Hardy LTSP Install option failure

[bodycoach2]

One several machines I've tried, I followed the instructions:
After selecting language at startup, press F4, and select LTSP option.

I get all the way to the end where it installs the LTSP system (LTSPchroot)- and it fails on each installation. This has happened on several machines. Is there a bug, and if so, is there a workaround? Or, am I doing something wrong (like following instructions?)

Problem fixed. MD5 checksum was okay on the first disk, and disk integrity check out fine, but LTSP chroot wouldn't install. One the second one, everything installed.

I used GnomeBaker on the second disk, instead of Brasero.
