Fedora file system questions


I wrote Fedora live to a usb stick and tried booting, but it goes to a grub prompt. I tried the set command and it worked so grub is functional. When using the ls /boot/grub, I get an unknown file system error. Is it possible Fedora uses a file system not read by grub?

No.
Did you check the iso you downloaded ?. How did you burn the image ? - I have never had a problem using dd for Fedora images.

I burned the iso using the dd command. There was nothing on the usb stick I could not recover. I tried validating the image but get this:

bob-keane@Bobs-Laptop:~$ cd Downloads
bob-keane@Bobs-Laptop:~/Downloads$ gpg --verify-files *-CHECKSUM
gpg: can't open '*-CHECKSUM': No such file or directory

bob-keane@Bobs-Laptop:~/Downloads$ ls
CHECKSUM Fedora-Workstation-Live-x86_64-25-1.3.iso
dcraw.c LibRaw-0.18.2.tar.gz
bob-keane@Bobs-Laptop:~/Downloads$

The CHECKSUM file is there and spelled correctly. Something weird with my computer I guess.

Edit: I found the typo. Here is the output from the checksum:

gpg: Signature made Fri 18 Nov 2016 09:15:52 AM EST
gpg: using RSA key 4089D8F2FDB19C98
gpg: Good signature from "Fedora 25 Primary (25) <fedora-25-primary@fedoraproject.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
Primary key fingerprint: C437 DCCD 558A 66A3 7D6F 4372 4089 D8F2 FDB1 9C98

Everything looks good.

This is what I downloaded:

https://getfedora.org/en/workstation..._64-25-1.3.iso

This is how I burned it:

dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb1.

You should burn the iso to the entire usb device, change to
Quote:
dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb
(or whatever the target device is if not /dev/sdb)

Please tell me it is not that simple, because that would be embarrassing. Out of curiosity, what is the difference between using sdb and sdb1?

sdb is the whole device, sdb1 is only one single partition in it (if there were partitions configured)

No luck.

bob-keane@Bobs-Laptop:~/Downloads$ dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb
dd: failed to open '/dev/sdb': Permission denied

I think I found another typo and tried again. I unmounted the drive, ran the dd if=iso_name of=/dev/sdb but got a no media (not sure the exact wording) error. So I ran the command using sdb1 again. No luck. When booting, I do not get a UEFI option in the menu. When selecting the usb stick, I get a no media found error.

sdb1 will never work. But you can try that.
please post exactly what have you tried and what's happened.

Here is what happens when writing to usb with the drive unmounted:

bob-keane@Bobs-Laptop:~/Downloads$ umount /dev/sdb1
umount: /dev/sdb1: No such file or directory
bob-keane@Bobs-Laptop:~/Downloads$ umount /dev/sdb
umount: /dev/sdb: not mounted
bob-keane@Bobs-Laptop:~/Downloads$ sudo dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb
dd: failed to open '/dev/sdb': No medium found
bob-keane@Bobs-Laptop:~/Downloads$ sudo dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb1

bob-keane@Bobs-Laptop:~/Downloads$

I don't have a camera to show what happens when rebooting.

When writing the drive with the usb stick mounted:

bob-keane@Bobs-Laptop:~$ cd Downloads
bob-keane@Bobs-Laptop:~/Downloads$ sudo dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb
[sudo] password for bob-keane:
dd: failed to open '/dev/sdb': No medium found
bob-keane@Bobs-Laptop:~/Downloads$ sudo dd if=Fedora-Workstation-Live-x86_64-25-1.3.iso of=/dev/sdb1
2813952+0 records in

1440743424 bytes (1.4 GB, 1.3 GiB) copied, 23.1709 s, 62.2 MB/s
bob-keane@Bobs-Laptop:~/Downloads$

Okay, I unmounted the drive, deleted the partition information and was able to write to sdb as opposed to sdb1. The disk boots up but after logging on to my wireless network, nothing happens. Clicking activities does nothing. Wired network works okay.
