Hi I'm a newbie and last night I installed debian Sarge (new debian installer with kernel 2.6) so I decided to avoid Grub/Lilo installation in the MBR ( dual boot system : bad past experiences) . As far as I'm concerned we can boot the system using this cd (net-installation CD) as a rescue disk, how can I do that?.

Note: I installed debian sarge in hdb1 (root ) and I 've got hdb5 as /home.

Any help appreciated.

I've never heard of a pure Debian net-install CD being used as a live-CD/recovery tool. Maybe it can, maybe it can't, but I think it can't. If you want a really good live-CD recovery tool, IMO you should burn a CD of Knoppix/Gnoppix (which is a flavor based off of Debian). That distro has truly awesome auto hardware detection and I always keep a CD or two of it around. In fact, I installed Knoppix on my laptop recently because I was too busy to worry about having to set everything up myself and everything works just fine (even the touchpad!).

Yes you can use the netinstall cd as a boot loader. Check the detailed info which is F3 if I remember correctly and I think the instruction at the boot prompt in this case is root=/dev/hdb1. If you have a look at the grub setup in /boot/grub/menu.lst setting it up is very straight forward providing you know where the files are and in most cases grub does most of the work for you during th install anyway.

Fine!!, you've got it TigerOC, that really worked. Thank you very much.
Let's start with debian...je,je,je...!!!
