réjean Posted July 20, 2015 Share Posted July 20, 2015 Hi all! I was planning to replace Manjaro with Arch tonight. I downloaded the latest version a few days ago and put it on a USB drive. I didn't go far, not even in Cfdisk ( didn't know how to start it from Arch ), then I gave up and restarted the computer but the MBR is messed up. I spent a good hour, if not more using Super Grub trying to fix the MBR, or GRUB. I cannot boot into Mint 17 which I normally use to update Grub, nor Ubuntu or OpenSUSE. I could boot into PCLinuxOS and tried "grub-install" and was told there was no error but couldn't update-grub (probably because it uses the old GRUB and not Grub 2. I haven't tried Mangeia nor Manjaro. So I decided to reinstalled Mint 17 which I had installed just a week ago because I had some problems with Mint 14 ( small graphic resolution which has nothing to do with my actual problem). The installation went well. Grub was installed to 'sda' and some 'update-grub' took place so I thought I had solved my problem or at least I hoped but not. Upon rebooting I get the following message; Verifying DMI Pool Data... error: no such device: e2f44f52-8fd1-42ca-a661-9f4ad3f86a79. Entering rescue mode grub rescue> So what can I do. I am actually replying from the live Mint 17 on the USB drive. I'll use Super-Grub and boot into PCLinuxOS or see if Mangeia can be booted or Manjaro. If you have any suggestion please let me know. Thanks! Quote Link to comment Share on other sites More sharing options...
securitybreach Posted July 20, 2015 Share Posted July 20, 2015 Well if you did not do anything on Archlinux, than the issue is not related to that. As far as cfdisk, you should follow the Beginner's Guide which will walk you through the installation. Then you follow the next guide on setting everything up which is linked to at the end of that entry. As far as this, "error: no such device: e2f44f52-8fd1-42ca-a661-9f4ad3f86a79.", it looks like the drive UUID changed or something. I would boot a livecd and run blkid as root to get the right UUID value. Here is how you reinstall Grub2 from LinuxMint: http://community.lin...torial/view/245 Hope that helps Quote Link to comment Share on other sites More sharing options...
réjean Posted July 20, 2015 Author Share Posted July 20, 2015 Couldn't boot into anything so I'm back into live Mint on USB. Has anyone seen this before? mint@mint ~ $ sudo grub-install /dev/sda grub-probe: error: failed to get canonical path of `/cow'. Installing for i386-pc platform. grub-install.real: error: failed to get canonical path of `/cow'. mint@mint ~ $ Quote Link to comment Share on other sites More sharing options...
securitybreach Posted July 20, 2015 Share Posted July 20, 2015 Perhaps: https://askubuntu.co...ers-on-live-usb That error is also covered on the link I gave in the first reply: http://community.lin...torial/view/245 Check the comments for the solution Quote Link to comment Share on other sites More sharing options...

réjean Posted July 20, 2015 Author Share Posted July 20, 2015 Thanks for the help. I'll leave it at this for tonight. Just too tired. I tried the solutions in both your 1st link and the second; mint / # grub-install --root-directory=/mnt /dev/sda grub-probe: error: cannot find a device for /boot (is /dev mounted?). Installing for i386-pc platform. grub-install.real: error: cannot find a device for /mnt/boot/grub (is /dev mounted?). mint / # grub-install --root-directory /mnt/ /dev/sda5 grub-probe: error: cannot find a device for /boot (is /dev mounted?). Installing for i386-pc platform. grub-install.real: error: cannot find a device for /mnt/boot/grub (is /dev mounted?). mint / # Quote Link to comment Share on other sites More sharing options...
V.T. Eric Layton Posted July 20, 2015 Share Posted July 20, 2015 All this missing MBR stuff reminds me of Longgone (Dale). I wonder whatever happened to him... and Kamicota (Colin) too, for that matter. 3 Quote Link to comment Share on other sites More sharing options...

Yes Kamicota was quite special, wherever he is now, or doing. 2 Quote Link to comment Share on other sites More sharing options...
