I used to have a grub menu with options of
*Ubuntu
*Ubuntu Recovery Mode
*Memtest
and
*Windows
but later I installed Ubuntu alone on a machine , and i do not have GRUB menu. and i want to enter the Recovery mode.
I started a thread over in installations and upgrades in which I was trying to upgrade from Ubuntu 10.04 to 10.10 using the upgrade manager. My computer froze in the middle of the process, requiring me to restart my computer. When I try rebooting Ubuntu, I get an error message "The configuration defaults for Gnome power manager have not been installed correctly" and then a blank screen. No mouse pointer, no cursor. It will not take me to the Ubuntu desktop screen. I've already found the sudo commands I can run to try and fix Ubuntu. They are as follows:
sudo apt-get clean (If the problem is not having enough free hard drive space)
sudo dpkg --configure -a (If the problem deals with the upgrade installation process)
However, what I can't get is the terminal to come up to run these commands. In the other thread I started, someone mentioned that in the Grub menu, you can choose "recovery mode", hit "enter" to boot it, and it will give you a menu of options to choose from. However, when I choose "recovery mode" and hit "enter", I do not get a menu but instead 3 pages of data about my computer that ends with this:
"Begin: Running/scripts/init-bottom...
Done. "
It gives me a blinking cursor at the very end but I cannot type anything and I cannot page up to see the 3 pages of data. What I am looking for is a way to get to the recovery mode menu OR somehow open up a terminal so I can run the sudo commands. My computer automatically logs me in, so I do not get a login screen and Ctrl+Alt+F1 does not work for me. Anyone know how I can open a terminal with only access to the Grub menu? Perhaps a BASH command that I can use in the command line that will open up a terminal? To summarize: My computer does not boot Ubuntu. I get an error message followed by a blank screen. It does not go into the desktop screen so I cannot choose Applications->Accessories->Terminal.
My Grub menu consists of Ubuntu and it's version, Ubuntu and it's version with recovery mode, memtest, and Windows XP (I have a dual boot system). In the Grub menu, I can select "e" for edit, "c" for command line and "enter" to boot either regular Ubuntu OS or Ubuntu recovery mode. "Sudo" commands are not recognize if I choose the command line for either Ubuntu OS or recovery mode. I have a Live CD for 10.04 but you cannot run sudo commands because you do not have access to root on the Live CD.
I messed up my video drivers and now can't get into recovery mode. Pressing the shift key isn't working. All that happens is the splash screen appears in faded looking colors and then fades to white.
I've got an ASUS N61 laptop with an ATI Radeon 5730 graphics card. I just upgraded to 10.10 from 10.4 and was trying to install the open source video drivers. I must have messed something up and can't get to the terminal now.

I've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.
View 2 Replies View RelatedEarlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.
I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD?
I broke sudo when I wrongly edited a file in /etc/sudoers.d in vi(did not use visudo :-().I read that I could fix the same by rebooting into the 'Recovery Mode' by selecting the same from the grub menu.
However I'd earlier disabled the showing of the grub menu by editing /etc/default/grub. As a result I can't seem to go into recovery mode to fix my broken sudo.
I recently reinstalled Ubuntu 10.04. Since I did that I have had a problem with GRUB: I cannot see the Recovery Mode menu - at least not anything intelligible.
I can see the normal first GRUB menu with all installed operating systems, recovery modes, and MEMTEST, etc, but cannot see the Recovery Mode menu. What I do notice (if I select it) are some fuzzy lines at the top of the screen. I also notice the Ubuntu splash screen does not appear any more either.
Clearly it seems there is a resolution issue. I have a 1440 x 900 monitor and the current version NVIDIA driver.
This happened some time ago on previous Ubuntu releases, but was not an issue when I originally installed 10.04.
Attempted Fix:I installed the StartUp-Manager and have tried all the resolution combinations with no success. Some yield bigger more centrally displayed fuzzy lines, but still nothing legible.
Although this isn't "life-threatening" I'm just a bit worried that I might need the Recovery Menu and not be able to use it.
I am trying to install ubuntu 10.04. I had ubuntu 10.10 but I want to install 10.04 (32 bit) because 10.10 is slow. Problems with cd drive/cd caused installation to be incomplete so system cannot reboot at all.

New to Ubuntu and trying to ensure I can boot into Acronis Recovery Manager to be able to reimage Windows as and when appropriate. If I enable the Acronis Recovery Manager so that it overwrites the MBR then I run out of ROM I think which prevents it from loading. If I use the software CD that doesn't detect my sata drive. However, I made a rescue CD in Acronis and this does work but I'm only using my bootable CD drive temporarily in this system.I found this post (URL...) which seems to do what I would like and have managed to follow this to extract the files from my rescue CD into /boot/acronis. However this original post relates to Grub and as a newbie to Ubuntu I think I have Grub2. I can't figure out what the correct syntax is to make a new Grub Menu entry in /etc/grub.d/40_custom.

I recently removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.
View 1 Replies View RelatedI attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?

View 9 Replies View RelatedI updated to 11.04 recently, no problem. Chose to merge the old and new Grub files together. Rebooted to finalize everything, and my Grub menu had lots of doubling up of options, the old kernel, as well as two options of Windows XP (the old option that I'd put on Grub, and what I suspect was 11.04's recognition of another partition, as it was titled "Windows XP ... (on dev/sda2)")Then I fired up Grub Customizer, re-read and double checked everything, and removed all the doubling instances. All good. Shut down for the evening.

I am effectively an Absolute Beginner when it comes to the terminal - I know a couple of commands, am eager to learn more when I have the time, but really couldn't tell you what the hell I'm doing. The last thing I want to do is make this worse by fumbling through code. This isn't Zork.If anybody would be kind enough to provide the terminal commands to change the Grub menu to add regular partitions, I'd be very grateful. If there's a different fix, equally good. If anybody's got any comments, diagnoses, verbal abuse, heap it on. I'm here to learn.
Ubuntu 10.10 doesn't boot at all. The liveCD only boots once every like 30 attempts, installing from liveCD froze, but the Alternate CD worked and installed ubuntu. Now when I try to boot into it using GRUB, it freezes at the beginning of the boot process.With normal boot it freezes at line: Starting AppArmor profiles Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox.With recovery mode it freezes even before showing me anything
A little kinda like the liveCD, if I try like 30 times, it might manage to boot once in normal mode.That line keeps on repeating, the the xxx.xxx integer changes each time, and this goes on forever.I tried removing my floppy drive, but it didn't help.I tried to boot with fd0=noprobeThe one time it booted, when I restarted, it froze while trying to restart.
I have never in a year had a problem with this d-boot system. Two days ago I tried to boot into ubuntu like every day. It started to load normal, went to the ubuntu logo and paused for about 15 seconds and posted this under the logo:
One or more of the mounts listed in /etc/fstab cannot yet be mounted
/: waiting for /dev/loop0
/tmp: waiting for (null)
/boot: waiting for /host/ubuntu/disks/boot
Press ESC to enter a recovery shell
I have looked everywhere and tried so many things, I can't look any further. All I have been doing for two days is trying to boot this system.
My problem is that I am trying to install an Nvidia driver on ubuntu 10.04, and I can not access my console mode by pressing ctrl alt f2. When I press that keystroke my cursor will disappear till I press alt f7.

View 3 Replies View RelatedAfraid I'm an utter newbie. I'm using 10.04 64 bit. I only noticed this after I tried to install the NVIDIA driver and all my ubuntu os'es blackscreened after restart. Because I couldn't even access recovery mode, I ended up reinstalling ubuntu, overwriting the old root.I thought the problem was due to the driver, but it's even now persisting. I can run the terminal (within X?) but if I try ctl alt <F1-6>, the screen just freezes until I do ctl alt F7. Furthermore, recovery mode still leaves a black screen after the initial loading text. I need it to work before I attempt reinstalling the NVIDIA drivers again, as I don't want to reinstall the OS and all the programs.
Sometimes it feels like I can do stuff in recovery mode, like Ctl Alt Delete or sudo shutdown, but sometimes not. Not sure if this is related, but grub also lists windows vista and windows recovery as the opposite they should be (I thought my windows was completely screwed until I tried windows recovery).
I have a HP mini 2133 with Ubuntu 10.04 NBR installed, but because the CMOS battery went flat and the date on the BIOS got reset to 1980, I now get a failure starting the machine (Superblock failure: Last mount time is in the future). I've already googled on this error, and the general advise seems to be "run fschk and let it complete", but my question is...I don't get a grub screen come up when Ubuntu boots, and Contrl/Alt/F* doesn't bring me to any login windows. So how do I interrupt the startup, and get to a login window before I get the mount error.

View 9 Replies View RelatedI am testing my crash recovery strategy for my linux system and I am having trouble with GRUB. I am basically restoring my backup (i.e. tar) unto a different hard drive, but I am having problems getting the machine to boot without me having to type the GRUB commands at the GRUB prompt that is presented when the machine boots up off the new hard drive. I have tried to restore the MBR in two ways (the 2nd one is the one that gets me to the GRUB prompt):
1. Get the MBR off the original drive and write it unto the new drive (all via dd), but that did not work at all: the machine hangs right away during boot up. It seems to hang right at the point where the BIOS tries to read the MBR.
Code:
On original drive:
# dd if=/dev/sda of=mbr+part.bin bs=512 count=1
On new drive (new drive is now in place of original drive):
# dd if=mbr+part.bin of=/dev/sda bs=1 count=446 conv=notrunc
2. By using the FEDORA rescue CD, I installed grub unto the new hard drive as follows:
Code:
# chroot /mnt/sysimage
# grub-install --root-directory=/boot hd0
reboot and remove FEDORA CD Using the 2nd option above, I get the GRUB> prompt during bootup. I can then boot into the system by issuing the commands that are in the menu.lst file, followed by the "boot" command. However, I would like for those commands to happen automatically, just like in the original configuration. It seems to me that GRUB is actually finding all its stage files because I doubt the GRUB program (the one displaying the prompt) fits entirely in the 446 bytes it has on the MBR. So, it must be loading its stage 2 (and stage 1.5??) files from my /boot partition. However, if GRUB is loading its stage files off the boot partition, why does it not load/read the menu.lst/grub.conf contained in the boot partition also?
Code:
# ls -l /boot
