Re: [Trisquel-users] Problems modifying grub

Okay, just to tell you, I haven't done this in a very long time. Also, I  
would need to look ahead of time to find a time  to do it anyways.


But yeah, it is totally doable.

Although, the modify the grub part I will remember how to do. :)

Thank you, CalmStorm. That's a kind offer. I will try to find some time to  
sit down at have another attempt (I'm currently revising for an exam, so I'm  
careful not to get too distracted by fun projects!).

[calmstorm]

its not too hard, unless your using full disk encryption with a non debian  
based system.

Like Hyperbola/Parabola.  I could help you probably walk you through it once  
if you wanted. Want me to pm you my email?

Thank you. Unfortunately, I have already tried that with no success.

Instead I have opted to reinstall without following the guide for encrypted  
/boot. I installed with encryption as I normally do, i.e. using the  
installer. The laptop boots rapidly and without issues now.


At least I know have an up and running libreboot'd X200 to use.

My grub difficulties are minimized when I run "sudo update-grub" upon  
restarting after any
change in my HDD hardware, such as adding a USB-connected hard drive or flash  
drive. That

makes the next restart uneventful.

[Trisquel-users] Problems modifying grub

[richardmillea]

Hi,


I am having some problems trying to modify grub on my X200.

This was my first time installing Libreboot. I have managed to flash  
libreboot, and have installed Debian with full encryption using the guide. I  
can manually boot and all is working well.


I am having problems understanding how to modify grub. I have been following  
the guide at Libreboot.


1)I modified the grubtest.cfg.
2)I renamed it libreboot_grub.cfg and moved it to /boot/grub

On boot:

1)I get the following:

error: disk 'ata0' not found.
error: disk 'lvm/matrix-rootvol' not found.
error: disk 'lvm/matrix-boot' not found.
Attempting to decrypt master key...
Enter passphrase for ahci0,msdos1 (alphanumeric code here):

I enter the password. There is a delay of about a minute

2)I get the following:

Slot 0 opened
error: disk 'ata0,1' not found
error: no such partition
error: disk 'ata0,2' not found

this repeats - i.e. 0,1 0,2, 0,3 and so on
--MORE-- (I have to press enter)
more of the same
error: seriel port 'com0' isn't found.
error: terminal 'serial' isn't found.
--MORE--

3) I press enter, the screen goes back to the main menu, then automatically  
start to boot. I am presented with the familiar 'Please unlock disk  
sda1_crypt:' prompt.


4) I enter the password and the laptop boots into Debian.


My guess is that I have edited the grub file incorrectly as I am able to boot  
but in an inefficient manner. I have tried to read through the information at  
Libreboot, but it is quite difficult for me to follow.


I did not that on the Libreboot guide where it says to look in the grub file  
for:

menuentry 'Load Operating System [o]' --hotkey='o' --unrestricted

My file said:
menuentry 'Load Operating System (incl. fully encrypted disks) [o]'  
--hotkey='o'


So slightly different. Perhaps I there are additional parts of the grub  
config I need to remove?


Thank you in advance for any help. I am proud of myself for getting this far  
with librebooting so I hope to get this issue fixed!
