Use grub instead of windows bootloader

I was hoping to not have to uninstall either, but simply removing then booting into windows 7 Home Premium CD and doing the startup repair doesn't solve the problem because the Windows startup doesn't ahve a problem at that point it is a GrubRecovery issue that you recieve ATM I am in the process of removing the grub bootloader since I don't have to worry about the Ubuntu being damaged in the process. Do you want to apply repairs and restart your computer? Reboot the computer.

Thanks for the help, I'm assuming your way would help as well I just got back into my Win7 Home Prem. I ended up googling a little more after my last response and found a way to reset the MBR in the CMD prompt from Win7 disc it was a quick type.

I still wonder if there's a way to change back to Windows bootloader without installing Ubutnu as a program in windows. If so I'd love to know in case I get rushed again and make the mistake of not installing it inside windows.

Thanks in advance for the help. This thread is locked. I then tried this, which also did not work. I then tried directly installing reFIND through debian after booting into debian with a usb flash drive of refine to try to see if I could use refind as a substitute for Grub, but that also did nothing.

TL;DR: My pc boots directly into windows instead of loading grub, and I tried every method I found to fix this, but none of them worked. Can someone help me get my pc to boot with grub?

Now, you should be able to use your new bootloader to boot Linux. While most distros add an entry to boot Windows 10 as well, you may need to do this manually to boot to Windows It happens because of the windows register windows boot loader as a default boot loader that's why you are not greeted with GRUB.

First of all create a live CD of linux. Now, turn off your computer and boot it up wit the live CD. And try to Boot Repair follow the steps form here. Please check your BIOS settings. I faced exact same issue on my HP Laptop which goes directly into Windows 10 bypassing the linux boot options. My issue was resolved by enabling legacy mode and disable secure boot option.

Please check similar options in your BIOS too. The Windows boot loader will generally boot only Windows systems. You need to tell your system to use a different boot loader if you want to boot into linux.

That should list your hard-drives and the bootable partitions. I finally fixed it by enabling secure boot, which then allowed me to select my own "trusted" efi file in my bios I selected grub. This then appeared in my boot order which I then put to the top and then turned off secure boot. This option is available to Grub and Windows boot manager, so set the windows boot delay to zero to not see the windows boot manager selection menu. Add a comment. Active Oldest Votes.

Installation media for your Windows OS. If you're upgrading from Windows 8. It's also a good idea to have it on hand for the future, so you might as well create it now. Optional, but highly recommended : A drive large enough to back up your current Windows files. Enough space on your hard drive for both operating systems, a boot partition only MB , and a linux-swap partition usually the same size as your physical RAM.

Step 1: Make a backup Back up all of your Windows files and folders that you don't want to lose. Step 2: Disable Fast Startup, and shut down your computer You'll need to be logged in as an administrator to do this. You will need 4 partitions: A boot partition. If you're doing a new installation, and you want to start everything from scratch this will wipe out all of your data , go ahead and delete all of the partitions on your drive, and then make this partition. It should be the first partition ; its format should be FAT32 ; and it should be at least MB in size.

If gparted has an option to label it, just call it boot. If there's not label option, don't worry about it. You must , however, set the "boot" and "esp" flags on this partition ; without them, the Ubuntu installer will just ignore it and use a legacy mode install, and Windows 10 will refuse to install altogether with the error "we couldn't create a new partition or locate an existing one". Or not. It seems to depend on how Windows feels that day If installing both operating systems from scratch again, this will wipe out all of your data , Microsoft says you'll need at least 20 GB for the bit OS, so this partition needs to be at least 20 GB.

You'll probably want more than that, though: I just used half of the space after the boot partition for Windows, and half of it for Ubuntu and linux-swap.

If you're going from scratch, this partition needs to be formatted as FAT Do not do this with gparted; Windows' implementation of NTFS is different than gparted's implementation, and Windows may not be able to recognize the partition. In the Windows 10 installer, you should have the option to select which partition to place Windows 10 on. If it's formatted as FAT32, Windows should be able to see it and install itself there.

If you can label this partition, label it Windows. That will make it easier for you during the Windows install. Speaking of the Windows installer- don't begin that yet. If you're doing new installations of both Ubuntu and Windows at the same time, instead of upgrading from 8 or 8. A Linux partition. Like the Windows partition, this can vary in size, but Ubuntu's website recommends at least 5 GB.

Again, you'll probably want a lot more than that. If you're upgrading instead of doing a fresh install of both operating systems, you should be able to create this partition in the new "unallocated" space shown in gparted.

Make it as big as you like but remember to leave space for a linux-swap partition if you plan on using one. It should be formatted as ext4. If installing from scratch, make your Ubuntu partition just as described above. Make sure it's formatted as ext4, ext3, or ext2. This will allow Ubuntu to use it, but keep the Windows 10 installer from recognizing it, which should cause it to default to the FAT32 partition you made in step 3, which it can read.

Optional, but recommended: a linux-swap partition. At least half the size of your physical RAM is a good start, but I recommend reading the details. Step 4: Install Ubuntu first Whether you're upgrading to Windows 10 from an existing Windows OS, or installing both Windows 10 and an Ubuntu distribution to a new or newly-repartitioned hard drive, it's a lot easier to install Ubuntu first. Step 4. Deleting the wrong thing can cause huge problems.

By default, you'll get a list of entries that looks something like this: When I first used this tool after fiddling with EasyBCD and bcdedit trying to get things to boot in the right order, I had over a hundred entries here, most of them duplicates.

If you're installing both OSes from scratch, do the same thing. Do not use the automatic installation option. Step 5: Update or install Windows second You should have an installation disk for Windows After you've disabled Fast Startup again, reboot your computer. Notes I haven't mentioned Secure Boot at all, because it should normally not affect Ubuntu's installation.
