For some time back I installed Linux mint 17 on my desktop machine, which is a dell studio 540. During the installation process, I did not have any internet connection, because my wireless card needed a proprietary driver to work (fixed using fwcutter). So recently I wanted to install a newer distro kernel due to some bug fixes, using the software manager. It installs fine, but when rebooting the grub won't run the new kernel. So I thought I should check out the grub versions:

Grub version output from terminal: grub --version grub (GNU GRUB 0.97)

Grub version from the grub menu when booting into grub: GNU GRUB version 2.02-beta2-9

Why are they not the same ? Could it be a missing update, due to the lost internet connection during installing the Linux mint ? btw: I have no problem installing new kernels on my laptop, which did not need any proprietary driver for the wireless.

    Is this a dual boot machine? Is the grub from the older installation? – Anthon Nov 15 '14 at 13:37
  • Hi Anthon, no not anymore. I had dualboot before, but when installing linux mint I decided to clear the entire hard drive. So I do not have dual boot. – Nicco Nov 15 '14 at 14:19

Grub, its version you get printed on the command line, is considered legacy in many distributions. It's first in your path, that's why 0.97 is printed. The grub used in boot partition of you installation is newer. I think you should uninstall the old grub and perhaps re-install the new one. When installing new kernel, it seems that its configuration is added to the legacy and not to the new grub.
Please note, there are links inside my answer, their look is dimmed somehow

  • Hi igorepst, thank you for the answer. well when you say uninstall the old one, does that mean I have 2 versions of grub installed ? btw, lets say i get the new kernel running, do i have to fix the proprietary driver again ? cheers Nicolai – Nicco Nov 15 '14 at 16:17
  • Yes, you have 2 different versions installed, or else you would not see 0.97 and 2.02. About the driver: unfortunately I have no idea how this driver works, but it's possible that the driver won't work at all (because, say, something related was changed inside the kernel), or it will work as is or after re-install – igorepst Nov 15 '14 at 16:42
  • Ok, so i removed the 097, easily from the terminal. The confusing part is that how to reinstall the new one, I assume you mean the 2.02. I,ve seen posts on how to do that from a live cd/usb, but in this case that's not the thing. Or is it? – Nicco Nov 15 '14 at 17:15
  • First of all you may use the first link from my answer as the reference. Arch Wiki is one of the nest wikis about Linux. Second, see this. Basically, let's start with sudo grub-mkconfig -o /boot/grub/grub.cfg – igorepst Nov 15 '14 at 19:33
  • I appreciate your help igorepst, thank you. For now i decided to stay with the old kernel, since I don't want to screw up the wireless again. – Nicco Nov 17 '14 at 11:05
