Such read-only issues happen to me all the time when I use iso-images. What I do to fix such problems:

Note that <yoursdcard> is a device and not a partition, so for example sdc

Boot some kind of linux
Open a terminal
Find out what device your sd card is and verify it by using sudo fdisk /dev/<yoursdcard> -l or to get the device name too you could also use sudo parted /dev/<yoursdcard> -l

WARNING: The following command will destroy all data on /dev/<yoursdcard> so make sure that <yoursdcard> is the right device!!!!

Execute sudo dd if=/dev/zero of=/dev/<yoursdcard> bs=1000000 count=50
Execute sudo fdisk /dev/<yoursdcard>
Now use the command o to create a new MSDOS partition table on your sdcard, then use the n command to add a new partition and use w to write the changes to your sdcard and exit fdisk
Now use sudo mkfs -t <filesystem you want> /dev/<yoursdcard>1 to format your partition
Now your sdcard should work again
