I'm afraid I might have damaged my computer, something is wrong and I have no idea what might be the problem.

A week ago I was going to install Debian on my computer, I put the CD in and just hit the restart button without closing anything that was running on my computer.

Now when it comes to, I think, partitioning, everything turned red and it says that it didn't detect the hard drive or didn't detect a partition or something like that. I thought electricity might have damaged my hard drive when I hit the restart button so I bought a new one, but still the error comes. Note that I had installed Debian many times on this computer before and it had always worked until after I restarted the computer like that, the restart might have nothing to do with it though.

So this is not a problem with the Debian installer or the hard drive, so it's probably some component in my computer that is damaged , what component could it be?


-- Edit --
Though I can't detect hard drives when trying to install I CAN run a hard drive that already has an operating system on it.

you bought a new computer?

no not a new computer but a new hard disk..

anyway you must run fdisk on the new hard disks and write a partition table there.

also run dmesg to check if debian has found the new drives.
