[SOLVED]Setting partition boot flag using parted in NON-IN....

Not an Arch specific question I know.

I am attempting to partition my HDD using parted in non-interactive mode. The below commands partition the drive as expected, then on completing install and configuration then booting I see an error saying I do not have an EFI partition setup.

parted /dev/sda mklabel gpt
parted /dev/sda mkpart primary fat32 1MiB 500MiB
parted /dev/sda mkpart primary linux-swap 500MiB 8.5GiB
parted /dev/sda mkpart primary ext4 8.5GiB 23.5GiB
parted /dev/sda mkpart primary ext4 23.5GiB 100%

mount /dev/sda3 /mnt
mkdir /mnt/boot
mount /dev/sda1 /mnt/boot
mkdir /mnt/home
mount /dev/sda4 /mnt/home

I believe this is because the Fat32 boot partition is not flagged as boot. I am able to boot successfully when partitioning using interactive mode.

How can I set the boot flag on this partition without using interactive mode in parted? Is this even possible?

You want the set or toggle commands.

man parted

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

How can I set the boot flag on this partition without using interactive mode in parted?

The boot flag is for non-UEFI systems & msdos partition tables.

You want

# parted /dev/sda set 1 esp on

But I would recommend gdisk (or sgdisk if you want to script the partitioning) for GPT disks.

Thanks.

Why would you use sgdisk over parted?

Because {s,}gdisk is specifically for GUID partition tables and I much prefer the handling of sectors in that program — parted will only accept bytes as size units, which can be confusing.
