Open a shell window and become root: sudo su 3. Create a directory: mkdir /x 4. You need to know which drive partition holds the target system, i.e. the Linux system you want to boot. For clarity, let’s discuss things using the shell variables $partition and$drive. An example might be: partition=/dev/sda6 ; drive=/dev/sda If you happen to know, based on experience, where the target system lives, define $partition and$drive accordingly, and skip to step 8. If you need to figure it out, proceed as follows: Get a list of disk drives: cd /dev/disk/by-label; ls -al With any luck, you will see something like this: drwxr-xr-x 2 root root 200 Mar 26 07:59 . drwxr-xr-x 6 root root 120 Mar 26 08:00 .. lrwxrwxrwx 1 root root 10 Mar 26 08:00 emu -> ../../sda9 lrwxrwxrwx 1 root root 10 Mar 26 08:00 linux-root -> ../../sda5 lrwxrwxrwx 1 root root 11 Mar 26 08:00 lnx -> ../../sda11 lrwxrwxrwx 1 root root 11 Mar 26 08:00 more -> ../../sda10 lrwxrwxrwx 1 root root 10 Mar 26 08:00 SERVICEV003 -> ../../sda1 lrwxrwxrwx 1 root root 10 Mar 26 08:00 SW_Preload -> ../../sda2 lrwxrwxrwx 1 root root 10 Mar 26 08:00 usrsrc -> ../../sda7 If necessary, you can get additional information from cfdisk /dev/sda. This has the advantage of showing the partition size, along with the partition-type for each partition. Identify which partition(s) might plausibly hold the target system’s root directory. In the example above, linux-root is almost certainly the right answer, but lnx is a semi-plausible alternative. To make sure, mount each plausible partition and take a look at it. mount /dev/sda11 /x ls -al /x/boot/vm* ls: cannot access /x/boot/vm*: No such file or directory That tells us that sda11 is definitely not the right answer. So let’s try again: umount /x # unmount previous hypothesis mount /dev/sda5 /x ls -al /x/boot/vm* -rw-r--r-- 1 root root 4275712 May 30 2013 /boot/vmlinuz-2.6.39.4 -rw-r--r-- 1 root root 4678720 Aug 25 2013 /boot/vmlinuz-3.10.9 -rw-r--r-- 1 root root 4599824 Mar 23 18:45 /boot/vmlinuz-3.11.3+ -rw-r--r-- 1 root root 4599824 Mar 23 18:43 /boot/vmlinuz-3.11.3+.old 5. When you find the desired partition, leave it mounted on the mountpoint /x. 6. Define $partition and$drive accordingly. Example: partition=/dev/sda5 drive=/dev/sda. 7. If not already mounted: mount $partition /x 8. Reinstall grub: grub-install --root-directory=/x$drive Beware: You want to install grub on the drive (e.g. /dev/sda). If you install it on the partition (e.g. /dev/sda6), the grub-install program won’t complain, but the results won’t be what you wanted.  2017-12-18 01:23:57 -0500 received badge ● Editor (source) 2017-12-18 01:20:03 -0500 answered a question video tearing in totem For me the solution was to change my compositor I switched to compton. You can get is link:here. Even without a config file it will work fine but write a config file that works for you and it will work best. 2017-12-14 14:04:08 -0500 answered a question Trouble in playing videos using VLC on fedora 27? I had the same problem and I was able to solve it by changing the video output module to x-video-output(XCB). You can do so by going to tools>preferences>All>Video>Output modules and choosing what is suitable for you then save.
