Hello,
I cannot install grub to my ESP it seems. I have a PC with both Windows 8.1 and Debian installed and I can only boot into Windows since GRUB is not installed on my PC.
I am using a Ubuntu Live USB to install GRUB on /dev/sda1 (my ESP).
I am using the following commands from Ubuntu Live USB-:
Code:
sudo mount /dev/sda7 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt /bin/bash
After this I am executing-:
Code:
grub-install /dev/sda1
After executing that I am getting the following output-:
Code:
root@ubuntu:/# grub-install /dev/sda1
Unrecognized option `/dev/sda1'
Usage: grub-install [OPTION]
Install GRUB on your EFI partition.
-h, --help print this message and exit
-v, --version print the version information and exit
--modules=MODULES pre-load specified modules MODULES
--root-directory=DIR install GRUB images under the directory DIR
instead of the root directory
--grub-mkimage=FILE use FILE as grub-mkimage
--grub-mkdevicemap=FILE use FILE as grub-mkdevicemap
--grub-probe=FILE use FILE as grub-probe
--no-floppy do not probe any floppy drive
--recheck probe a device map even if it already exists
grub-install copies GRUB images into the DIR/boot directory specified by
--root-directory.
Report bugs to bug-grub@gnu.org.
Can anyone tell me what I am doing wrong ? Why is /dev/sda1 a unrecognized option ? I am at my wits end with this. Unless GRUB is installed I cannot use Debian I can only use Windows.
Do I do this before chrooting into my Debian system from my Ubuntu Live USB ? Or do I execute this after chrooting into my Debian system.
When I execute-:
$ sudo grub-install --root-partition=/mnt /dev/sda1 won't it install GRUB to /mnt and not my ESP ? Also won't it install the GRUB version found in Ubuntu, rather than the one found in Debian which is the one I am trying to install ?

sudo mount /dev/sda7 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt /bin/bash
Then I executed-:
$ grub-install --root-directory=/mnt /dev/sda1
The got the following output for that-:
Code:

When I ran the following command-:
Code:
grub-install --root-directory=/mnt
I got the following output-:
Code:
/mnt/boot/grub doesn't look like an EFI partition.
It seems its a problem with the Grub configuration.
Take another look at the link I posted in my post #3.
That guy had a EFI partition, like you. He installed Debian, like you.
He found that a bootloader was not installed, like you.
He was trying to dual boot Windows, like you.
He spent a lot of time but was good enough to publish his solution.
Hi,
Can we specify which grub.conf to use while installing grub on RHEL.
We are working on application which requires different grub configurations needed, depending on certain criteria we need to update grub with correct grub.conf.
Can we use grub-install for this purpose? (4 Replies)
