GPT on BIOS system partitions scheme
Could someone using GPT on a BIOS system confirm if I got the GPT partitioning right on a BIOS system
I followed the documentation from http://www.rodsbooks.com/gdisk/
This is the out put after partitioning the HDD using Ubuntu 11.10 live CD
root@ubuntu:/home/ubuntu# gdisk /dev/sda
GPT fdisk (gdisk) version 0.6.14
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): p
Disk /dev/sda: 1465149168 sectors, 698.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 8C5F38B2-BFAB-4A48-8720-5E6BB4434046
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1465149134
Partitions will be aligned on 2048-sector boundaries
Total free space is 1058782 sectors (517.0 MiB)

================================
Partition3 will be used for /boot
partition4 - LVM over LUKS
============================
Used Fdisk to mark the first partition as boot.
root@ubuntu:/home/ubuntu# fdisk /dev/sda
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.
