Проблема с загрузкой

Добрый день уважаемый форум.
Столкнулся с следующей проблемой:(
"The superblock could not be read or does not describe a correct ext2 filesystem"
Имеется 2 ОС (Gentoo & Win XP)
hda1 - Win XP
hda2 - /boot
hda3 - Swap
hda4 - Root
Ниже приведен полный лог.

*Mounting proc at /proc...
*Mounting sysfs at /sys...
*Mounting /dev for udev...
*Configuring system to use udev...
* Populating /dev with device nodes...
* Setting /sbin/udev send as hotplug agent...
*Mounting devpts at /dev/pts...
*Activating (possible) swap...
*Remounting root filesystem read-only (if necessary)...
*Checking root filesystem...
fsck.ext3: No such file or directory while trying to open /dev/ROOT
The superblock could not be read or does not describe a correct ext2 filesystem.
If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else),
then superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193

*Filesystem couldn't be fixed:(
