Hi Joachim,
I wanted to prepare a bootable iso, when my laptop runs in legacy mode, to see if there is a different behaviour of the iso on usb stick prepared on a system in uefi mode versus prepared on a system running in legacy mode, but currently a have no Fedora running in legacy mode, therefore I can currently not test this behaviour.
I booted successfully F26 Beta 1.3 from usb stick with the laptop running in legacy mode (iso prepared with F24 in EFI Mode with mediawriter, x86_64, 4.0.7, fc24), I could install F26 mediawriter on this iso, but so far I can not read the F26 Beta 1.3 located on an other partition of the same stick, to make an installation of F26 - today lack of knowledge - I will solve this (mounting 2nd partition  with the F26 file on it to get access with mediawriter to this file) possibly tomorrow.
What I have seen in running the F26 beta 1.3 iso in legacy mode, is after giving access to WIFI and doing one, two, or three other small jobs successfully, the system is blocked and I have to reboot and start again, in my feeling it's not blocked because of lack on memory.
Kind regards Joerg

Hi Joerg,

I wrote the iso with mediawriter-4.1.0-1.fc25.x86_64 in F25 onto the USB
stick, but if booted, it hangs up during "loading initrd.img".


What do you mean by "I could not prepare a F26 iso running in Legacy mode"?

So, I have no explanation why the boot fails. Perhaps an USB problem?
No problems if I write the iso with K3b to a DVD. This DVD boots
completely without failure and without hanging up.

Thank you for all your replies.

Kind regards

Joachim Backes
