It seems that Grub isnt installed any more in the boot sector of my hdd. No errors at all, just a blinking cursor.
Im downloading the Fedora 11 Live CD now, in hope that I can re-install Grub.
I also can't mount the encrypted root partition on the Fedora 10 Live CD. I write back, when I know more.
Thanks anyway for your posts
//edit: I've Ext3. When I first installed Fedora Ext4 wasnt marked as stable or was available at all. I've upgraded the system from Fedora 10 to 11 one month ago.
//edit2: fixed it by reinstalling Grub. Didnt know that Grub has such a nice shell.
