Hi all, really appreciate what you do here. My question is relating to installing Windows 7 on an SSD. I've read a lot about the differences between the UEFI and legacy BIOS but haven't found an answer to this question. I know that UEFI mode formats a drive in GPT and legacy BIOS mode does it in MBR. My question is, can I enable AHCI for an SSD in legacy BIOS mode using an MBR boot sector? I assume I can, but I would like to make sure. Using an Asrock mobo. My second question is if I install Windows 7 this way, if I for example have a 4TB external drive, can I utilize it's full capacity if it's formatted in GPT, or does the boot drive also have to be GPT? Thank you.
