Hi there,
Just trying to use the grub from Ub 10.10 boot CD and it gives me
"sudo: grub: command not found"
A post suggest to do
"sudo find / -name "*grub""
which I did but then what??
The result of that last command is
/boot/grub
/usr/sbin/update-grub
/usr/lib/grub
/usr/lib/grub-legacy/update-grub
/usr/lib/linux-boot-probes/mounted/40grub
/usr/share/grub
/usr/share/grub/default/grub
/usr/share/recovery-mode/options/grub
/var/lib/ucf/cache/:etc:default:grub
/etc/default/grub
/etc/kernel/postinst.d/zz-update-grub
/etc/kernel/postrm.d/zz-update-grub
/cdrom/boot/grub
/rofs/boot/grub
/rofs/etc/default/grub

Thanks in advance for your patient help!

So... what are you trying to do?

what are you attempting to do in grub?

to see what version is installed... here is a link to grub documentation...
https://help.ubuntu.com/community/Gr...ing%20GRUB%202

And by implication, (legacy) grub commands won't work on grub2.
More info needed.

Ubuntu 10.04 uses Grub2.

Grub2 has no shell as Grub1 so the "sudo grub" command should never work.

99% of what you want from "sudo grub" is available in Grub2 using its own sets of commands in a Bash terminal.

And 10.10 further enforces the deprecation of this command.
