I installed a new HDD today.  I was so excited until I realized Windows 7 doesn't recognize half of it.


Options?  Install dual OS? Does Ubuntu or other distro support larger than 2TB single-disk drive or partitions?


I tried to install Windows 10 and failed.  I suppose it's not UEFI compatible?!?






System specs are as follows:

You need to ensure the partition layout is GPT and then install Win 10 to take full advantage of the disk.


This article should help you on your way.

That said most modern Linux OS's use EXT4 partitioning by default which supports up to 16TB.


There's no time like the present to change.

From looking at the specs of this computer it most likely has a legacy BIOS. A GPT formatted disk working with the old legacy BIOS as a boot disk can give problems.




According to Microsoft's Windows and GPT FAQ, no version of Windows through Windows 7 can boot from a GPT disk unless the computer uses UEFI. To boot from a GPT disk, you need a version of Windows for the Itanium CPU or Windows Vista or later on a UEFI-based system.






In addition to legacy BIOS if this disk is an advanced format disk with native 4k sectors then Windows 7 can also have issues.
