Title: grub-install recheck
Post by: ananix on July 02, 2014, 11:29:42 AM

Hello im making an install script and to begin with it was working fine but now it says "Could not find device for /boot: Not found or not a block device" when trying to install boot record with grub-install.
I have tried to go back a few versions of my image, and tried to see if it was changes to system or script but I cant seem to find any thing...
Maybe some of you have an idea of how to install a boot loader with grub-install on TCL?

here is my install procedure:

tce-load -i grub-0.97-splash.tcz
sudo mkfs.ext3 /dev/sda1
sudo rebuildfstab
sudo mount /mnt/sda1
sudo mkdir -p /mnt/sda1/boot/grub
sudo mount /mnt/sdb1
sudo cp -p /mnt/sdb1/boot/* /mnt/sda1/boot/
sudo mkdir -p /mnt/sda1/tce
sudo cp -rp /mnt/sdb1/tce /mnt/sda1/
sudo cp -p /usr/lib/grub/i386-pc/* /mnt/sda1/boot/grub/
sudo touch /mnt/sda1/boot/grub/menu.lst
sudo chmod 777 /mnt/sda1/boot/grub/menu.lst
echo 'default 0
timeout 10

' > /mnt/sda1/boot/grub/menu.lst
sudo grub-install --recheck /dev/sda

Any reason not go to grub4dos?

I stopped using the older grub long enough ago that I don't remember the details of it, but one of the reasons I switched to grub4dos was that it's so simple to install.

nope, no reason, the few TCL install guides i found where just using the grub-0.97-splash package.
grub4dos im thinking its for booting FAT filesystems?
grub2 i did not think i saw in the repo.
Do you have any hints for moving down any of those two roads to get me start?

sorry to be such a bugger, but any help with grub2 would be apreciated, im just trying to make tcl boot from a harddisk, all is okay except the boot record.

the howto in the pkg description is not really working for me im for instance missing the grub.cfg....

You have to create the grub.cfg file yourself - for example:

Code: [Select]

$ sudo vi /mnt/sdc1/grub/grub.cfg
..or create the grub.cfg with a text editor, save it and then use "sudo cp" to copy it to the correct location.

That's what I thought at first, too, but it works just as well with the ext family of file systems and others.  I have no idea why they gave it such a misleading name.

I have to confess, I -still- haven't tried out grub2.

ok ill keep that in mind, but it proved to be working with grub-0.97 after all, the recheck was misleading me from something that was already working and which i was testing wrong.
to install a grub in the master boot record all you have to do is to point at the boot directory located on your disk something like this "grub-install --root-directory=/mnt/sda1 /dev/sda"
Ofcourse after you have copied the the boot folder to /mnt/sda1
