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
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
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 ?
