GRUB: failed to add custom entry


Hi all, first let me introduce myself:
Code:
$uname -a
Linux localhost.localdomain 3.12.8-300.fc20.x86_64 #1 SMP Thu Jan 16 01:07:50 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
I have rencently installed Fedora on my Samsumg ultrabook, and GRUB did not find my windows partition.
After reading a lot, I tried what is described bellow, but the windows entry still does not appear on my initial GRUB screen.

What I did was to edit the file /etc/grub.d/40_custom to read:
Code:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Windows)" --class windows --class os {
insmod part_msdos
insmod ntfs
insmod ntldr
set root='(hd0,msdos4)'
search --no-floppy --fs-uuid --set=root 1024008A240074CE
ntldr ($root)/bootmgr
}
I found the partition to be sda4 via fdisk -l, which gives
/dev/sda4 1902592 109708465 51.4G Microsoft basic data

and found the UUID of the partition via
Code:
#blkid
/dev/sda4: UUID="1024008A240074CE" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="b37fee96-7786-40f7-8b2c-2e2bb7cbda6e"
After this I ran grub2-mkconfig
Code:
# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.12.8-300.fc20.x86_64
Found initrd image: /boot/initramfs-3.12.8-300.fc20.x86_64.img
Found linux image: /boot/vmlinuz-3.11.10-301.fc20.x86_64
Found initrd image: /boot/initramfs-3.11.10-301.fc20.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-7278e60551444810a17394e52db51827
Found initrd image: /boot/initramfs-0-rescue-7278e60551444810a17394e52db51827.img
and saw that the 40_custom entry appears in the /boot/grub2/grub.cfg file

The problem is that, after all this work (that looked fine to me), no entry for windows appears on GRUB initial screen (when I turn on my computer)

can someone give me a hint on what is going on?

thanks in advance

Do an online search for 'bootinfoscript', go to the site and read the instructions then download it and run it. Post the output, a results.txt file which will provide detailed information on your drives/partitions and all the boot files, their location and the menuentries.

Well, for my Win7 system, the blkid looks like this:
Code:
# blkid | grep sda1
/dev/sda1: LABEL="SYSTEM" UUID="98CAD0A9CAD08542" TYPE="ntfs" PARTUUID="945663c5-01"
and, modifying the menu entry created by grub2-mkconfig and putting it in /boot/grub2/custom.cfg, like this:
Code:
# cat /boot/grub2/custom.cfg 
menuentry 'Windows 7 (ntldr test)' --class windows --class os $menuentry_id_option 'osprober-chain-98CAD0A9CAD08542' {
  savedefault
  insmod part_msdos
  insmod ntfs
  insmod ntldr
  set root='hd0,msdos1'
  if [ x$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  98CAD0A9CAD08542
  else
    search --no-floppy --fs-uuid --set=root 98CAD0A9CAD08542
  fi
  ntldr ($root)/bootmgr
}
works with no problem.

Note that, by placing the menu entry code in /boot/grub2/custom.cfg you don't need to re-run mkconfig to implement your changes. provided you have a 41_custom like this:
Code:
# cat /etc/grub.d/41_custom
#!/bin/sh
cat <<EOF
if [ -f  \${config_directory}/custom.cfg ]; then
  source \${config_directory}/custom.cfg
elif [ -z "\${config_directory}" -a -f  \$prefix/custom.cfg ]; then
  source \$prefix/custom.cfg;
fi
EOF
in your /etc/grub.d directory so that block of code is in your grub.cfg file. (In fact, as you can see, the menu entry (or entries) can be in either ${config_directory} or ${prefix}. On my system, those are, respectively, /boot/grub2 and /boot.

Thanks for the reply

I don't know if I fully understood you, but I created the file /boot/grub2/custom.cfg (it didn't exist) and pasted with your code replaced with my UUID and partition, such as

Code:
cat /boot/grub2/custom.cfg
menuentry 'Windows 7 (ntldr test)' --class windows --class os $menuentry_id_option 'osprober-chain-1024008A240074CE' {
  savedefault
  insmod part_msdos
  insmod ntfs
  insmod ntldr
  set root='hd0,msdos4'
  if [ x$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos4 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos4  1024008A240074CE
  else
    search --no-floppy --fs-uuid --set=root 1024008A240074CE
  fi
  ntldr ($root)/bootmgr
}
After this I restarted, but still, no entry appears on the intial grub screen..

What else can I do?

You do have an entry for windows for sda4 in the grub.cfg file so I don't know why you don't see it. You also have an EFI partition and I don't use UEFI and don't know if that might be part of the problem.

Hey colorpurple, thanks for the corrections, but I fixed that and still don't see the entry when booting

Anyone could give me something new to try?

You show it correct in post 4, but not in the bootinfo script in post 5. Where did you edit the entry. According to this http://www.rodsbooks.com/efi-bootloaders/grub2.html grub-mkconfig has to be rerun on efi for changes to custom file to take place.

I ran bootinfo script before correcting as you said, so that is why the mistake is there

I did run "grub2-mkconfig -o /boot/grub2/grub.cfg" all the times I changed stuff.

thanks for answering, though

What is in /boot/efi? Should be a directory in there for Fedora with possibly a grub directory within it. If so try copying and/or run grub2-mkconfig -o /boot/efi/fedora/grub2/grub.cfg see if that fixes the problem

From what you posted from the bootinfoscript output, it looks like your grub.cfg file includes the code to load the custom.cfg file. (It's the last few lines of the grub.cfg file listed in your post.) The only thing that could cause it to fail to load is if you placed in the /boot/grub, and your grub.cfg file is in some other place. (I looked at the logic a little more closely, and noted that it only looks in ${prefix} if ${config_directory} is not defined.)

Have you tried going into the GRUB2 command mode (Push the <ESC> key when the first menu is entered, and then a C. [The 'C' is from memory, so check the instructions at the bottom of your screen after the escape.]) and using the configfile <actual path>/custom.cfg command to see if the your custom.cfg file works?

(Oh, before you do that, after you get the grub> prompt, the set command will show you all the currently set values.)

Aside: The above "trick" is one way to have boot menus for, e.g., bootable USB devices that you seldom want to actually boot and not have your "everyday" menu cluttered with those entries. (A better way, of course, is to have those boot options as submenu entries in the custom.cfg file.)

<edit>
Well, I thought to try this when I booted this morning, and I had a "few" errors:
  1. The "escape" is not needed: Just type a "c" when the menu is displayed. (The instructions are at the bottom of the menu page.)
  2. When I ran the set, I found that, on my system, ${root} setting. It's not /boot: it's just /, prefix is /boot/grub2, and config_directory is not defined.
With that, a simple configfile $prefix/custom.cfg displayed (just) my custom menu entry.

But, in your case, you've found that your prefix value is /boot/efi/EFI/fedora/, so either move the custom.cfg file there, or run it "by hand" as I describe above to see it it will work.
</edit>

hey guys,
so I checked the URL sent by colorpurple, and tried their version of /etc/grub.d/40_custom, which now shows the entry in Grub screen, but it fails to load. Now my custom entry is:

Code:
# cat /etc/grub.d/40_custom 
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Windows" {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --no-floppy --fs-uuid --set=root 1024008A240074CE 
chainloader (${root})/efi/Microsoft/Boot/bootmgfw.efi
}
and it gives the error
Code:
error: file '/efi/Microsoft/Boot/bootmgfw.efi' not found
but now I think it is just a matter of finding the correct boot image for windows.

Also,
Only now did I realize that my BIOS has the "secure boot" option disabled.
and it always gives a "Booting in insecure mode" message before entering GRUB

Still could use some help, if you guys don't mind

thanks for everything.
