No problem. That is normal when you have 2 or more operating systems. Pretty simple. Assume you have an empty disk and boot into the installation and are at the partitioning setup. create 4 partitions. Ubuntu OS needs a root of about 25Gb that can include a /home/. 25Gb is more than enough if you keep your own data outside of the system (ie. out of / and ...

I have two thoughts on this: Filesystem damage Some EFIs are highly sensitive to filesystem damage, which might make it look as if a new GRUB binary was improperly signed. This would then trigger the MokManager display you've shown. (It's not technically Shim that's showing that display, but MokManager.) In this case, you may be able to fix the problem by ...

Wait for somebody else's opinion, but here's mine. Notice this from your log: Drive: sda _____________________________________________________________________ Disk /dev/sda: 512.1 GB, 512110190592 bytes 255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / ...

Startx doesn't start a DM(desktop manager) like unity or LXDE by default. This is just a partial solution , but when you get to the screen with an ubuntu backgrounnd , right click and select open terminal. Then , in the open terminal type unity A unity desktop would appear. The only problem is that original terminal window must be kept open or unity ...

In the past, I used a UEFI shell to remove a boot option (in my case though, it was to remove the pesky Windows bootmgr), but it should be the same process. I usually use the Arch Linux installation medium to obtain a UEFI shell (I would use v2 so that you can use bcfg): https://www.archlinux.org/download/. Just boot into that disc and select the UEFI shell ...

For the most part, it doesn't matter what hard drives you put OSes on. When booting two or more Linux distros, the main thing to remember is that if the distros use different GRUB installations, only the GRUB on the first partition on the drive booted first will run. As GRUB's configuration is generally updated from the distro that installed it, every time ...

Turn secure boot off, and Windows should boot through grub. This is bug # 1091464. See https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1091464 You can add yourself to the "this bug affects 87 people" by clicking on the yellow button after the question. To continue to use secure boot, either use Rod Smith's suggestion below for a different ...

I recently made a dual boot (Windows 7, Xubuntu 16.04) on an Asus FX550JX and came across a solution to this (because I had some problems getting there). This is a bit of a "scorched earth" solution, but it worked (and that's knowing I had even managed to delete the EFI partition at some point ; and had reinstalled Ubuntu on the machine to fix the EFI). ...

this is simple, you may use easyBCD on windows and set only one boot entry for windows and then you use the disk manager from windows to format the ubuntu partitions. or, you reinstall windows and then you format the Ubuntu partitions from the disk manager in windows.

This is perfectly normal; it's happened to me on many UEFI computers. The boot*.efi entries and the Windows Boot UEFI Loader one should all boot Windows. MokManager.efi is for managing Secure Boot keys. You probably won't ever use it, but you probably want to keep it around just in case you end up needing it. The System setup entry actually boots into BIOS ...

While you can do this, it may be more convenient to use chroot jails to hold your multiple installations of Ubuntu. This has a downside that you will need to use the same kernel for all of your installations, but the upside is that you can use them at the same time, without needing to reboot, and don't need to partition your disks for the individual ...

I suggest you first install Ubuntu 14.04 and during installation make 3 partitions of 250gb ssd each disk formatted as ext4 and mount one partition as / , also format the other disk where you want to save data as /home . Then install Ubuntu 15.04 in the second partition of 250gb ssd and format it as ext4 and mount it as / and mount the other disk where you ...
