GRUB vs. Win7

[Slurhn]

Q: How do I make this boot Windows from GRUB??

 

I have a dualboot system with Ubuntu and Windows 7 from two different drives. 

I would like to boot both from withing GRUB installed on the Ubuntu system, but for some reason Win7 is not found by the OS-PROBE and coding in an additional option (40_win) did not work.

 

My main error is from GRUB itself when I choose the option I coded in using a number of different resources:

 

a couple times:

"Secure Boot forbids loading module from (hd0, gpt2)/grub/x86_64-efi/..." ( each with a different module listed: ntfs, ntldr, and a couple more.)

"failure reading sector ****** from 'hd1'." (hd1 is an empty hard drive

 

Info:

GNU GRUB version 2.00-19ubuntu2.1

Ubuntu 14.10 that runs on an encrypted HDD (one of my guesses is that I cannot load kernel modules from the HDD)

Windows 7 SP1 using GPT (another problem, there is something about GPT and GRUB that apparently makes problems)

update-grub

This should automatically add your Windows 7 partition to the boot loader.

I might add that I can google things. Simple solutions like update-grub don't work, and multiple drives work with GRUB flawlesly

(sorry for being sarcastic)

No idea how to help you on your problem, but to change the topic title, click "Edit" under your post, then click "Use Full Editor". Then the Title will be edit-able above the post.

I have used the grub bootloader to dual boot windows 7 and linux mint (basically ubuntu), even off of different hard drives and had no problems like this, it worked fine. When using the grub update command in linux it found windows 7 and worked. Maybe try to reinstall the grub packages off of the ubuntu repo???

 

Edit: If not, then my guess would be that the encryped hard drive is the problem.

This is due to it being on two different drives I think

I don't think so, i had debian on one of my SSD's and Windows 8.1 on the other, however when i would boot into grub it would always give me an option of either OS without any configuration, but i guess that's debian perhaps ubuntu didn't install grub properly in his system.

Probably I was just speculating as i have never had two os on two different drives and tried to boot through grub
