First of all hello to everyone...I've been a long-time lurker and really appreciate the knowledge I've gained from this site (among others)..it's a really great resource!

Anyways, to my dilemma:

I'm do bioinformatics for my work and long story short ended up using a desktop (Dell T1700 I believe) out of necessity as it was the only one available on short notice.. Turns out it has "only" a 1TB HDD so I went ahead and ordered a 4TB HDD to make it work for my needs (kind of time sensative data so I'm stuck with what I've got). Dell says it'll work with the motherboard so no issues there. My issue is that I want to obviously clone whats on the old drive to the new drive, but being that it is now over 2TB, I have to (as far as I can tell at this point) change file formats to GPT. However, what makes things complicated (I think), is that the computer is set up with Windows running solely on a 240 GB SSD, with Ubuntu running off both this same SSD and the 1TB HDD. I tried doing the clone with GPT format, but upon installing the new drive, I got some GRUB error before anything even booted. Now that I'm thinking about it, it obviously makes sense (I think), because the BIOS likely isn't going to recognize this new drive given the new format...is that correct? Also, the BIOS may have tried to boot from this new HDD which I obviously don't want it to do.

Does anyone have any experience working with dual booted machines and trying to upgrade secondary HDDs? I think my next course of action is to try and boot into the BIOS and see if I can get the new HDD sorted out that way..I'll have to give it a shot tomorrow...

Any input is appreciated!! Thanks


 
Solution
You can't clone MBR to GPT. They use different ways of boot on each file format. You will have to reinstall from scratch if you want to boot off the 4TB
