Dear friends

following error.
unable o find any devices of the type needed for this installation type would you like to manually select your driver or use a driver disk?

one more thing we are not able to install upgrade version like fc8, fc9 or fc10.
because our real time server runs on same centos5.

please give some suggestions.

please advice me.

If it's a very recent laptop, it may be an issue with the integrated SATA HD controller being in AHCI mode.
I would try entering the BIOS/Setup utility on the laptop and verifying whether or not this is an option... if so, try setting it to "IDE" instead of AHCI, then retry the installation.

I ran into this on some recent AMD-chipset-based HP laptops.

Also, which version of CentOS 5 are you using to install? CentOS 5.4 was released just recently, and might prove to be more compatible with its newer kernel and drivers.

Hope this helps.

Live-cd...

Is there a working OS on this laptop?

Try to download and boot a linux live-cd. I would suggest you try KNOPPIX. If the live-cd boots and finds the HDD, you can use commands, including lsmod" to see how it mounts and is configured by linux.

If the live-cd does not boot with the HDD, try the chestcodes. Perhaps there is a problem with the SATA modules, perhaps the BIOS doesn't care for linux.

Some Dell laptops require "noscsi" or nowhatever it is that they stall at when attempting to boot and function.

As the previous post suggests, the if the BIOS is set to AHCI, CentOS may want a driver for the SATA HDD before it recognizes the HDD as a device.
