You want to run this in Terminal: sudo grub-install /dev/sda Then tell your BIOS to boot off the first hard disk.

I'm glad you fixed the problem. For future reference, you can use GRUB (or any other EFI boot manager) to switch between two versions of Windows. The way I know to do this requires planning before installing your second Windows, though: Install the first Windows normally. Boot to a Linux emergency disk (the Ubuntu installer in "try before installing" mode ...

I did "update-grub" and it solved the problem.

You should be able to dual boot. Did you leave fast boot in UEFI on. That often is the major issue, as booting Windows is required to be fast per Microsoft. And then vendors rely on Windows menu entry to get into UEFI. But when Windows does not work? And did you leave fast startup in Windows on? You may be able to directly get into UEFI with full power ...

This quesiton leaves a lot of room for opinion, but I'll lay out what I know. I run exclusively Linux for my host OS on all of my computers. I am required to run windows for certain testing situations. I have used VirtualMachines with Windows XP, Windows 7 (home-pro) and Windows 8 (Have not tried 10 yet). Ultimately how well An OS will perform in a VM will ...

If you can get a copy of Hyrens Boot you might be able to repair it using the partition wizard. Not sure where you can find a copy of it unfortunately. I got a bootable copy from a buddy of mine who mounted it on a USB. Note: To use Hyrens Boot you have to boot it from BIOS

Finally i am able to resolve this issue. There is nothing called UEFI 64 bit image for Ubuntu Desktop 15.x. It's just called plain 64 bit Ubuntu desktop ISO. Download it from here: http://www.ubuntu.com/download/desktop and then follow everything that is being mentioned out here: https://help.ubuntu.com/community/Installation/FromUSBStick

use sudo ntfsfix /dev/sdXX as sdXX is the drive name that should fix the file system permissions then try to open the drive "mounting it" I will be waiting for replay if it worked or not

Yep, there should be no issues. I dual booted 8.1 and KUbuntu 15.04 for a while and even managed to uninstall it when I didn't need it anymore to just have Windows 8.1 with no issues. All while on UEFI, I didn't try it on ATA though but both ways it should work flawlessly.

can I now reenable secure boot? Sure. From the 1st link below: It is not required to disable SecureBoot in the firmware to install Ubuntu on a Windows 8 machine. Ubuntu 12.04.2+ are SecureBoot-compatible. Any machine that ships with the recommended Microsoft Third-Party Marketplace keys in firmware will be able to boot Ubuntu under SecureBoot. If ...

So the link @Pilot6 shared worked for me. Somewhere in that long post I read that one of the problem might be that your windows partition is damaged so I checked and repaired it. After a reboot I could select to install Ubuntu alongside windows. I am writing this very post from my Ubuntu installation. Thanks a lot ! So if anyone else has this problem, ...

make sure that fast start mode in Windows is disabled. It happened with me. Disable it and shutdown and start your machine again. google about disabling this mode for more info

you need to edit the /etc/default/grub file. gksu gedit /etc/default/grub The default entry is determined by the GRUB_DEFAULT= setting in /etc/default/grub. The first "menuentry" has a value of "0". If Ubuntu is the second entry in the boot screen then set GRUB_DEFAULT=1. afterwards you need to run the command: update-grub For further information see ...

Your boot sector was probably on the Windows disc, or system reserved disc. So you need to fix this, I would recommend that you try Boot-Repair. https://help.ubuntu.com/community/Boot-Repair If this does not work, here is a more advanced way to fix your boot sector: https://help.ubuntu.com/community/BootSectorFix

I've had the same problem, so I solved that by formatting partitions in GParted before installing. Hope it will helpful for anybody!

You need to use the GRUB holdshift script. If you read the GRUB man carefully you woll notice that what you want is not achievable via standard settings. Just download the script here GRUB holdshift and follow the instructions in the readme.

If you successfully update the BIOS, result will be the same what ever way you choose, just follow the instructions. Don't worry and upgrade it from Windows. BIOS is loaded before operating system and it is an independent software. About the compatibility, if you made any changes from default BIOS setup, you should make notes, so you can make the same ...

First, a partition called SONYSYS suggests you've got a Sony. Unfortunately, many Sonys are known to have flaky EFIs, so you may be in for a fight. If the computer is new enough and you get even remotely frustrated by this, I STRONGLY urge you to return the computer to the store for a refund, then write to Sony to tell them you returned the machine because ...

To boot a Sony VAIO from a USB stick you need to: Shut down Windows. Insert an Ubuntu LiveUSB Turn the laptop on using the "ASSIST" button (not the power button). Select boot from external drive. Then follow Ubuntu installation manuals.

I'm not familiar with the utility you're using, but my suspicion is that it's creating a disk that lacks an EFI boot loader; or perhaps it includes the EFI boot loader, but something else about the disk's format is preventing your firmware from finding it. Since I'm not familiar with the tool you're using, I can't comment on it, but there are many others you ...

Window 8 "Fast Boot" feature is not actually boot at all. It is hibernation. When you install Ubuntu it is recommended to disable fast boot in Windows, because if Windows is hibernated, you can not mount Windows partitions with read/write capabilities in Ubuntu. You can enable fast boot in Windows, if you do not use NTFS partitions in Ubuntu or use them in ...

Just copy the file Unity_v5.x.ulf to drive_c/users/Public/Application Data/unity in your wine folder. If there is no such folder in that path so create. It should works!

I'm going to take some key points of your question out of order: I can't run UEFI because we'll, it literally doesn't exist on my computer anymore. I think you misunderstand what UEFI is. As described in more detail on Wikipedia, the Extensible Firmware Interface (EFI) and its version-2.x variant, the Unified EFI (UEFI) is a type of firmware that has ...

Every 64bit x86 CPU can run 32bit x86 instructions, so there is nothing special about that... AFAIK, 64bit UEFI only works with 64bit Ubuntu. I think when dual booting with Windows 8, using UEFI is the best alternative. I can't run UEFI because we'll, it literally doesn't exist on my computer anymore. How do you mean that? If you didn't do a FW ...

I'm glad you got it. As far as wubi goes (for anyone taking a look at this): Wubi will not work will not work along side Windows 8 (which I assume you were using) as long as the system is a UEFI system. For more information you can check out https://wiki.ubuntu.com/WubiGuide

Thanks, I couldn't figure out the EasyBCD thing, I think it was creating a grub boot for the SSD where Windows is installed. Instead when BIOS is booting, I select the SSD where Linux is installed and it loads, likewise I do the same for Windows.

As the_Seppi stated, using the the bootrec.exe /fixboot and /fixmbr should work. Sometimes the boot flag can be removed from the partition to boot from. Try creating a live USB of GParted and look for the following: You will notice that the boot flag is on my 2GiB boot partition. If you do have to add the boot flag back, reboot back into recovery mode for ...

The partitioning scheme can be anyway you like it.Just be sure you do not delete your Windows partitions when creating or modifying ones for Ubuntu. Paying attention will help with this.

You erased Windows. Did you do full backup of Windows? If you had also used the Something Else install option on reinstall you would not have had this problem. But auto reinstall erases system. If you have any data you want to try to recover stop using system. You will not be able to recover all data nor workable system. You can try testdisk or photorec, ...

Assuming the Boot Repair output you posted is still accurate (you note in a comment that you re-installed Ubuntu, but it's not clear if that was before or after you ran Boot Repair), it seems that the GRUB setup scripts are not detecting Windows. There are several things you can try to fix this: You should disable the Windows Fast Startup feature. This ...

If your disk uses MBR partition table, then both Windows and Linux root partitions should be in first 3 partitions on disk (if you want to use extended/logical partitions) or in first 4 partitions (but then you cannot use extended/logical partitions, because MBR is limited to max number of 4 "normal" partitions). If your disks uses GPT partition table, then ...

Your partitioning is reasonable. Order of partitions does not matter. Yes, you can. It depends on what you will install to Ubuntu /home partition. E.g. steam games are installed there. But generally it must be enough in most cases.

I don't understand why you used EasyBCD, as it's really not necessary in this case. It appears to be that you have been booted to a Grub shell. Take a look at this for how you should boot to your Linux HDD. Once you do that, run (in a terminal): sudo update-grub and it should automatically add entries to your Grub configuration.

You can install Ubuntu which ever way you prefer. Most Linux distributions including Ubuntu will use a boot loader. So when you install it there will be a menu that gives you choices to choose which OS to run. You can configure the grub file for a specific timeout period and which OS to boot from by default. Either way there will be a boot loader. However ...
