I downloaded Fedora-Workstation-Live-42-1.1.x86_64.iso and followed directions to check the checksum. dd'ed the file to /dev/sdf . At the time, that was a USB adapter for an SD card. cp'ed /dev/sdf to f1.iso . cp copied more than was dd'ed, so I interupted it. cmp told me Fedora-Workstation-Live-42-1.1.x86_64.iso was an initial string of f1.iso .
When I tried to boot from the SD card, I got Trying to boot from CD-ROM Trying to boot from USB device GRUB hang
I have also tried using the boot menu. When I tell the boot menu to use the USB device, it doesn't. It just boots from the hard drive as if that was what I told it.
What is going on? What do I try next?

So you should have a good download.

Follow the directions to check the checksum against /dev/sdf (or whichever device the SD card shows up as). Or you could do "diff -sq --binary Fedora-Workstation-Live-42-1.1.x86_64.iso /dev/sdf" and let it tell you if the files are the same.

I do not understand what you are trying to do here.
When I tried to boot from the SD card, I got
[various boot failures]
Check BIOS/UEFI settings: o is it set to allow booting off of SD cards? The default setting on my laptops forbids booting off of SD cards. o are you in UEFI mode or "legacy" mode? I think F42 requires UEFI, though I could be wrong.
Then do the checks against the SD card I mentioned above.

I copied /dev/sdf so that I could compare it with F...42...iso . I literally got more than I bargained for. The first part of what I got was the same as F...42...iso .
With your diff, I got that they differ. sudo cmp ... tells me Fedora-Workstation-Live-42-1.1.x86_64.iso /dev/sdf differ: byte 32769, line 2 which implies one is not the beginning of the other, despite what I got earlier.

I'm pretty sure it is. Among other things, I have an old version of Fedora installed to an SD card.
o are you in UEFI mode or "legacy" mode? I think F42 requires UEFI, though I could be wrong.
Don't know. Is there a way to check, very preferably without rebooting? I am sooo tired of rebooting. Would that be a change from F40? That is what I have now.

My suggestion would be: - re-do the checksum verification against the download to make sure it hasn't gotten damaged in the meantime. - dd the iso to the SD card - do the checksum verification against the SD card. If this passes the copy on the card should be good. If you want to be doubly sure do the "cmp" or "diff" with the downloaded iso and the SD card - there is no reason to make a third copy of the iso.

I'm not even sure if F42 requires UEFI - I've been using UEFI for a while now so I haven't had to worry about it. I think I have a laptop that runs F40 in "legacy" mode, but it would have been an upgrade from an earlier Fedora version, F36 or even earlier.

Copying from the SD card will get you the entire size of the SD card. As long as the first part matches the iso then it's good. What kind of computer are you trying to boot on and how old? I've had issues with older devices and USB. One in particular I had to burn a DVD to install.

HP Compaq dc5800 . Bought it used. One of the stickers mentions Vista. It will boot from USB. Once upon a time, I installed F39 on an SD card using a USB adapter. It will still boot from that card and adapter. The internal drive and the F39 SD card both have dos partitioning. F42, on the other hand: hennebry@fedora:~$ sudo fdisk -l /dev/sdf GPT PMBR size mismatch (4684615 != 31116287) will be corrected by write. The backup GPT table is corrupt, but the primary appears OK, so that will be used. The backup GPT table is not on the end of the device.

I hope I do not have to resort to burning a DVD, and if I do that it works. I also have an HP EliteBook 840 G3 laptop that currently has Windows 10 and F39. I'd been hoping to install F42 on both machines the same way. The laptop has no DVD drive. Alas, I no longer have any idea how I got F39 onto the laptop. It no longer boots from USB and there is not a lot of other options.

'Tis good.

cmp reaches EOF on the file, so the SD card is good. That is different from last time. Alas, I get the same hang.

My desktop has a dos partition table. The .iso file appears have a gpt partition table. My desktop can mount the first filesystem.

That seems to imply that the solution is for me to build an install medium with a recent kernel or to wait for F43.

The 3 should be a 2.

I burned a DVD. cmp says the DVD is good. Test and boot fails. Boot without testing succeeds so far as I can tell. Not sure whether installing from it is a good idea.

The last time I installed Fedora (40, I think) I had to use the install for the headless server, the normal one (Mate spin) would not boot. The server version had a different boot scheme.

I had the same experience with F41 and the Workstation spin.
