Start up in ubuntu. Go to the terminal. And re-install your grub with the following command: sudo-grub-install /dev/sda This in the suppose that ubuntu is installed on sda (the most likely). Otherwise change this to the wright component.

I tried it, and ended up dual booting. It worked just like it did when I used to install it. Installed fine and without a hitch. Set aside some memory on a separate partition and installed it on there. Ran fine, ran into a little Wireless Networking bug but that was fixed easily.

Sounds to me like you have done a UEFI install. Windows 8.1 is not going to quietly let you use Linux next to it. If you absolutely must use Windows Boot Manager instead of Ubuntu's UEFI option, in the case that your motherboard somehow won't accept anything other than the Windows Boot Manager option, you need to edit Windows Boot Manager inside Windows by ...

You would need to create a new partition for Ubuntu to install on. You can use the partition editor GParted. http://gparted.sourceforge.net/ You can create a live cd and boot into that and then resize your hard drive to create a new partition. You can follow this step by step guide to use GParted ...

I would suggest using ReFind as your UEFI manager and discard grub altogether. I purged grub off my system and have been using ReFind to select between Windows and Ubuntu. You don't need grub because the Linux kernel itself acts like a UEFI application and can be booted without using grub. Much cleaner as I don't need grub as a middleman to boot my Ubuntu. ...

You do not have to dual boot. Ubuntu will be just fine by itself even with UEFI, you just have to keep/create a UEFI boot partition when you install it by itself.

I read a lot, watched some videos and was ready to give it a go. I put in a disk with Ubuntu 14.04, chose "Something else" to install and noticed the second choice of Replace existing OS was my second drive with Windows XP. Thinking well, Ubuntu software is probably better then me at installing and it's reading my second hard drive. What is the chance that ...

remember when dual booting on the same hard drive you risk corrupting mbr and boot sectors Id recommend installing linux on a separate drive and keeping windows some times you need windows files for certain things if you have the room and an extra drive I'd definitely dual boot.

You will need to check you windows configuration. You mos likely are using the remote gateway, you do not want to have that checked. You want to only use the VPN tunnel when you are accessing IP's on the remote network.

This looks like bug #1091464. Turn off secure boot, and you should be able to boot Windows.

So what I would do is this: Install both harddrives into your computer. Format the second harddrive for your ubuntu install while still in windows. It should just show up normally under your drives. Restart your computer and enter the bios. Disable fastboot and secure boot in the bios. Boot into ubuntu from a usb or disc. Install ubuntu under "something ...

I just did the same, but it worked perfectly. Did you move the start of the windows partition or removed or formated any of the other partitions during the ubuntu installation? If you have a windows DVD, you could let the windows dvd repair the efi boot sector. After that you can use the ubuntu live cd to install grub again. This way it should work because ...

You can just install Ubuntu on virtual box or VM workstation. or you can turn your physical windows machine into a virtual one using VM workstation and can smoothly dual boot. One other thing that you can do (but i think it's too advanced is to try booting using V Sphere and then work on multiple OSs). I hope this info helps.

You probably deleted your recovery partition during the Ubuntu installation. This can happen if you choose the "Use entire disk" option when installing. The Windows 8 recovery CD's may restore these partitions if they are branded with the OEM manufacturer of your computer (Lenovo). Unfortunately, using these restore disks will completely re-partition the ...


0

Try booting up off of the recovery CD, and that may have a installer on it. You may also be able to contact the manufacturer (Lenovo I believe, not positive, although I'm sure you know XD), and ask them for a installer (they'll probably want your serial and proof of purchase).

Yes you can use Remmina Remote desktop client Its one of many available, and you do not need 3rd party software like Team Viewer. Other apps for that that you can use on ubuntu are: Remotedesktop Client,2X Client RDP / Remote Desktop you can also use rdesktop from terminal With any of those you do not need anything installed on the windows machine


2

You can use TeamViewer: http://www.teamviewer.com/ It's very easy to install in any Operating System and very easy to connect (you just need to introduce the ID and PIN of the computer you want to control).

Install a package called "Boot Repair" FYI: Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can't boot Ubuntu after installing Windows or another Linux distribution, or when you can't boot Windows after installing Ubuntu, or when GRUB is not displayed anymore, some upgrade breaks GRUB, etc. Kindly ...

So I just now was able to successfully make my laptop a dual boot. The way I got rid of the grub rescue prompt was actually by changing my boot mode from Legacy Mode to UEFI. I did this by booting into the bios menu when I turned on my computer by pressing f2 (for me). I then scrolled over to Boot and switched this under the Boot Mode option. This got rid ...

The probability is extremly low. The Linux guest will not (be able to) run a virus designed for Windows. Thus it can't infect anything. There might be a vulnerability that affects Virtualbox that might be used to infect the host system. Can't be ruled out, but I have never heard of the like. And since this would have a very limited audience, it's not likely ...

You have Windows 8 on a UEFI capable machine and an EFI System Partition (ESP). Checking the log, everything looks fine to me and you should be able to boot the Windows Boot Manager boot option (NVRAM entry) or the default UEFI boot loader (\EFI\Boot\bootx64.efi) to successfully boot Windows. That is unless you modified the files on the ESP in the Microsoft ...

If you are not copying between them then no... Most of the viruses will not run on linux/ubuntu therefore will not infect the host OS. A better thing to do is to install calmav on ubuntu and have a good antivirus on windows.

You can't unmount a partition that your using. If you have to Ubuntu disk, pop that in and boot into the live environment (try Ubuntu without). Then open gparted, and partition your drive yow you want. Then shutdown, and insert your windows 8 install disk. Make sure you click the customize option, and choose to install it to the correct partition. When ...

You need to make some free space out of Windows 8 for Linux. For this, in Windows 8, go to Disk Management tool. In the Disk Management tool: Right click on the drive and select shrink volume.

Download Gparted at http://gparted.org/ (it is free) . If "Install Ubuntu alongside Windows is missing" u need to have a logical partition to install Ubuntu alongside. Boot with USB or CD with Gparted on it, and make the necessary changes.

Also You don't need to convert your partition to logical(That was me!!) just delete your partition(Warning: be careful all your data in this partition will be deleted) and make it as unallocated space then try to boot Ubuntu from CD/USB and follow screen instructions. If you select unallocated space partition during installation Ubuntu automatically converts ...

Frankly, I would use EasyBCD. It provides a pretty simple, handy gui and it makes configuring your bootloader a snap... Good luck, hope it helps.

Ok, I am a complete noob, but here is something that you can at least try... I am using 14.04 LTS, so it might be a slightly different process for you.

Turn off secure boot, and grub should be able to boot Windows (bug 1091464) Another bug, 384633, has the initial grub.cfg file using the wrong devices (because the install media was counted, causing the sdc to be used instead of b etc.). You may be able to fix this by first editing the grub commands (instructions at bottom of screen, changing the devices ...

Try booting into your live CD and selecting "try" instead of install. Then open a program called gparted (Click "Ubuntu button" and type in gparted). You should be able to see all the partitions currently on your hard drive. Within the installer, at one point on the screen where it asks if you want to install Ubuntu in addition to or over your old ...

Go to disk management in windows and check for that extra storage place and if not of use then format it. After that you can proceed to installation. If the problem persists please provide better insight to problem by errors prompted snaps, snapshot of the disk management from windows and fdisk command from live CD ubuntu.

Try it! Select the alongside option. The installer then will you set how much space is going to be used for Ubuntu. If it shows three partitions, you're fine. But I assume it will attempt to split up the Windows partition. If this is the case, go back and select "Something else". Now it will ask you to set up everything manually. Do the following: Delete ...

The folder is owned by a different user. Only the owner of the folder or root can change the permissions using chmod. Therefore, in my case, sudo is required as my user does not own the folder.

After searching a little bit more the solution to my problem is: In a Windows Command Prompt window launched with Administrator privileges: bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi If this is not your solution read this. I found this here.

When installing any OS on an UEFI based computer and GPT disk installation source - USB/DVD - should be booted the UEFI way. Nothing more. Ubuntu GRUB can chainload Windows on BIOS and UEFI. Windows boot manager can chainload GRUB/Ubuntu only on BIOS/MBR. BootNext utility can boot Ubuntu/Linux directly from Windows.

I wouldn't be surprised that it has to do with GRUB. Reinstall your GRUB on master drive after you instealled both OS, which forces GRUB to detect BOTH OS, and configure itself (be sure to reboot).


0

Have you attempted to reinstall GRUB from that point? In my case, when I installed Ubuntu for first time - it works, just like your end. I then installed Windows next, and it did the job. I then reinstall GRUB so that way GRUB will recapture both of Ubuntu and Windows and configure it to run on your master drive (GRUB only can be install on master ...

Boot again from your Ubuntu Live USB and open GParted. Set the boot flag to your Ubuntu partition. This will result in using GRUB2 as boot loader, which is installed on your Ubuntu's partition. When the boot flag is set to the Windows partition, it will use Windows' boot loader.

If I understand correctly, you want to install windows on a machine that already possess Ubuntu. Yes it is possible. But you will have to shrink your Ubuntu partition first in order to make some space for windows. Use gparted to shrink the partitions easily (especially if you are new). Then the windows installer should propose you an option to install ...

According to your error message, I think you didn't shutdown your Windows OS. Since your system is having dual boot OS, you need to shutdown it properly(i.e. neither hibernate nor sleep). Open your Windows OS and shutdown it properly, then again open your Ubuntu, your problem will be solved.!

Actually merely plugging in a USB memory stick or USB external hard drive permits you to use the usual Install Ubuntu options you would have with an external hard drive. The catch is that if you do this while a pre-existing installation of windows is also mounted, the boot sector of that other drive will be altered such that the computer will not be ...

I suspect I may know what is happening to your computer. It is a problem I generally try to avoid when setting up dual boot installations, but I admit, I've not yet performed a dual boot installation on a computer requiring EFI. After seeing this, I predict I'm going to hate the experience. And having said that, I suspect I have an outside the box ...
