4.0 Tb drive won't boot

Thread needs solution

I cloned my 500 Gb hard drive to a 4.0 Tb Western Digital hard drive using True Image 2013, but the larger hard drive won't boot. I set the bios to boot from the larger drive and enabled UEFI booting. I formatted the larger drive as a GPT drive. I am using Windows 7 Pro. All the files are visible on the larger drive and the full capacity of the drive is recognized by Windows Explorer.

Any suggestions?

Robert,

If you cloned a MBR disk booting through traditional BIOS to a GPT disk, you most likely have a MBR disk now.
To migrate your MBR/BIOS disk to a GPT/UEFI, you can do the following:
- disconnect the computer from the internet to avoid having plenty of updates of windows slow you down,
- using diskpart, clean your bigger disk,
- install a fresh Windows on the new bigger disk making sure you let the Windows installer format the disk,
- remove your older disk, and make sure the bigger disk boots normally
- create any other partition you want on your bigger disk. Might be a good time to create a content partition separate from the C:\System partition...
- create a full disk backup of your bigger disk and keep that backup
- create a partition backup of your older disk C:\System partition. You just need the C:\ Partition
- restore the backup of the old C:\ Partition on the new disk C:\ Partition
- remove the old disk
- try to boot the computer. Most likely it will fail to boot.
- boot the computer on the Windows installation DVD, and repair the startup of the computer.
- after the computer has successfully booted on UEFI, you can put your old disk back in to move anything you didn't restore
That should work.
