    No Boot after Power Down - solved

    My system froze and would not allow a reboot or shut down command so I manually powered off. When I power up, it shows that it can not find multiple files like root/dev, sys, proc and says no sbin/init. It seems to default to something called busybox ash with an initramfs prompt. Typing help brings up a bunch of possible commands but I am lost. Is there a method to recover?

    The hard drive passes the bios disk test. I can boot on the CD. fdisk shows it trying to boot at the correct location, sda1. I can see the file system but it says I do not have permission to look in \boot.

    If systems seems to lock up remember the elephants. Otherwise you may corrupt data and have to run e2fsck.

    Holding down Alt and SysRq (which is the Print Screen key) while slowly typing REISUB
    R-E-I-S-U-B to force shutdown
    A good way to remember it is.

    Reboot System Even If Ultimately Broken ...LOL.

    #From liveCD so everything is unmounted,swap off if necessary, change example shown with sdb1 to your partition(s)
    # To see ext3 or ext4 partitions to use
    sudo blkid -c /dev/null -o list
    #e2fsck is used to check the ext2/ext3/ext4 family of file systems.
    sudo e2fsck -C0 -p -f -v /dev/sdb1
    #if errors:
    sudo e2fsck -f -y -v /dev/sdb1

    Initially that command returned odd "can't do" messages. Then it suggested the e2fsck without the following characters. That worked. Thanks
