I have two hard drives and two GRUB versions. Windows still relies on the old version that I want to remove. How can I make Windows Boot Manager talk only to my new GRUB version.
I started off with triple boot of Win7, XP, and Ubuntu 10.04. I have GRUB version 1.98 on the sdb drive. In order to boot into Windows, I select Windows 7 from the list and it takes me to the Windows 7 (Loader) /dev/sdb1 screen where I can select either Win7 or XP. All this works fine.
Then I decided to load Ubuntu 14.04 on another hard drive. This drive is seen by the system as sda. After loading my old Ubuntu 10.04 and running update-grub, I can see my new Ubuntu 14.04 from the GRUB 1.98 menu- no problem here.
The problem comes up when I boot directly into my sda drive. Here I see the GRUB 2.02 menu that comes with Ubuntu 14.04. When I pick Win7 from the list it takes me (properly) to the Windows Boot Manager, but then it goes back to my original GRUB 1.98 menu. The idea here is that I want to remove the Ubuntu 10.04 (with GRUB 1.98) partition and leave Win7 and XP on one drive, and keep Ubuntu 14.04 on the other drive. But if Windows is dependent on my old GRUB install, I am afraid I will not have access to Windows.
Disk /dev/sda: 20 GB,
Device Boot Start End Blocks Id System
/dev/sda1 * 1 2310 18553856 83 Linux
/dev/sda2 2311 2434 994305 5 Extended
/dev/sda5 2311 2434 994304 82 Linux swap / Solaris
Disk /dev/sdb: 250 GB,
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 6133 49263291 7 HPFS/NTFS
/dev/sdb2 6134 7977 14811930 7 HPFS/NTFS
/dev/sdb3 7978 12748 38323057+ 5 Extended
/dev/sdb4 12749 30402 141797376 7 HPFS/NTFS
/dev/sdb5 7979 12499 36314932+ 83 Linux
/dev/sdb6 12500 12748 2000061 82 Linux swap / Solaris
So my new GRUB 2.02 and Ubuntu 14.04 are on the 20GB drive labeled sda, sdb1 has XP, sdb2 has Win7, sdb3 is an extended partition which contains sdb5 and sdb6 which have my Ubuntu 10.04. The sdb4 partition is just common storage space.
The commands: sudo dd if=/dev/sda bs=512 count=1 | hexdump -C sudo dd if=/dev/sdb bs=512 count=1 | hexdump -C
show that there is a GRUB version in the MBR of each drive.
I would like to know how to set up my windows boot manager so it only talks to the GRUB on my sda drive and not to the GRUB on the sdb drive (GRUB 1.98). When I am done I would like the following configuration:
- sda: Ubuntu 14.04 with GRUB 2.02
- sdb: Win7 and XP with no GRUB at all
