4TB HDD on bios question

My question is simple. Can 4TB HDD be seen in linux after the booting from another smaller HDD(say 500GB) on bios system? not uefi. I know in order to use larger than 2.2TB HDD, GPT has to be used.

GPT and UEFI are not really related, your disk will work fine.

It will definitely be seen, and you can likely also boot from it.

Quote:

GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk, using globally unique identifiers (GUID). Although it forms a part of the Unified Extensible Firmware Interface (UEFI) standard (Unified EFI Forum proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of master boot record (MBR) partition tables, which use 32 bits for storing logical block addresses (LBA) and size information.

As of 2010, most current operating systems support GPT. Some, including OS X and Microsoft Windows, only support booting from GPT partitions on systems with EFI firmware, but FreeBSD and most Linux distributions can boot from GPT partitions on systems with either legacy BIOS firmware interface or EFI.
