I cant do it. i keep getting this

cant flash kernel required files not found: guru meditation #00000025.62017712

here's what i did:
root
sudo apt-get update
apt-get install nitdroid-installer

...badabing! nitdroid installer is on my n900

on to the steps IF you dont have an SD card

sudo gainroot
mkdir /and
mount /home /and
apt-get install multiboot multiboot-kernel-power bzip2
cd /home/user/MyDocs
bzip2 -d NitDroid-0.0.8-Popov.tar.bz2
cd /and
tar xvf /home/user/MyDocs/NitDroid-0.0.8-Popov.tar
dpkg -i /home/user/MyDocs/nitdroid-kernel-2.6.28-06_final1_armel.deb

..badaboom! you'll see all this text scrolling up like when your installing on an xterm (LOL)

so i go on to type this last command:
umount /and

then it responds with the system is busy.

so i just keep going and on to this step:

root
leafpad /etc/multiboot.d/11*

and pastes this over:
ITEM_NAME="NITdroid on MMCp2 - 2.6.28.NIT.05"
ITEM_KERNEL=2.6.28.NIT.05
ITEM_MODULES=ext3 fat vfat
ITEM_DEVICE=mmcblk0p5
ITEM_FSTYPE=ext3
ITEM_FSOPTIONS=rw,noatime,errors=remount-ro,commit=3
EOF

then i save it, restart, press 2 and get this:
cant flash kernel required files not found: guru meditation #00000025.62017712

CAN SOMEONE PLEASE EDIT WHAT I DID SO I CAN GET ANDROID TOO.
