What should I do to make an existing CentOS (5.4) disc boot up on a new computer? I just made on CentOS 5.3 installation on that machine, so I know the hardware is compatible. Would it be enough to boot with a DVD in rescue mode, or boot with another hd, and install grub? - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi

I did almost the same last weekend. Installed a new system for a friend on a virtual machine (using qemu) using a new disk and put the disk in his (old) machine (the machine wasn't available to me at the time of install) after installation. If it doesn't boot (normally because the disk numbering is different) you can use a rescue DVD and grub to fix things (probably grub-install and maybe /etc/fstab for the /boot filesystem). Is the old hd using LVM and/or labels for filesystems ? Regards, Michel

Kudzo takes care of the rest.Then you have been lucky. :-) For me, the startup stopped already before the CentOS splash screen. I guess something was wrong with the initrd. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi
