Changing hardware. Format needed?

post #1 of 9
Thread Starter 
Wondering if I would need to reformat (Ubuntu 11.04) if I change hardware? Will be changing CPU, Motherboard and Ram.

Typically anytime you change the mobo, the os needs to be done. Other things don't matter, unless you have a really weird distro that freaks out when number of cores change. Sometimes you can get lucky with a mobo swap, but you'll prolly run into problems.

Hope that helps!

What I'm wanting to do is install ubuntu on a vm on my current PC then mirroring it onto a usb where I can boot from on another pc?

Would that be possible without causing any driver conflicts?

you confusing windows with linux...this is one of the ways they differ. where in windows you need to reinstall with such an upgrade, with linux this is not needed.

as for your vmware question, shouldn't effect it, as drivers are contained as modules for the kernel.

as long as you're not changing 32/64 or to some crazy processor i don't think you'll have anything to worry about.

you should check your kernel config's cpu and memory settings and make sure they are still correct. idk what ubuntu puts into that, chances are it's probably not right for you already.

source based distros will want to update the compiler options and rebuild the toolchain, and then rebuild the entire system

As long as the architecture is the same (unless you're upgrading from x86 to x64), everything is going to be fine(tm)

Sorry mate, I come from the old days before usb hotplugging was in the kernel. Back then, I had tried a mobo swap and whatever I was using (slackware maybe) didn't like it. Good to see that linux has once again became more awesome than I thought possible.

Yeah, we've had it real easy since the 2.6 kernel came to be. It gets better and better every day. =)

Oh, and you can go from x86->x86_64 but not the other way around. He would then have the option to go for a 64bit OS but it isn't required.

Other than a few peripherals, even very old 2.4.x kernels should at least boot on a new mobo without incident with the basic install kernel. IOW as long as you didn't recompile to customize your kernel to specific hardware it should boot. No need to go into more detail here since so few people use 2.4.x kernels anymore except on old machines.

With modern 2.6.x stock kernels every distro, including Slackware, should have no trouble with any basic hardware. In fact Slackware comes with several kernels for specialty hardware installs such as SCSI which especially since SAS came out has become almost entirely Enterprise area.

Yes, you're right. Linux is even way more awesome than it ever was and it seems another quantum Leap is in process now with the new Xorg and support systems.
