Hello, I am aware that this question is not Fedora-related per se - so, moderators feel free to close it if you consider it too irrelevant.

Background: I watered my beloved thinkpad x201, and I am maybe going to replace it with an X220. (Screen and keyboard are broken, and I am not so sure whether I still want to invest in this machine even though it ran flawlessly and still very fast).

As you can see, I am not up-to-date with my hardware and thus not familiar with all this new (U)EFI stuff. My question is if it is possible to switch from UEFI boot mode to traditional BIOS boot in order to be able to just plugin my previous HDD into the new machine and being ready to roll? Or is that not possible/recommend and should I better reinstall my OS?

As far as I know you if your UEFI bios allow you to run on legacy mode you could and so it is posible to set old drive on the machine and it should work. But Only if your bios allow it. Hope it helps.

"watered"? Spilled liquid on it? I thought they were waterproof.

@ILMostro: I was carrying it in my bag along with a bottle of water and other important papers and for whatever reason the cap of that bottle became loose (or never was fastened enough) and water flooded my bag. The bag is somewhat water resistant. So, it took me quite some time to notice it, since no water was leaking out the bag... bad day.

@aeperezt: Thanks for your comment. That's what I was looking for. I'll check if newer Thinkpad X2xx models can run legacy BIOS mode.

@Florian, I assumed your chassis and, subsequently, the laptop were "waterproof" like my ThinkPad W520. The chassis, keyboard, etc. are designed in a way that lets the liquid bypass important parts. I guess there's a limit to how long you can let it soak. :-/

I suggest instead of trying to downgrade your BIOS, change the drive's partition disklabels from MBR-type to the new GPT-type. GPT is more reliable and flexible - no more 4 primary partition limit.
