Nothing has changed I keep getting this after I update GRUB

Code:

---

michael@michael-laptop:~$ sudo update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.31-20-generic
Found initrd image: /boot/initrd.img-2.6.31-20-generic
/etc/grub.d/10_linux: 126: single : not found

---

I'm assuming 126: is line 126 which is the new last line after I did the first modification a couple of weeks back. When I reboot I still have the normal non title recovery selection while the non recovery says Karmic.

I'll keep playing around with it, and I'll give it a go on Lucid later to see if that behaves differently.

k3lt01,

This just means there is an error somewhere in script. Line 126 is the last line in your file. The script is telling you that it went all the way to the end of the file and there were still issues yet unresolved. In this case, it involves the line with "single" in it.

It could be something as simple as an extra space at the end of the line, the way the quotation symbols are interpreted in your text editor, etc. Also make sure you don't have an old script (for instance 10_linux.bad) in the /etc/grub.d folder that is still executable. Any executable file in the folder may run when update-grub is invoked.

I don't have the time right now to go through the script and troubleshoot it, although running it on my computer currently produces no errors. I'll try to explore it more completely as soon as I have a bit of free time.

Added: I was able to generate the same error message you received by placing a space at the end of the line prior to the line containing "single".

Fixed it, it was the line above "single"

Code:

---

linux_entry "${codename} ${version} (recovery mode)" \

---

The issue was something to do with spacing it made no difference where the line started in the original file but in the modified file that line had two spaces to many at the start.

Thanks again for your help.

Perhaps I'm wrong, but it appears that the end quote comes too soon (before the (${shortdevice}) part of the name). Thus, it should look like:

Code:

---

menuentry "${LONGNAME} (${shortdevice})" {

---

This typo appears again in the subsequent title tweak as well...

Larkster,

Thank you for pointing this out. Corrected in the original post.

And welcome to the Ubuntu forums. :-)

Thank you for such a great post. I'm glad there are other people out there that are anal about the appearance of their Grub menu too. At first I was very cautious about modifying it, for fear of messing something up, but now I feel like I've learned so much from going through this tweaking process. Thanks!

Great tutorial and so easy to understand i like it ! =D>
Anyway I found this trick will remove a menu entry or even a linux recovery while i playing around with it. :) hope it work and not double post.

just assign value '--' to LONGNAME (LONGNAME = "--") or linux_entry (linux_entry "--")

Remove a windows menu entry

Code:

---

if [ "${LONGNAME}" = "menu title here" ] ; then
  LONGNAME= "--"
elif [ -z "${LONGNAME}" ] ; then
  LONGNAME="${LABEL}"
fi

---

Remove a linux recovery mode

Code:

---

# ORIGINAL linux_entry "${OS}, Linux ${version} (recovery mode)" \
linux_entry "--" \

hi.....I have Lenovo Y500 series laptop and I found that when ever I boot system , my keyboard worked some times and some times not .Same thing was happening with my touchpad.

After some googling I found out that it’s neither a problem of Operating System nor a misconfiguration of X11 config file.

It is a problem related to acpi and the 8042 interrupt controller conflicts.

So to get rid of this problem is to edit your grub configuration file ./boot/grub/menu.lst ( on ubuntu) and append the following line to the kernel argument.

locale=fr_FR i8042.reset
but with grub2 i dont understand where to append the following line....

Code:

---

default=0
timeout=5
splashimage=(hd0,5)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-164.11.1.el5)
root (hd0,5)
kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet splash
initrd /initrd-2.6.18-164.11.1.el5.imga

---

I have highlighted the line the be changed. Append the ‘locale=fr_FR i8042.reset’ to the following line.Depending on your grub file, you have to find line having kernel and modify it. After the changes, file is.

Code:

---

default=0
timeout=5
splashimage=(hd0,5)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-164.11.1.el5)
root (hd0,5)
kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet splash locale=fr_FR i8042.reset
initrd /initrd-2.6.18-164.11.1.el5.imga

In the previous version my USB entry looked like this:

root: (hd1,0)
make active: yes
chainloader: +1


so if someone can help me in creating one entry for GRUB2 for booting USB devices I would be really thankful.
