Hi guys, I have a doubt.

I have 2 hard drives (SATA), and in one of them I have the XP and in the other one I have the UBUNTU.

I bought new computer parts, everything new (never used before), motherboard, RAM, processor. For storage I'll be using my old hard drives.

My question (kinda of a beginner's question) is can I just put my old hard drives in my new assembled machine without reinstalling the Operational Systems? Will everything WORK fine, or do I have to reinstall the XP and the UBUNTU on each drive again?

(I used UBUNTU'S GRUB to have linux and windows in the same machine with two hard drives).

Thank you all.There's a chance that it'll boot up but it won't be very stable. I'm not sure how Linux will react to a different motherboard but Windows XP will at the very least demand that you re-activate. Its device manager will also become a huge mess with GHOST DEVICES everywhere.

however, if you reinstall Windows XP, you'll end up breaking the Linux bootloader so you might be forced to reinstall Ubuntu as well.
