So basically I've been trying to install windows 7 on a 3tb drive with limiting it to 2.2tb. So far I've been unsuccessful.
I've managed to use DISKPART to convert the drive to GPT but once I go through setup it seems to revert it to MBR and limit it to 2.2tb.
I've also tried using diskpart to convert it to GPT and then trying to create a new partition on it before installing but I just get an error message saying I can't, followed by the drive being split up into MBR partitions again.
I was told that Windows setup reverts to BIOS instead of UEFI and that I should override the boot drive and select my dvd drive with an UEFI logo beside it, but I can't find the option to do this in the bios.
Any help would be appreciated. Thanks.
