Should be plug and go. Only exception being onboard audio-which may need ALSA reinstalled to get it happy. If you're staying with an Nvidia card you should be good.

Sorry i don't understand what your trying to say, do you mean duel booting on the same HDD? or a single HDD which is swapped between machines?

I think he means this.

You should be mostly fine plugging into another computer. There are a few things that you might have to fix, and obviously a 64 bit installation wouldn't work on a 32 bit architecture.

I have done it before. Should be fine. Only issue is you will have to fix the drivers if you are switching from nvidia to ati or visa-versa.

Great many thanks..... I was asking if the intial relay worked to coordinate the OS I don't mind changing drivers or allowing it to auto find/ fix those.. I have three old computers I wanted to restablish to give to friends and it would be much easier to diagnose problems without having to reinstall OS

This is Linux, not Windows. You don't have to "reinstall."

You might bump into issues beyond just drivers.

If for instance the installation has been done on a motherboard that recognized that specific HDD on that specific port as /dev/sda2 then it won't boot unless the new system says the same OR you jump in and change that.

Generally speaking however, in motherboards that use SATA ports, as long as you plug the HDD in port #2 for example you should always get the same device name.

You're most likely looking for a USB HDD install that won't care where it's plugged.

Something like this was true many years ago, and some old distros or some DIY ones like Gentoo or Arch may still suffer from this.

If you've installed any recent version of Ubuntu, Fedora, etc., then it identifies disks by UUID and it doesn't matter what port you plug them in, or in what sequence.

Thats a good point I hadn't thought of that. Arch has the option of going by UUID but I always pick the dev option because it's quicker.


Even if you did go by /dev when you installed, when you boot on the new system you can just edit grub temporarily by command line and then edit the menu.lst once you boot.
