If an ISO is bootable then it can be mounted from DVD, USB or whatever... did you try a simple search like: ISO to USB?

If the image file is a hybrid ISO which most distributions install ISO files are these days then it can be written to USB and is bootable.

The simplest method is using the dd command but it can be risky because if you are not careful you can easily destroy your OS with a typo.

There are ways to make a non hybrid ISO bootable from USB but it does not work for all distributions. The main line distribution install instructions of choice usually has the best method to create the USB.

There are a few ways to image copy an iso file to pendrive, I use dd, (see man dd for how to), just be absolutely sure you are copying to the correct disk.

Hi,

I have been burning USB start-up disc for prolonged time on Ubuntu
-> Activities -> Make Start Disk
without fail.

But following ISOs which were download about 2 days ago on CentOS sites look very strange to me.
Code:
CentOS-Stream-8-x86_64-20210406-boot.iso           07-Apr-2021 06:21           758120448
CentOS-Stream-8-x86_64-20210406-dvd1.iso           07-Apr-2021 07:06          9895411712
I can't select them to create a start-up disk. Their checksums are correct.

I have posted my problem to CentOS forum but up to now without a reply.

Regards

May want to check any of your several older threads, where you're asking about burning ISO images, such as this one from several years ago:
https://www.linuxquestions.org/quest...ck-4175419998/

You can also try putting "how to make bootable usb from iso image command line linux" into a search engine, and doing research of your own. Amazingly, this produces results like this:
https://www.howtogeek.com/414574/how...rive-in-linux/

...with pictures and complete instructions. And most distros ALSO will tell you how to create a bootable USB key on their own websites. But again...you don't tell us what distro you're trying to do this with, what version/distro of Linux you're using now (with what GUI), anything you've done/tried so far, etc.

As has been asked of you many times before, did you read the "Question Guidelines"?? You need to do basic research first, and if you can't figure it out provide details and ask a clear question (including showing your efforts) in your post. Because after *EIGHTEEN YEARS* here, you should be able to easily do such things.

Hi all,

Finally I ran
Code:
# dd if=CentOS-Stream-8-x86_64-20210406-dvd1.iso of=/dev/sdc
installing Cent0S 8 on a 64G Sandisk USB disc. The installation took 20 min to complete. It is a brand new USB disc

I don't know why "Make Start Disk" unable to work?

Now I have CentOS 8 installed on the PC

Thanks again for your advice.

Regards

Just to clarify, you used the USB to boot and install CentOS and it worked perfectly. So, above given method and command are confirmed to work. Is that correct?

Once upon time I wrote this, never failed on me, although in another thread I noticed michaelk mentioned some ISO's won't take the USB treatment with isohybrid.

If you're using a GUI, usually in a file manager and right clicking on an ISO offers "burn to disc?" Disk utilities like Brasero or K3B work too...

Yep...but as with numerous other threads from the OP, no details are provided. And we don't even know what version/distro they're trying to burn, but they do have a LOT of experience doing it, so the entire thread is a bit odd. After eighteen years, you'd think that would be something easily done...especially since most distros have instructions on how to do it on whatever website you download from.

You can just use dd as above for most distros ISO's I've seen - just make sure you target the right device though. But a lot of distros also have their own GUI based app to do it too.

PS: You don't actually "burn" an ISO image on to a USB drive, you write the ISO image to it. You only "burn it" when you are talking about optical media (eg. CDs and DVDs).
