Hey guys, I've been trying to install gpt partition table with cgdisk on my laptop, damn it, I failed three times, finally switch to MBR, I'm very confused about what arch wiki sayed about it.
It says that I need to use cgdisk(or sth else) to creat a extral 1007k at begin of disk and type it to `ef02`.
First, it's not possible to use the first 1024k with cgdisk.
Second, I created a 32M bios boot partition just after the '1007k'(set it to ef02), after I intall grub, run grub_install, mkconfig, there is no error.
But after I reboot, grub cannot mount real root!!! The damn thing says /sbin/init is missing...

How can I create a right GPT table? Or theres sth wrong when I install grub?

Nobody?

Have you read this before?

Actually，I read a lot about GPT, the topic about what is GPT, why GPT is better, difference between GPT and MBR...

Yes but if you will read this pdf carefully, you will be able to create GPT without any problem.

It includes all things what you mentioned above and you are facing problem in it.

By reading, I mean Adaptation not just reading...

Hi, actually the true problem was that I create different partition for root and /usr, which made vmlinux cannot find /usr/sbin/init successfully, so I guess it's not the problem how I create partition. Thanks, fellows

Actually it is possible to use any sectors with cgdisk its just a way to tell it how to do it. It normaly skips some blocks to allign with this 4k block scheme thing.
