I downloaded and installed
debian-testing-i386-netinst.iso <http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/debian-testing-i386-netinst.iso> 27-Dec-2007 05:25 175M
After installation and installing grub to mbr, I rebooted.
The system wouldn't boot. It stopped with something like "Loading...please wait"
I knew the whole system was installed, so I rebooted into a different distro to check the grub configuration.
At least on my laptop (acer aspire 3000), grub used the generic ide format (pata?). The installed system used sata.
Grub listed systems using hd0,x and hdax and after booting the system, the sda devices were used.
After making changes to grub, the system boots fine now.
