RE: Can't boot after installation ==> ALERT! /dev/sda1 doest not exist. Dropping to a shell.
I searched the archives, but some files are not found.
Anyway, i found some others where you explained some things.
I could boot with the linux rescue cd and mount my /dev/sda1
I changed the bootlogd to YES but nothing is ever logged because the
system can never connect to SDA1, so how could it ever write something
to it ?
You also say in a message with such a fault that probably the right
modules are not loaded?
But how is that possible if the installation recognized the disk and
wrote all the files and everything and succesfully completed the

Do you have any ATA hard disks or USB disk devices (including memory
drives) attached to the system?
If so, I think you're seeing a difference in how the BIOS scans disk
devices, versus the kernel.
