Hello, After copying an ISO of fedora 23 x86_64 into a USB key with the dd command, everything is fine - I can boot with that USB key. However, there is one machine where I have to use nosmp so that it will boot. There is some hw problem with this issue but this machine is only for simple tests so I don't mind that it will work as a non SMP machine, So I want to change the grub of the USB disk on key (add "nosmp" to the kernel command line)
When I boot into fedora from hard disk and try to mount it, it is mounted as read-only. Also specifying "rw" and a boot options does not change it - it refuses to do so: mount /dev/sdc1 -o rw /mnt/sdc1
Failed to execute operation: Access denied.
Any ideas if there is anything I can do make this USB read-write ? or is there a way to perapare Live Fedora USB key so that it could be mounted from the Hard Disk as read-write ?
Regards, Kevin

Hi, Thanks, but this does not seem to solve the problem. Once I put the live on part 1, as suggested, it will be written as read only. And the grub.conf is there, so it seems that again I will not be able to write to it as part 1 is read only. Or am I wrong ?

Hi,
'loop' mount iso, change grub.config, save as new iso, install to usb.
Thanks for the advice, but this seems not to work:
$mount -o loop /work/down/setup/Fedora-Live-Workstation-x86_64-21-5.iso /mnt/loop mount: /dev/loop0 is write-protected, mounting read-only
then unmounting and mounting with "rw" option fails:
mount -o loop,rw /work/down/setup/Fedora-Live-Workstation-x86_64-21-5.iso /mnt/loop Still Again: mount: /dev/loop0 is write-protected, mounting read-only
So obviously I cannot make any change to the mounted images.
Any idea how can I get rid of the "write protect" of the iso?

The ISO9660 format is read-only. See the other replies in this thread on how to make a writeable USB drive using the ISO file.

Here's an idea. Mount the r/o iso. Make a copy of it. cd to the copy. The copy will still have the original permissions but they are changeable. Make your changes and save it as an iso (not sure how you'd do that).

To use the "mount" command, you usually do need to be root. However, at least in Gnome, you can right-click an ISO file and open it or mount it as a user.

You do not need to be root to use the mkisofs command. But really, this is the most difficult method anyway.

*but* ever one needs to be 'root' user when editing files owned by 'root, as is case of loop mounting an iso and editing boot.conf, which is main of this thread.

As has already been mentioned several times, you can't edit a file on an ISO image even if you are root. However, you can mount an ISO image as a regular user using the Gnome disk image mounter application. But again, this is the wrong way to be solving the original problem in the first place.

Ok, I read that page, what's your point? You still can't modify an ISO file. You have to copy it and make a new ISO file. Good luck getting that new file to actually be bootable.

your above post shows that _you_ are stuck in a 'loop'. 8-)
howto modify an iso has been questioned many times on this list, so many in fact that it shows that those who ask would rather ask than spend a minute or two doing a web search.

What would that mean? Normally, you are overwriting the hard drive, so where would you put the installer files? Do you know of any other distro that has this option?
Even though there is no "official" way, it is still possible to do it and it's not that hard depending on the initial state of your hard drive.

I think he means extracting the .iso to one partition and using it to install Fedora on the rest of the drive (or even on a different drive) while not reformatting that partition. I'm not sure why he wants to do this, but it does look like it should be possible.

===> i believe you 2 are speculating too much as to op's intent.
op states that he can boot on other boxen, but not the one. nothing about install from live.
as has been written in many post on most all linux support list, a live boot is a great way to test boxen to see if hardware is compatible with intended version, which is in part what op found out with boxen that he did have a hardware problem and he need to disable "smp" because it is a "non SMP machine".
as such, to test rest of hardware, he has to get past cpu problem.
such is not to guess his actual. it is only to comment as to why one might wish to boot a boxen with a live operating system.

That sort of thing used to be possible. It was one method that those people remotely administrating a headless server used to update an installation. They can't walk into a server farm on the other side of the world, and insert media. The update has to be done from what's probably the only drive in the box.

You can easily update an installation remotely. That's what fedup and its dnf equivalent are for. Doing an initial install that way is quite a different story.

Exactly.
I'm not sure why he wants to do this, but it does look like it should be possible.
Because it seems to me to cut out one step in a fairly onerous process. At the moment I download the ISO to /dev/sda9 (or something like that), and then install it on a USB stick, which in my case seems to take an average of 2 or 3 attempts, and then install the OS from the stick.
The basic assumption seems to be that most people will burn a CD or DVD. Is that true any more? It is years since I burned a CD, and in fact several machines I have don't have a CD/DVD drive.
I normally use the LiveUSB Creator to get a live OS on a USB stick. But as I said, this usually takes me a couple of tries, eg because the USB stick is not in the correct state. (I've found that Windows offers the most reliable way of preparing the USB stick.)
Personally, I have several partitions that have nothing to do with Fedora, eg for photos or Windows, and that is where I download the ISO.

OK, make that "aren't for a RedHat based distro" if you prefer. I do know, from experience, that LiveUSB Creator won't let you make a bootable flash drive from an Ubuntu-based .iso.

unetbootin is frequently the cause of problems creating USB install media on Fedora, historically. It's one of the examples Fedora QA uses for how NOT to create installation media. It's also not supported. One of the biggest problems with unetbootin has been properly creating media that works on Macs and computers with UEFI firmware, not just ones with BIOS firmware.
dd is the most reliable, but also not the most obvious or user friendly. While it exists on all Linux distros, and OS X, it doesn't exist by default on Windows. One of the changes for Fedora 24 that's expected is Fedora Media Writer for Windows (rewrite and rename of Live USB Creator) and it will use block copy, and is expected to be more reliable.

Use livecd-iso-to-disk. It's easy, just make sure you use the --format option the first time. I've made a lot of boot flash drives this way and they always work.
The basic assumption seems to be that most people will burn a CD or DVD. Is that true any more? It is years since I burned a CD, and in fact several machines I have don't have a CD/DVD drive.
I think there's an expectation now that people won't be burning it to CD or DVD. That's why the size limits on the live images have been relaxed.

See above. Make sure you --format first so the drive is in the right state for booting.

If that is the expectation, surely it would be more logical to provide something that could be installed directly on a USB stick? Or is that impossible?

All ISOs provided by the Fedora Project, for all products and spins, can be directly written to a USB. The x86_64 versions in particular are capable of booting Macs, and computers with either UEFI or BIOS firmware when directly written to the stick with a block copy (i.e. dd) or when burned to optical media.

Way back when I had to use slow CD-ROMs to install, or not-as-slow DVDs, I found it quicker to copy installation info (ISO or expanded tree) to a partition on a drive, boot the simpler network install disc (probably could have avoided that, but was convenient enough for me), but run the rest of the install from the hard drive. I just kept one partition spare, and didn't include it as part of the install.
The installer never used to block use of an entire drive, or any drive, for that matter.

Slightly OT, and no help to the OP, but it seems extraordinary to me that there is no official way of installing Fedora from the hard disk.

You still can do that as long as you extract the ISO file. It's just if you try to directly use an ISO file that the hard drive is removed from the list. Feel free to file a bug on anaconda if that's a problem for you.

You can always add it at boot time, but you are wanting it to be permanent?
When I boot into fedora from hard disk and try to mount it, it is mounted as read-only. Also specifying "rw" and a boot options does not change it - it refuses to do so: mount /dev/sdc1 -o rw /mnt/sdc1
Failed to execute operation: Access denied.
The ISO CD format is read-only and that's what you wrote to the USB drive. Use livecd-iso-to-disk to put the contents of the ISO file on the USB. Then you can not only edit the boot files, but you can also use the rest of the storage space on the drive.

Any ideas if there is anything I can do make this USB read-write ? or is there a way to perapare Live Fedora USB key so that it could be mounted from the Hard Disk as read-write ?
Install livecd-tools and use livecd-iso-to-disk to make the stick. If you use --reset-mbr --efi --format and point it at the whole device, all data on the stick is lost, but it'll create a BIOS+UEFI bootable stick. All files will be on FAT32 which is read writable, including either grub.cfg (used on UEFI) or syslinux.conf (used on BIOS). When you dd the image to the USB stick, it retains the ISO's format of iso9660 which isn't a writable format.
