Hi Miroslav, Since the error message given by Installer doesn't really say what happened we can only guess. My guess would be filesystem corruption on either source (CD) or target (HD partition). Source case: get another nightly image. In case of a hardware issue with your CD burner device, try using a USB stick instead. Target case: the brute-force attempt would be to simply re- initialize (format) the target partition. If you want to keep its contents, boot the CD to desktop mode, open a Terminal and run 'checkfs' on the target volume before trying to install. If the target disk is old you might want to use some harddisk analysis tool to see if there are any bad sectors appearing. This is likely a lossy procedure, so be sure to take backups. /Jonas.
