After barely restrainin myself from throwing the PC out of the window, I created an empty partition and installed Windows in it. So you had an EFI installation of Windows at/after this point? If your answer is yes, then that was good, and we can start troubleshooting from here. After the installation, the system booted Windows by default (no GRUB ...

I have determined that this was an issue with the motherboard and not with Ubuntu Server. I had tried many settings on the BIOS to get it working (UEFI on/off fast boot on/off, secure boot on/off), but nothing worked. When I took the drive to my main computer, it worked perfectly on my newer Asus motherboard. I guess this Intel board doesn't like 4TB hard ...

Powering down in the middle of an installation because you've taken the wrong choice is always the worst decision you can take. That is like powering down your car in the middle of a busy cross-road because you took a wrong turn. (Just believe me: don't try this!) The easiest way to solve this situation is to: Enable UEFI in the BIOS and reboot. If that ...

Since you selected the option which said "This will erase your disk", the installer did just that and erased everything including your windows and then installed ubuntu.

Your desktop system is an UEFI system and your laptop is not (as I can safely assume as it was running Vista), therefore the laptop does not know how to boot this UEFI HD. You basically two options: buy an UEFI-compatible Laptop of the same brand as the laptop (otherwise the two systems will still not be compatible) Turn off UEFI Warning: this will mean ...

That sounds like a hardware failure attempting to read from your hard drive... boot-repair or another OS probably won't help at all. If it's only one or two bad sectors, then the drive might keep working for a while. If your hard drive keeps getting more / different read errors, then it could be failing & might not keep working for much longer. Could ...

Grub has installed itself on the windows boot sector so Windows cannot boot. Did you select to install it on /dev/sda1? Grub was supposed to prevent this, but if you force it manually it can happen (or maybe it's a new bug). Anyway the only way to repair it is to run bootrec /fixboot from a Windows repair prompt which you can get to using a Windows ...

When you boot up hold the SHIFT key. If Ubuntu installed correctly, GRUB should load and give you options for which OS you want to start. Try and post results.

Except that you formatted Linux partitions by error during Windows 7 installation wizard, there is no reason to think your Ubuntu files aren't there any more. I had to reinstall my Windows 7 on my dual boot machine a couple of times and faced this problem. Windows installation overwrite your MBR and put there its own code. GRUB boot directory is intact, as ...

Do not know how your got grub legacy installed to MBR, but you only have UEFI boot and data in MBR will never be used. Many vendors now modify UEFI to only boot Windows by description. So ubuntu entry does not work. But UEFI also boots hard drive entry as /EFI/Boot/bootx64.efi. So we copy grub into /EFI/Boot and rename it ot bootx64.efi and system will ...

Your laptop has two hard drives, one mechanical and one SSD. Your probably have the two operating systems installed on different drives that's why accessing the BIOS boot menu via F12 works. You have to change your boot priority in your BIOS settings to make it boot into grub permanently. Usually by pressing delete or esc at boot and change the boot order of ...

In windows, I deleted the ubuntu partition then recreated it and went from there, Now have a perfectly working dual boot! This link takes you through the steps, there are a few others around in ...
