Ubuntu Installation :: Saving Grub Edits At Boot?
Jul 31, 2010
EDIT: Problem solved. I replaced "quiet splash" with "acpi=off" and everything works perfectlyI have installed Ubuntu 10.04 on a hard-drive partition, but I have yet to have it boot successfully. The boot starts normally, but then the screen goes blank.I am currently trying this solution:Quote: * At install screen press F6 and select nomodeset and install Ubuntu as usual.* On first boot after install, press e on getting the GRUB bootloader.* Using arrow keys navigate to and delete quiet and splash and type the word nomodeset in their place* Press Ctrl and X to boot* You should now be able to login to your Ubuntu as usualHowever, it seems that I am unable to get the changes I make in grub (changing "quiet splash" to "nomodeset" in the screen brought up by pressing 'e' when booting) to save (update) correctly. How is this done?I have tried bringing up the command line and using 'sudo update-grub', but sudo is unrecognised. Note: I am using a MacBook 5,2; which has reportedly had some difficulties with Ubuntu requiring a few orkarounds.

Basically my laptop did have a Windows 7 partition that came with the system(which I no longer need), a Ubuntu partition and a separate partition for storage. This was until I formatted the separate partition using Windows and it did something which gave me a file system error and would not let me boot into any os. Then because I was in a rush and had lectures in a hour I installed another Ubuntu partition of 3gb just to reinstall GRUB so I could boot into my original Ubuntu to get my files. Now I would like to delete the 3gb Ubuntu partition and the Windows partition to be left with my original Ubuntu partition and then merge the hard drive into just the one partition. My main fear before I attempt this is again destroying my GRUB. I know I have made a mess of this but would really appreciate being pointed into the right direction. I have done some searching and reading but struggled to find clearish instructions on how to do it properly.

I tried to change the default colours in the Grub 2 Boot loader following instructions in: [URL] pecifically colors are set by: set color_normal=black/black "set color_highlight=magenta/black" in /etc/grub.d/05_debian_theme I opened as root and edited this file but the changes done seem to stick. It's still all black/white when I boot.

The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).

I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:

I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

I'm trying to dual boot Win7 and Ubuntu WITHOUT using Grub. This is to support Bitlocker encryption.
I followed this guide, and now when I select Ubuntu I get a Grub> prompt and no ubuntu.
I feel like I'm halfway there, I just need to get Grub to load correctly or something.

I'm running Rythmbox 0.13.1 on Ubuntu 10.10 netbook edition.
My problem is that edits I make to tags sometimes don't save in Rythmbox. After I make the edit and click save it appears to have changed. (IE, the genre will change or the comment section will be different.) But if I reboot Rythmbox it has reverted to its previous state.
Not sure what's going on. Is this something I should fix or should I file a bug report and wait for the next version of Rythmbox?

I updated from Ubuntu 9.10 to 10.04 via Ubuntu updater. Worked nicely. Until I had to use Win 7 for a moment, so I went to the Grub boot menu and picked Win 7. Nothing is happening. Just a black screen with blinking underscore to the top left corner. I never had this problem with 9.10, so I am confused. I tried looking around and nothing helped. Be noted that I am an amateur with Ubuntu coding and installing. I did hear that this is already a common issue now.

I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.
I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).
I installed grub on the Fedora disk so as to not touch the windows disk at all.
Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)
My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

Write some simple script?
Heres what Im trying to do:
-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).
-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.
-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)
PRESET1=alsa
PRESET2=firewire
I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.
Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.

i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

I need to install linux (with Grub) un a disk with windows 7 loader (i have 2x choice on that loader and i need to use it).
I tried to dig to find out some methods but nothing.
It's safe? It's better to install Grub on another partition - same physical disk?

I found a little info in the ubuntu help info but their method (using the grub command line to find the USB, then using chainloader +1 to boot from it) did not work. heir method of using a minimal linux kernal sounds extraordinaraly complex, and perhaps not even possible since I do not have a CD drive in this computer.The problem is, I cannot boot my netbook from the USB anymore. The netbook is an EeePC 900HD, which ran WinXP originally. I was able to access the BIOS before installing UNR and set it to boot from the USB before the HD.
However, it now appears that this grub thing has replaced the netbook's original BIOS and now I cannot boot from the USB anymore. Using Google, I found info in the Ubuntu documentation that details how to boot from USB with grub, but their method did not work. When I use the grub commands to identify the various HDs, I get the following:
"root (hd0,0)" returns "error: no such partition."
"root (hd0,1)" returns "(hd0,1): Filesystem is ntfs" [THIS IS MY WINDOWS XP PARTITION]
"root (hd0,2)" returns "(hd0,2) : Filesystem is unknown" [I THINK THIS IS MY UBUNTU PARTITION"

I am doing a pure 10.04 Ubuntu installation (no other OS involved) on a NEW hard drive. I am doing this with an alternate install CD.Like the person in the other post, I am receiving this menu:
Quote:
GNU GRUB version 1.98-1ubuntu5Minimal BASH-like line editing is supported. for the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

It's an improvement since I was in the grub rescue mode for a while there.ls command lists the following devices (hd0) and (hd0,1). The root directory is (hd0,1).I've tried formatting with Parted Magic and the "live CD" doesn't boot.Could you please give some help which isn't too technical: I really am lacking in patience here as this has been going on for several days. And I've been trying to decode [URL]I can get into the grub.cfg file using Parted Magic and it looks like this:

I installed F14 from my usb according to the wiki page using unetbootin. The usb boots perfectly and i get a working F14 system. I partitioned my HD with gparted and got a /,/home and swap partition, then used the installer to install the system using them. The installer finishes without a problem and ask me to reboot. When I reboot , there is a blank black screen. No grub menu , no fedora loading. I reboot with the usb and the partitions are full with the files from F14 , there is no xorg.log in the /var/log/ so f14 doesn't even start so the problem seems to be with grub.
I check the grub.conf in /boot/ , i set the timeout to 5 secs , i check that the kernel is using nomodeset (according to this wiki page there is a problem with ati), xorg.conf is using vesa as a driver and I reinstall grub with grub-install with no problems.My notebook is a acer aspire 5552 , i don't think is a hardware problem because I've used arch and opensuse with no problems in it. Fedora seems a nice distro , but this error is preventing me from using it.

I'm a long time windows user and it-tech but I have long felt that my geek-levels were too low so I installed Ubuntu last week (9.10 x64). Hopefully I can make it my primary OS. I have two 80GB drives in RAID-1 from my nforce raid controller, nforce 570 chipset. Then a 320 GB drive where I placed ubuntu and it's also where grub placed itself. And also a 1TB drive.
When grub tries to boot XP I get the error message: "error: invalid signature" I checked the forum as much as I could and tried a few things, but no change.
Drives sdc and sdd are the two drives in raid, they are matched exactly, but detected as different here. I really think they should be seen as one drive.
how I can make grub work as it should?
Also, if/when I need to make changes to grub, do I really have to use the live CD?
Code:
============================= Boot Info Summary: ==============================
=> Grub 1.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb
=> Windows is installed in the MBR of /dev/sdc
