Install grub windows bootloader

Just put others, so we manually changed it to Windows 8. Now then, by default, the way that GRUB addresses disk drives and partitions are different from the way that the kernel does,. For our RHEL installation here, we have got hd0, 2. Well, first of all, we need parentheses. Then we add the HD, which is short for hard disk. Then the first number here is the device number as per the BIOS, so 0 being the first disk device on the system.

And remember GRUB is a proper computer system. It starts counting at 0, not at 1. Then we need a comma, and then we give it the partition number. We would use hd0 to address the MBR on the first device, hd1 to address the MBR or the volume boot record on the second device. So, what we have got here is the third partition on the first hard drive on the system,.

Now, if the kernel were addressing this device, it would use sda3. And just like the kernel can, GRUB can also address a device without carrying about partitions, so the equivalent of devsda in the instance would be hd0 wrapped in parentheses, of course. AIO Boot also uses Grub2, which saves you a lot of time. You can download Grub2 source code for all platforms here. For Windows, you should download the latest version of Grub2 here.

It supports Windows 7, 8, 8. Once downloaded, you need to extract the downloaded file above. Here I will extract the grub We will now start installing Grub2. In Disk Management is Disk 2, we will remember number 2 here. Installation finished. No error reported. If you want to change the path of the grub directory, change the value of the —boot-directory parameter.

You have now completed the installation of Grub2. Please restart your computer for testing. Configuration The configuration file for Grub2 is grub. The defaults should work fine, but you can change them if desired. Now click 'Manage Boot Menu'.

Add the partitions you want Grub to display at boot time. Detailed instructions will be found by clicking Help. Now click Apply to return to the main Grub2Win screen. When you are satisfied with the options, click OK. Grub2Win will now generate a customized C:grub2grub. Shut down and re-boot your machine. You can now use the Grub2Win menu to select the OS you would like to boot. You can run Grub2Win as often as you like to add, change or remove the systems on your boot menu.

Many items, including Linux boot parms, icons, timeouts and partition addresses can be tailored. Your choices will preserved across multiple runs. If you encounter any errors during installation or while running Grub2Win, please open a topic on the discussion board here:. We will use the 'device' function of the grub-shell to ensure that Grub uses the correct map between the bios drives and linux devices, and also to ensure that Grub uses the hard drive numbers.

The hd2,3 must be how grub sees the partition during boot-up. As a final solution we need somehow Windows to chainload our Linux partition.

If we use easybcd we can avoid having to copy a file from a live cd to our Windows partition and setting up the boot. If we are geeks and classical we will have to edit boot. Once grub has been installed to a partition we need to get its boot sector to a file in order to boot it from Windows. When prompted enter your current user password or your root password in non-sudo systems such as Debian.

If you do not know how to type symbol please only type sudo -i. Now when rebooting if you boot windows you will get a Windows menu with two options: Windows and the new Linux option which will chainload GRUB. Finally there is an optional step that it is removing grub so that it chainloads Windows menu in the first place automatically at boot. This feature is not yet available at the Rescapp program. It is available at the Super Grub Disk included with Rescatux.
