+==== Grub problem - Statrup freezes in Bootmenu ====
+If there has been an error with the computer for some reason, Grub is setup to ask the user to select which operating system it should load. The problem is a usb-keyboard is not recognised so it is impossible to start the OS. Rebooting does not help, the error will still remain.
+=== Solution ===
+<note important>this solution assumes that you are running Ubuntu</note>
+Take out the Compactflash card, and mount it with a cardreader on your own computer.
+Open a terminal and navigate to the folder
+  /media/[user]/51e13800-d7fd-4da3-82ba-6442e5c08ca4/boot/grub
+[user] should be replaced with the username you are using. For example
+  /media/claes/51e13800-d7fd-4da3-82ba-6442e5c08ca4/boot/grub
+Now run the following command to edit the grub configuration
+  sudo gedit grub.cfg
+you can use any editor you like instead of gedit.
+Go to line 44 and change the line
+  set timeout=-1
+to
+  set timeout=0
+If it is not line 44 find this in the file
+<code>
+if [ "${recordfail}" = 1 ]; then
+  set timeout=-1
+else
+  set timeout=8
+fi
+</code>
+change it to this
+<code>
+if [ "${recordfail}" = 1 ]; then
+  set timeout=0
+else
+  set timeout=8
+fi
+</code>
+Save the file, put the card back in the computer and start it again.
+<note warning>Remeber to change the settings back again once the computer is started</note>
