Like many before me had the following problem that after installing Ubuntu (with windows 7 already installed), the grub boot loader wouldnt show windows 7 as a boot option, though i can boot fine if I use the "Choose Boot Device" options on the x220. The difference is that I try using UEFI only so many answers didn't really fit my problem, though i tried several stuffs:

  • after running boot repair it destroyed the ubuntu boot loader
  • custom entry in /etc/grub.d/40_custom for windows which doesnt show up
  • many update-grub and reboots
  • trying windows repair recovery thing
  • while being there i also did bootrec.exe /FixBoot
  • and update-grub and reboot again
  • and finaly because it was so much fun, i installed linux all over again, while formatting and deleting everything linux related before that.

Now that i think of it, Ubuntu also didn't notice Windows being there during the Setup and it still doesnt according to the Boot Info from Boot Repair.

Thanks for your time and attention.

EDIT: additional Info Request

=>No boot loader is installed in the MBR of /dev/sda.

But maybe this is how it is supposed to work?

yea this is ok. boot stuff seems to be on a seperate partition, in my case sda1. I'm very new to this UEFI thing too.

missing files like bootmgr

i don't really have a clue :D but yea, maybe thats how it suppose to be? Instead and whats not shown in the log for some reason: There is additional microsoft bootfiles on sda1 under /efi/microsoft/ [much stuff]

I remember also doing some kind of hack to make a UEFI windows 7 usb stick. http://jake.io/b/2011/installing-windows-7-with-uefi-boot-on-an-x220-from-usb/ In short: creating and placing bootx64.efi on the stick so it can be booted in UEFI mode.

boot order

i decide that in my BIOS. i read somwhere that the thinkpad x220 (essential part of the serial number: 4921 http://www.lenovo.com/shop/americas/content/user_guides/x220_x220i_x220tablet_x220itablet_ug_en.pdf) doesnt really have UEFI interface or something, still, these 2 options are listed with all the other usual devices you can give a boot priority to. Right now it looks like this:

Boot Priority Order
 1. ubuntu
 2. Windows Boot Manager
 3. USB FDD
 4. USB HDD
 5. ATA HDD0 HITACHI [random string]

My Second Attempt

In hindsight I think my previous comments had no value so I removed them.

Your main problem seems to be that update-grub does not (automatically) find and include your Windows install in the grub.cfg "menu" it generates, correct?

  • A suggestion. Consider changing the title of your question to something along the lines of
    Why does update-grub on UEFI Thinkpad laptop not add Windows to GRUB menu?
    This might attract the attention of someone who, unlike me, actually knows what is going on when update-grub probes for operating systems. :-)

I'll paraphrase my understanding of your question so that you can correct me where I am wrong.

I think you have a Lenovo ThinkPad X220 (4291) which uses a UEFI BIOS.

  • Note: 4291 is a guess on my part. What I am trying to refer to is the dddd-xxx code between Type and S/N on this sticker on the bottom of your X220 laptop/tablet.
    Lenovo Machine Type and Model sticker

Your laptop already had Windows 7 installed and working on it. You then installed Ubuntu 12.04 (Beta 2?). However after the install the GRUB menu did not contain an entry to boot Windows 7, correct?

You are still able to boot Windows 7 by entering the BIOS configuration, selecting the Startup menu and then making the Windows entry the first in the Boot sub-menu. But obviously this is a PITA and you would like to have an entry in the GRUB menu you can use to boot Windows.

I am assuming you installed the Beta 2 copy of Ubuntu 12.04. (64-bit?) If so, now that 12.04 has been released have you used update-manager to apply all updates & fixes? (Just checking.)

One of the things you have tried was to add a custom entry for windows to /etc/grub.d/40_custom but it didn't show up. I assume you based this on the Non-Mac x86_64 UEFI specific info section in the Ubuntu Community Documentation?

All I can think of is to suggest trying this once again.

  1. Boot Ubuntu, open a terminal window, and run ls -l /etc/grub.d/40_custom to verify that root owns this file and it is executable.
      -rwxr-xr-x 1 root root 356 Apr 26 14:15 /etc/grub.d/40_custom
  2. Use sudo gedit /etc/grub.d/40_custom to edit the file. I think the content you want it to have is:
    #!/bin/sh
    exec tail -n +3 $0
    # This file provides an easy way to add custom menu entries.  Simply type the
    # menu entries you want to add after this comment.  Be careful not to change
    # the 'exec tail' line above.

    menuentry "Windows x86_64 UEFI-GPT" {
        search --fs-uuid --no-floppy --set=root 885C-ED1B
        chainloader (${root})/efi/Boot/bootx64.efi
    }

Save the file and run sudo update-grub. The edit above should be added to /boot/grub/grub.cfg between the lines ### BEGIN /etc/grub.d/40_custom ### and ### END /etc/grub.d/40_custom ###

If the above steps worked, then try rebooting and see if you now have a GRUB menu entry which lets you boot Windows. (Mentally crossing fingers here.)

First, you should check for the presence of the Windows boot loader on your ESP. Under Linux, this file will normally be present as /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi. If it's not present, check to see if just that one file is gone, or if all of /boot/efi/EFI/Microsoft is gone. Unfortunately, Ubuntu versions prior to 12.04 would wipe out the ESP, including any pre-existing Windows boot loader and its whole directory tree. If this file is missing, the only way to fix it is to restore it from a backup or use a Windows recovery disc to do the repair. Once that's done, you may need to rejigger things again to get GRUB (or some other boot manager) to launch by default.

Assuming the Windows boot loader program is present, there are several ways to fix this problem.

One is to install rEFIt or rEFInd. I forked rEFInd from rEFIt because rEFIt seems to have been abandoned; thus, IMHO rEFInd is the better solution. These programs are both boot managers that, when properly installed, run before GRUB. They can both auto-detect GRUB and the Windows boot loader, giving you the option to boot either one. Thus, it won't matter if GRUB can't detect Windows or fails to launch it.

The second approach is to add an entry to /etc/grub.d/40_custom similar to what irrational John suggests; however, you must change the serial number from 885C-ED1B to whatever it is on your system, or specify the ESP in some other way. Furthermore, you should point the chainloader line at the Windows boot loader, which is /EFI/Microsoft/Boot/bootmgfw.efi. (It might be duplicated at /EFI/Boot/bootx64.efi, but this isn't guaranteed). For instance, this ought to work:

menuentry "Windows" {
    set root=(hd0,gpt1)
    chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

That's from memory, though; it could be I've forgotten something or entered a typo. Also, done in this way, you must specify the ESP correctly on the set root= line; if the ESP isn't the first partition on the first physical disk, you must adjust the numbers appropriately.
