Recently, I had trouble creating a LiveUSB and asked for help here. I
was given instructions on how to create it using dd, and followed them
after correcting a slight error in the instructions. Now, I've finally
got my laptop back, and tried to use the flash drive. All that happens
is a grub> prompt. I don't know what went wrong, or how to correct it.
This is the command that I used:
dd if=f38.iso of=/dev/sdX bs=1M
And the correction was using M instead of m.

Subject: LiveUSB doesn't boot
Recently, I had trouble creating a LiveUSB and asked for help here. I was

laptop back, and tried to use the flash drive. All that happens is a grub>

It is not clear to me if things work.
To use dd, you have to unmount the drive, did you do that?
We need more information on the laptop to help.

I'm almost certain that I unmounted the drive. I think I remember
having it fail if the drive were mounted. And, before I posted on the
list, I rebooted my desktop (blowing away 42 days of uptime) and tried
to boot from the drive and got exactly the same result, so it's not my
laptop, it's either the flashdrive or the .iso. BTW, Gparted reports it
as being bootable if that matters.
5:21 p.m.
Did you enter the BIOS/UEFI boot menu and start the LiveUSB from there?

Is there any reason to think that using 1M caused the issue I'm seeing?
If not, why does it matter?

No, I don't think so. But 8M probably finishes the dd faster than 1M.
Convenience - nothing more .. :)
Again: I'd use UEFI to boot the thumb, and try another one if it fails

I'm using F25, and hope to use the drive to upgrade my desktop after
I've gotten the laptop working, and that page calls for packages that
don't exist for my box.

I'm not sure I understand: You don't try an install with the LiveUSB
but instead try to upgrade from F25 to F38 ... ?

My laptop's hard drive died, and I need to install Fedora on it. Then,
I'll use the flash drive to install F38 on my desktop, upgrading it all
the way in one step. What's hard to understand?

That would be considered an install, not an upgrade in the usual
understanding of those concepts. I had the same question when reading that.

I'm looking at it as an upgrade, because /home will be preserved, but
YMMV and clearly does in this case.

I think most people would see that as an install. You aren't keeping
anything from the old system other than /home. I've done this more than
once without losing /home (as it's on a separate partition) and always
regarded it as a fresh install.

You consider it an install, I think of it as an upgrade.

Fedora also considers it an install. From
https://docs.fedoraproject.org/en-US/fedora/latest/system-upgrade/
Automatic upgrade using dnf system upgrade
The preferred way to upgrade your system is an automatic upgrade
using the dnf system upgrade utility. For information on performing
an automatic upgrade, see link: Upgrading Fedora using the DNF
system upgrade.
Manual Reinstallation
Instead of relying on dnf system upgrade, you can reinstall the
latest version of Fedora. This involves booting the installer as if
you were performing a clean installation, letting it detect your
existing Fedora system, and overwriting the root partition while
preserving data on other partitions and volumes. The same process
can also be used to reinstall the system, if you need to do so for
any reason. For detailed information, see Manual System Upgrade or
Reinstallation.

This is the command that I used:
I don't know what the context is here, but are you sure you're booting
from the USB? If there's grub installed on the internal hard drive, but
missing partitions or something, then you'll get that.
dd if=f38.iso of=/dev/sdX bs=1M
That's good. You can mount the USB drive to verify that the files are
there.
And the correction was using M instead of m.
Shouldn't matter either way, other than probably being more efficient
with M.

The laptop has a new drive, unformatted and I'm trying to get Fedora
installed on it. My desktop has a working system on it, but if I try to
boot from the flashdrive, it fails in the same way that it does on my
laptop.

If so, why did dd fail until I used M instead of m?

Which iso image is this? Since you've renamed it, there's no indication
of what it is.

I did and it does.
I don't know why it's not working for you, unless there's something
funny with your BIOS. Have you tried both UEFI and legacy modes?
I created a boot drive using dd with the Workstation image and it worked
fine on everything I've tried, including an old mac mini which is now
running Fedora.

Sorry, I forgot the result of the earlier thread. "m" is invalid. The
two options are "M" and "MB".

I didn't rename it, that's the generic name used in the example I was
given. The .iso I'm using is Fedora-Xfce-Live-x86_64-38-1.6.iso
I tested that specific iso and it also worked with no problems in a
laptop and desktop with BIOS boot and the mac mini with EFI boot.
Do you have another USB drive you can try?

Di you checksum the iso? Also, try using a rocky/ubuntu .iso to
see if the problem is in your USB drive or image.

I downloaded a new copy and tried to verify it but was unable to because
some of the options needed by the commands weren't available in F25 and
the instructions were in several places, making them very hard to
follow. I think I'm going to try downloading Xubuntu and seeing if that
works. If so, I can use that to download, verify and burn a proper
Fedora .iso and overwrite Ubuntu with it. Thanx for the suggestion!

I don't know what the download page looks like but there is often an
associated file named something like md5sum and a long string of hex
characters.
If you execute md5sum file.iso you should get a match to that string.
Of course you'd use whatever sum checker that matches. There are many,
such as sha224sum, sha256sum, sha384sum, sha512sum, md5sum, etc.

The instructions have you creating and checking a sha256sum file, but
the command that's supposed to create that file fails because the file
doesn't already exist.

You don't create the checksum file. There's a link to download it.

I created a boot drive using dd with the Workstation image and it worked
fine on everything I've tried, including an old mac mini which is now
running Fedora.
As I posted earlier, I tried it on both my laptop and my desktop and got
the same results. It's hard to get into the laptop's BIOS if the
drive's inserted, and if it isn't, any attempt to leave just opens it up
again. I've sent a request to the OEM for email help on getting past
this, but I don't expect a response until tomorrow at least.
