sudo dd if=~/Desktop/linuxmint.iso of=/dev/sdb oflag=direct bs=1048576
706+1 records in
706+1 records out
740601856 bytes (741 MB) copied, 91.7024 s, 8.1 MB/s

I don't have windows in my personal system as this software seems to work only on windows.

I am trying to boot Debian OS as I already said, I was able to boot the same system earlier, but now it is giving error. Before Unetbootin, I tried dd & I got stuck earlier. Here is the thread I created for the same.

As from the condition, it seems like after earlier creating the bootable USB using DD command & then again formatting using GParted, I am not able to make the USB bootable.

Earlier I used the same DD command, after that my USB became readonly & was not able to remove any data from it. Thats why I used GParted to again format it using FAT32.

check out this guide for Puppy Linux and make a bootable USB.

Not in this thread you didn't. Have you tried using GParted to create a new partition table before. See the link below to the GParted online Manual which explains how to do this.

Hi Harshit_24,

Your GParted image seems to be missing the boot flag for the USB drive. In any case, what I would suggest is to recreate the bootable USB using the instructions for the ISO you wish to boot .. Debian I believe you mentioned. I usually just use the dd command, but go with whatever method Debian's documentation suggests.

Cheers,

Thanks @Rickkkk, now it is working fine as I set the boot flag through GParted & again made the USB bootable, it booted successfully.

Thanks all

Good news, Harshit_24 - Cheers.
