So, pressing the Shift Key from Starting the box *should* bring up the Grub menu. Sometimes, I've tried keeping it pressed, or just repeatedly hammering on the key from start. If you really cant get a grub menu, then you can use a live distro to fix the problem.If you dont have one they are not difficult to get - for what you want to do I'd suggest something small - slitaz, dsl,nanolinux. Boot to the live distro, mount your /boot partition and edit the grub2//grub.cfg - look for entries relating to TIMEOUT - if you have HIDDEN_TIMEOUT, delete that line. set TIMEOUT=30 Save the file. umount /mnt (or wherever you mounted boot partition) reboot -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
