[How-To] Boot Entirely from SATA

[crom]

Hi, it almost works for me, but it fails to mount the root.
Here's the layout of the data drive:

$this->bbcode_second_pass_code('', '
Device Boot Start End Blocks Id System
/dev/sdd1 2048 14848 51204 83 Linux
/dev/sdd2 14849 57686529 230686724 83 Linux
/dev/sdd3 57686530 61049645 13452464 83 Linux
')

Accourding to the output of the kernel it tries to boot from /dev/sda1, but it should be /dev/sda2 IMO:

Did I miss something, or how can I set the default boot option to sda2?

Cheers

[WarheadsSE]

That is booting from NAND.

Now that you mention it... I modified 'disk' in the script to the correct disk, here's my working directory:

I have a B04 (pink) one w/o pcie. Previously it was booting from USB. Any hints?

Edit: The disk is directly connected with a SATA cable at the moment.

Looks promising, I'll try it tomorrow.

[tilator]

By the way, previously there were told it's not possible to boot entirely from GPT sata drive.

If someone is interested in knowing how to do it, just ask. I have it working with the Silverstone DC01 here. Akitio Mycloud Mini has same hardware and I suppose the same works with it too.
