Re: Upgrade to F16 from F15 and grub doesn't have menu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



OK, got it to boot with sone instructions I found on the web:

http://techgage.com/news/repairing_a_broken_grub_2_boot-loader_on_ubuntu/

Just had to change somethings so that they looked like in my system
(devices, path to vmlinuz, etc.)

Now, how do I verify that my grub.cfg is good, and it's installed
corrctlly so that I don't have to enter all those options by hand the
next time I have to boot?

BTW, grub2-install /dev/sda works great, but grub2-probe /dev/sda
gives this error:

grub2-probe: error: cannot stat 'devtmpfs'
