How to install FydeOS (ChromiumOS) the only one on the HDD (the laptop does not see the bootloader)?

Question

GRUB

Good afternoon.

1. Actually, I made a bootable flash drive using the recommended etcher .
   
2. Loaded.
   
3. Ctrl+Shift+F2
   
4. I write (as in the manual ):
   

> chronos
> lsblk
> sudo /usr/sbin/chromeos-install --dst /dev/sda
> Y

5. I restart.
The hard disk is not detected, which, apparently, indicates some kind of error in the bootloader (that is, grub).
And how could this actually be fixed?
Perhaps I'm doing something wrong?
Thanks in advance. Didn't find an answer. If it exists, please provide a link.

Answer 1

There is an example in the manual.
The lsblk command lists disk partitions.
You need to determine which one is your hard drive and which flash drive and choose zero, for example, my disk is defined as mmcblk0 - where 0 is just the root of the disk, and the flash drive is defined as sda0 and has a number of partitions of about 13.
Therefore, I write, for example, sudo /usr/sbin/chromeos-install --dst /dev/mmcblk0
Also don't forget to switch to root mode after logging in > chronos with >sudo su.
Further, at the beginning of the installation, you are asked that the data will be erased on the selected disk, confirm - y / n?
In general, there is an installation manual, but not for FydeOS, but I advise you to read
