When you install Windows, Windows assumes it's the only OS on the machine -- or at least it doesn't account for Linux. So, it replaces GRUB with its own boot loader. What you have to do is replace the Windows boot loader with GRUB. I've seen various instructions for replacing GRUB by mucking around with GRUB commands or some such, but to me the easiest way ...

The windows installer doesn't care about other OS in the system. So it writes own code over the master boot record. Its not a problem of windows installer, its intended.

Sony's do not boot Ubuntu, just Windows. There are several work arounds and Boot-Repair renames the Windows efi boot file to be grub/shim so system thinks it boots Windows but really boots grub. But a Windows update overwrites the Windows named shim file and you are back to square one. May be better to use one of the other work arounds. I have seen all of ...

I have Xubuntu 13.10 running on my Vaio Pro. I ran boot-repair from the LiveCD and managed to get the grub menu, though Xubuntu wouldn't boot. After some research, I discovered this page: http://www.nicksplace.com.au/2013/07/04/fedora-19-on-vaio-pro-13-ssd-issues/ Its no secret that the Vaio Pro comes with a very nice SSD. The 128GB version is a ...

As it turns out on further experimentation, the problem was that I had not yet installed the official graphics drivers for Windows 7 after the initial install. As far as I can tell, the handoff from GRUB to Windows 7 screws up the use of the very basic default graphic drivers to display. But, as it turns out, if I did anything that would result in the ...

First, the bios_grub flag in parted or GParted is a way to identify a BIOS Boot Partition. GRUB 2 uses this partition to hold part of its boot code when the computer boots in BIOS mode. It's normally about 1MiB in size, although it can be smaller in some cases. Most importantly, if Boot Repair re-ran the GRUB installer after you set the bios_grub flag on ...

Boot-Repair worked for me. It's very very easy to use graphical application, you do not need to use the command line, you only have to click a button :) All the available repair options are described in the Ubuntu documentation and there is a separate page explaining how to start Boot-Repair (by creating a bootable disk or installing it in an existing ...

I had this same problem with my HP Pavilion g6 when trying to dual boot Ubuntu 12.04.3 LTS and Windows 8. That is, even after "successfully" running Boot-Repair, I still had the notebook booting directly into Windows 8. If I pressed F9 before the HP symbol showed up, I was able to get into a Boot Menu (HP's menu? I don't know...) and from there, to select ...

Your Boot Repair output shows a GRUB configuration for Windows as on a BIOS-based computer, but you seem to be running in EFI mode. That's the root source of your problem. One solution is to create a manual GRUB stanza, like this: menuentry "Windows 8" { insmod part_gpt insmod chain set root='(hd0,gpt2)' chainloader ...

Boot repair won't delete anything on your hard drive. It will just repair boot issues by making GRUB the default bootloader in the Master Boot Record

Installing Grub manually is fairly simple, and once you get it, there shouldn't be anything keeping you from dual-booting successfully. First, boot the computer up off of your standard Ubuntu installation disk. You should be using the same version (e.g. 13.04) and the same architechture (e.g. amd64, 64-Bit) as your currently installed Ubuntu. If you need ...
