To fix that you would
1. boot from eCS installation CD
2. press Shift+F3 to get commandline window
3. fire up LVM
4. make volumes from the partitons (needed to get the
   existent partitons visible to eCS (this is free of risk)
5. exit lvm with save

6. zip -9rS system c:\* 
   same for any other partiton
   zip and unzip are in path here!

   Now you can boot again to your system (nothing chaged yet)
   to burn the the zip's onto CD/DVD

   Thereafter you would reboot to eCS install CD and
   go on commandline window as above

call up LVM again
switch to physical view
remove any partiton as needed to get free space to recreate the new partitios
- system with minimum 500 MB in size 
  (better 2GB to get yet the required size for eCS 2.0) 
- and to get the partitons you have removed back with reduced size.

There may be no need to remove any partiton, but you have to remove at lest 2 
neighbours to get the system partiton big enough. You'simply fill the created 
gap in other seizes for the needed partitions.

When you have recreated the needed plain partitons you'll switch LVM back to 
logical view and create volumes from existent partiton

- C: should be 'compatible, bootable'
  this is important because this is the only way
  to get the system partiton bootable again
- others: 'compatible'. For now because you in
          prepare state to migrate.

exit LVM with save.

7. format C: /FS=HPFS /L
   comment. /L is needed for savety
   format the other volumes you've recreated
8: restore the data from backup
   That means: exchange the CD to the one youve
   burned with the ZIP file on to one of the
   new formatted ones to be able to replace
   the the CD with the installation CD
c:
unzip x:\path\system

So, your system is back. Do the same as above to restore the data for the other 
partitons. before shooting up the zip command you have to change the current 
directory to the root you will unzip to.

and you got you old system back without any change - except the partiton sizes.

Optionally you can boot up your old system to test that it works again - but 
you can ommit that step and continue directly with the installer. It's your 
choice.
