Disk Utility not formatting new internal hard drive

My 2011 mac book pro recently crashed giving me a gray screen with a folder(question mark). I tried reinstalling Yosemite, with no success. I bought a 2tb seagate hard drive, placed it into my macbook, however it's in master boot record. I tried partitioning it under GUID, but it is giving me error signs, as well "waiting for disks to reappear". I am currently erasing the hard drive, I understand that a 2tb hard drive is a huge hard drive and it takes time for it to be reformatted, but it's been over 12 hours and the estimate time remaining just continues to increase. What is happening? What am I doing wrong?

Try Firmware updates for Intel-based Macs require a GUID partition scheme - Apple Support

Thanks Allan Eckert for the quick reply. However, that's something I did and it doesn't get past "waiting for disks to reappear" when I try to partition the hard drive into a GUID partition scheme. I've tried looking that up, however, I have yet to find an answer of how to fix or get past it.

Partition tab, select 1-partition, then Options button.

Tried that too, still not going past "waiting for disks to reappear"

Sounds like your brand new disk drive is no good. Return it for a replacement.

Just returned it, got the new one and same thing happened...I'm pretty confused with this right now. I used it as an external hard drive and it formatted fine. I installed Yosemite on it and ran fine as the operating system as an External Hard drive. However, as soon as I switch i put it into my laptop, it does not pick up or read. I just formatted the hard drive again and trying to install it, but now it is giving me a different error "this disk cannot be used to startup your computer yosemite". It's actually running as my internal hard drive right now and that's is what my computer is giving me.
