Help. I think my boot sector craped out

[Lisa Kachold]

The 240 error can happen:

a) If you are trying to mount the drive in an EXT4 on an EXT2 partition
(journaling is disabled).
b) If you have mounted in EXT4 when using grub.
*c)* If you have a ext4 root and don’t use grub2, you can obtain this
error:

EXT3-fs: sda1: couldn’t mount because of unsupported optional features (240)

Add "*rootfstype=ext4*" to the kernel line* or at the grub>  line when
specifying the initrd?

**ARE you CERTAIN you have ext4 and not ext2?

You can "fdisk -l" to see a list of disks and types.**
*

Of course, there also is:

d) Your drive journal is toast as your fsck failed.

I suggest you boot into either recovery mode or LiveDistro/Knoppix and
manually work on the drive or:

0) Boot into recovery mode and follow these instructions.
https://help.ubuntu.com/community/LiveCdRecovery

if not successful:

0) Move off or backup your data.

1) Rebuild with new distro version following recovery recommendations:

I can drop an Ubuntu Live and a knoppix tool distro into the mail for you
today?  What is your distro version exactly, please and upgrade choice?

Contact me offline with your address?
