I've had a disaster on my home network server; the partition table on the disk containing / has become corrupted, and testdisk has not enabled me to recover the table. If anyone can help with this I should be grateful. However, that is not what I am writing about. I've installed a substitute box - and HP MicroServer - which by a miracle has CentOS-5.6 installed on it. Now I'm wondering what is the best way to install CentOS-6, given that there is no CD/DVD driver on this machine. I have access to the internet, so I can download the CD/DVD . I know I could install through a USB stick; I'm just wondering if there is a more direct route. I should look this up, but I'm rather weary after installing dovecot, httpd, etc, and thought I'd take a short cut by asking you gurus. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

When using testdisk I found the best practise is NOT to attempt to rewrite anything. Extracting as many files as possible off the bad partition should be the priority. -- With best regards, Paul.

This would, of course, require another 'nix system on the LAN running DHCP, TFTP, and NFS B) boot a USB stick with the Netinstall image, and point it at a http URL of the centos repository, which could be either a local mirror or one on the internet somewhere as long as your internet is reasonably fast and stable. I'd suggest doing a bare minimal install this way, then adding other stuff post-install with yum. -- john r pierce N 37, W 122 santa cruz ca mid-left coast

You could also add the setup grub entry to your grub, and put the ISO files on a local HD (that will not be overwritten). JD
