In the last week I've tryed a lot of installer for Debian...some Sarge CD and some installer from the luther's debiand page...all stops in different points.
Sometime at 95% of base-install ...now at the begining when the installer try to mount the ext3 partion
Perhaps it depends by my hardware....ram,hd..etc?
