Error messages ...

Hi

Sorry for my bad english (frenchy guy)! 
 
I somehow made my own bootcd from Debian.

System: CPU Athlon XP 1 Ghz, RAM 1024Mb, Debian (sid), kernel 2.6.5, vlc 0.7.2.final-1
 
Creating a bootcd, I get these warnings :
 
--- Testing CD-Image ---
--- Blanking DVD ---
* DVD±RW format utility by <[email protected]>, version 4.9.
* 4.7GB DVD+RW media detected.
- media is already formatted, lead-out is currently at
  4590208 KB which is 100.0% of total capacity.
- you have the option to re-run dvd+rw-format with:
  -lead-out  to elicit lead-out relocation for better
             DVD-ROM compatibility, data is not affected;
  -force     to enforce new format (not recommended)
             and wipe the data.

What can I do ?
 
When I leave it in ignore, my DVD+RW finish being created.
But when my computer boots from it, it stops in middle of booting and hangs.
 
Minimum of needed INODES :
 
A few seconds after, I get error messages. What should I do ?
 
touch : cannot touch `/var/log/lastlog` : read only file system.
chown : `root.utmp` : invalid user
chmod : changing permissions of `/var/log/lastlog` : Read-only file system
ln : `/var/lib/locate/locatedb` : File exists
 
 

Somebody please tell me what I should do to fix these problems.
 
Thanks in advance!
