Booting old server with GPT disk

vn flag

I have an old HP proliant server with regular BIOS.

I'm planning to replace the 1TB system disk with a 4TB in it since the old DOS based partition table only supports 2TB I planning to put GPT and install Debian on it.

Will the server be able to boot with regular BIOS from such a disks?

Thats not a question if the server will be able to see the disks because I have 10TB and other large disks in other slots where I use the disks as raw for VMs so thats not an issue.

If NOT is there still a workaround to be able to utilize the remaining space on the disk?

For example I create the regular DOS MBR for the first 2TB (the system will surely boot and work) and somehow utilize the rest of the space after it booted?

GPT boot devices should run smoothly with a legacy bios as long as you use linux, see also https://www.linux.com/training-tutorials/using-new-guid-partition-table-linux-goodbye-ancient-mbr/

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
