Hi,
A lap-top with two OSes: WindowsXP and Debian/Linux R4.0 Ecth. Under
Debian, I removed all the sub directories and files of /boot by
mistake, and want to rescue the system. The hard disk partitions of
the interest system on is
##BEGIN

and /etc/fstab:

and /etc/crypttab:

##END
where the PVs of vghome are hda8, hda10, hda11 and hda12. The PV(s) of
vgresource are hda9.
I tried to make a new installation of basic Debian/Linux system on
another hard disk and attached the hard disk which the broken system
on as a mobile hard disk (use USB line). The sub-directories and
files of /boot of the new system were copied to the corresponding
place of old one and reinstalled GRUB on the hard disk and modified
device.map and menu.1st. After doing so, boot from the hard disk, the
last screen display gives:
##BEGIN
Begin: Mounting root file system ... ...
Begin: Running /scripts/local-top ... ...
device-mapper: ioctl: 4.7.0 - ioctl (2006-06-24) initialised:

Begin: Waiting for root filesystem ... ...
Done
Check root= bootarg cat /proc/cmdline
or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/mapper/hda6_crypt does not exist. Dropping to a shell
BusyBox v1.1.3 (Debian 1:1.1.3-4) Built-in shell (ash)
Enter 'help' for a list of built-in commands
/bin/sh: can't access tty; job control turned off

##END
What should I do next? Thanks in advance!
PS:
1. Though I could access most files even those on the crypted
partitions of the broken system and now I have another new system, I
really want to rescue and use the old one.
2. After I mistakenly 'rm -r /boot' on the old system, I've tried
several rescue ways:
1). undelete: remount /dev/hda3 readonly,
# debugfs /dev/hda3
debugfs 1.40-WIP (14-Nov-2006)
/dev/hda3: Bad magic number in super-block while opening
filesystem
debugfs: lsdel
lsdel: Filesystem not open
debugfs: open /dev/hda3
/dev/hda3: Bad magic number in super-block while opening
filesystem
debugfs:
Then I gave up. And try
2). reinstall kernel using "synaptic", the machine halted at the last
minute because overheat (almost complete the kernel reinstallation.
:-( old computer, about 5 years, CPU is AMD Athlon 1800+ Mobile).
