Nevertheless, it is very important word that the primary partition on the exhausting drive should be a EFI System Partition (ESP). The ESP is a small partition that’s used to retailer the UEFI boot loader. The ESP should be a minimum of 100 MB in dimension, and it should be formatted with the FAT32 file system.
### UEFI Boot
In an effort to boot from a GPT partition, you have to have a UEFI-compatible motherboard. Most fashionable motherboards are UEFI-compatible, however it is very important verify your motherboard’s documentation to make sure. Upon getting confirmed that your motherboard is UEFI-compatible, you should use a bootable USB drive to put in the working system in your GPT partition. The bootable USB drive should be formatted with the FAT32 file system, and it should comprise the UEFI boot loader. Upon getting created the bootable USB drive, you may insert it into your pc and boot from it. The UEFI boot loader will load the working system from the GPT partition.
### Benefits of UEFI and GPT
There are a number of benefits to utilizing UEFI and GPT over BIOS and MBR. These benefits embody:
- Elevated flexibility and scalability
- Improved safety
- Assist for bigger storage capacities
- Extra environment friendly booting course of
In case you are planning on constructing a brand new pc, it’s extremely beneficial that you just use UEFI and GPT. These requirements provide a number of benefits over the older BIOS and MBR requirements, and they’re the way forward for computing.
