Ubuntu :: Cannot Boot Correctly On Machine, Stuck In MemTest86?
May 1, 2010
I upgraded my 9.10 Ubuntu install last night using the Update Manager, everything downloaded fine, and appeared to install correctly. When it finished I got the message advising that my machine needed to reboot for changes to take effect. I checked my mail quickly before rebooting, and then let it do its thing. It shut down fine, then booted up and went into MemTest86. No real worries, so I wandered off expecting it to take 10-20 minutes. After 4 hours, though, I was starting to worry. A message at the bottom of the screen advised something along the lines that the test had been successful, and I could press Escape to exit.
I did, and my machine rebooted, and went back into MemTest86. I just figured I was being too impatient and left the test running all night. My machine has now been running MemTest86 for 16 hours, and while the timer is still running and the tests refreshing, my keyboard is not responding.

I'm stuck in Memtest86, everytime i boot it gives me an option to go into BIOS, and then it says "Loading GRUB." After that it automaticly goes into memtest, and I've let it finish numerous times without giving me errors. I've installed Linux Mint 8 via Unetbootin, I have a nearly fresh install of windows 7 on my laptop.

Just received Intramfs update, within the hour (4/22/10 11:47 central) , installs correctly on a new 10.04 install but now machine cannot bootIt is somehow resetting the video it appears as the boot screen comes up in different (larger) type. then blanks and all activity stops,, I have been having similar problems if I apply all updates after an initial install of 10.04 but if I hold the opne gl modules the system will work but a backup taken with Remastersys made after the open GL installs will not work while the one made prior to the open GL install will restore the system so I'm guessing some sort of erroneous HW reset sequence

I had a working 10.04 installation and everything was good, then i compiled my own kernel and screwed things up. So I reinstalled and installed my graphics drivers. But Ubuntu can't seem to get my correct resolution. So I am stuck at 1360x768.

The devices tab under ubuntu one preferences lists only <LOCAL MACHINE> the staus at the top says disconnected, the connect button is grayed out and the reset button at the bottom right does nothing. Files don't sync etc but I think this is as a result of the situation described above. I have tried on the advice of an older thread to delete the token for Ubuntu one from 'passwords and encryption keys' and then revisit Ubuntu one preferences in order to sign in again and grant my computer access but this made no difference.

Forgive the terseness. I'm frazzled with this issue, perhaps I should have asked earlier. Every weekend for the past 2 months has been an endless cycle of 'repair broken system' off the install disk.
Installed from Ubuntu server 10.04LTS x86_64, + xfce-desktop Here is uname -a Linux ournas 2.6.32-25-server #45-Ubuntu SMP Sat Oct 16 20:06:58 UTC 2010 x86_64 GNU/Linux If I add my raid + lvm to the fstab file, the boot stalls, (no error it, just hangs waiting, forever). So that's a not very user friendly to start with.
I've tried the suggestions about UUID in fstab tried using LABEL instead, or even /dev/xxx. Every time it hangs. I've googled this endlessly and not found a solution. So don't ask why... since I seem to have tried every odd suggestion to fix this, I've lost track. There seems to be some consensus that whoever gave us plymouth laid an egg. Forgive me if I'm wrong, but did we need a better graphical boot if it breaks everything else?

I have a server that NFS exports the /home directory out to other computers. On the desktop they all work great, but on a wireless laptop, this is where the problem occurs. The wireless enables after the person logs in, rendering the NFS export /home useless on the laptops.Is there anyway to have the wireless enable correctly on the boot so that NFS can mount properly at boot also?I'm using Fedora 11 (32bit) with a wireless router that has a security of WPA-PSK [TKIP] + WPA2-PSK [AES]. I could switch to some of the older versions if necessary to get this working.

I've been trying to run Memtest86+ ,4.0 and 4.1, first from the boot option and then from a bootable CD but it will not run for some reason. I get to the blue screen where my system stats are displayed, but on the top right where the test should be running there's nothing showing. I'm at a loss and need to test my memory as 10.04 has some random crashing on my machine.

I install 10.04 on a Windows laptop using Wubi. It worked! However, I have no memtest86+ option on my menu. I am going to get some more memory soon so I would like to have that feature on my boot menu. Went through this article [URL] Yes, memtest86+ is installed, has the +x flag on the appropriate file, and all the pieces are present. Ran sudo update-grub and it shows it finding everything except memtext86+.
I'm at a loss at what to do now. If this was the old Grub, I suppose I could manually code in the memtest86+ line but since this is Grub 2, that wouldn't be a permanent fix.

Anyone know how to run memtest86+ from the Ubuntu 10.04 install CD without having to install Ubuntu? It used to be a menu option at boot, but now you just get the option to install or try Ubuntu. I want to test the RAM on an older system before I install.

I have Mac OS X on a second hard drive, and GRUB/BURG detects 32-bit and 64-bit versions of OS X. Problem is, my CPU isn't x86-64, so I don't need the x64 version. Also, I have to use the BIOS to select OS X, because GRUB won't boot correctly to OS X anyway. 30_OS_Prober detects them despite all my efforts. Is there any way that I can block /dev/sdb boot entries?I have FreeBSD on /dev/sda3 and GRUB won't autodetect it. It's under 40_Custom, but still won't appear.

I have a roughly 3-year old PC that I put together from parts (listed below) that has been running great with various flavors of Linux as the sole operating system. It is currently running Ubuntu 10.4. A couple of months ago, it started to have intermittent problems booting. The machine will hang before it gets to the Ubuntu "boot" screen with the dots that show progress as the machine boots. If I look at the power on messages from the BIOS, it fails at different points in the process - sometimes during the memory test, sometimes during the search for IDE drives. It fails about 2 out of every 5 attempts to boot. It sometimes takes 2-3 tries at booting before it actually works. Sometimes when it does boot, the Ethernet jack doesn't work and I see errors in syslog about there not being a carrier.
There are no syslog entries when the machine does not boot.The machine is plugged into a UPS. The UPS indicates that it is running at 13% of capacity at 123V/60Hz. I'm in the US.Once the machine boots normally, it will stay up without issues for days.I've checked the 4GB of RAM (I added 2GB to the original 2GB several months ago) using the memory testing application on the System Rescue CD and no errors were found.I've replaced the motherboard battery, which seemed to help for a few weeks, but then the problem returned.I've checked the hard drive for errors using the SMART diagnostics tool in System -> Administration -> Disk Utility and buy running fsck.The interior of the case is not very dusty and all the fans appear to be working.Are there things I can do to investigate and fix this issue other than starting to replace components - starting with the motherboard and the power supply?The parts of the machine:
CPU INTEL|C2D E6850 3G 65N 4M R - Retail (Qty=1, Price=$279.99)
CASE ANTEC|P180B BLACK RT - Retail (Qty=1, Price=$114.99)
MB GIGABYTE GA-P35-DS3L P35+ICH9 - Retail (Qty=1, Price=$111.99)

I have a box running Ubuntu 11.04 (natty). I have never run memetest before. Then, randomly, when starting up today, it ran memtest. Because memtest86+ is on a loop, it doesn't stop unless you stop it. So I tried restarting the machine - no good. It simply starts memtest again and runs the same testing loop. I cannot find any setting in the BIOS to disable memtest. how I can stop/disable memtest so I can USE my computer??

I started my computer up in ubuntu today and got an error while it was running through a system check. It said "Errors were found while checking the disk drive for /". I pressed F to fix it and a while later, instead of booting like it normally would, it went to the terminal.
It asked for me to login, and when I did, it said:
/usr/lib/update-notifier/update-motd-updates-available: 52: cannot create /var/lib/update-notifier/updates-available: Directory nonexistent

recently performed an upgrade to Ubuntu 10.10. when I rebooted, my GRUB menu showed only the memtest86+ option, rather than the usual options for Ubuntu, Fedora, Debian, Arch, and WinXP (which I haven't booted in a very long time, so I am almost 100% sure that it is not WinXP's fault. I was able to boot using a Live CD, and when I checked grub.cfg, all of my boot entries were still there. However, when GRUB itself actually loads, only memtest86+ is in the menu. I also checked that I can still boot by editing the memtest86+ option in grub so that it matched the entry for Ubuntu in grub.cfg, and it still booted correctly. However, I am curious as to why my GRUB is now forcing me to manually enter the boot entry on each boot. Here is my grub.cfg:
Code:
# DO NOT EDIT THIS FILE
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

Esteemed (K/X)Ubuntu'ers, I need some help. I had a Samsung HDD (Internal) that crashed, was a fault of the store that sold it to me and they went bankrupt. I thought I buy an external HDD (Western Digital Elements 1.5TB) and boot Kubuntu from there, so I still use the computer till I buy a super nice one after USB 3.0 hit the streets.
The problem I keep having by booting of the external HDD is that GRUB keeps saying Code: error: bad filename how to install Kubuntu on a external HDD and make it boot correctly?

I have been having trouble with one of my computers.It is a AMD 1800+ with 512 megs of PC2100 high density ram.I am running chrunchbang linux 8.10.2.The problems I am running into is programs freeze, slow way down, or quit out right.The screen saver looks as if it running in slow motion.I had read somewhere that bad memory could cause some of these problems. So I ran memtest86 from the boot menu.After it had ran for about an hour.It did one pass and it said I had about 300 errors.That is about I could understand from all the information listed.
What would be considered bad ram.What is an acceptable number of errors. I have 384 megs of low density (3x128) sticks that I can put back in the machine. Just don't want to dig the machine and ram out if I don't need to.

I need to check RAM on a server located in a data center several hundred miles away. So, I can't just walk over and boot to CD to run memtest86. Is it safe to run this while booted into the OS? Does anyone know of a knoppix pxe boot image? I can network boot to something...I just don't know what to network boot to.

I lost power during my Ubuntu update and when I powered back up ubuntu was broken. Now the stupid bit. My hdd was partitioned into 3 bits, vista os, data, and ubuntu. In vista I deleted the ubuntu part and merged it with the data part. Now when I power up my computer it goes straight to a black screen that says...
error : no such partition.
grub rescue> I have looked through the forums for an answer to my problem but to no avail. When I put the ubuntu live cd in and turn back on itjust goes to the same screen. I'm a novice to the world of computers and need any help you can offer.

I have a few machines set up to run off in the corner without monitors attached. I installed 11.3 (32-bit) on a couple of them and they run fine during setup but then I move them to the corner with no monitor attached and they won't boot correctly.
By this I mean they still run some apps I setup to run automatically from daemon scripts, but I can't ping or access the machines at all. It's almost like they aren't booting all the way up. Hooking a monitor up fixes this but I don't have enough monitors to keep these hooked up like this.
I have a couple of other 11.3 systems that are setup almost the same way but I put graphics drivers on those and they work with or without monitors attached. I don't want to have to put graphics drivers on those systems.

I have a desktop computer running Linux Mint 9 with the Gnome desktop (not sure what version -- though by default Mint 9 comes with Gnome 2.30). Last night I tried adding a panel to the desktop by right-clicking on the existing bottom panel and selecting "New Panel". Please note that I've already got another panel at the top of the desktop on the left side on autohide and no expand.
When I added another panel, it placed a normal panel on the right side of the screen without any problems. When I right-clicked on the new right-side panel and selected "Properties", I changed the orientation to "top" (where there was already a panel, if you remember). After that moment, it seemed like the entire desktop environment crashed. Everything was completely unresponsive -- the only thing moving on the screen was the mouse. I couldn't do anything with the gui, not even shut the computer down.
Since the gui shutdown wasn't working, I switched to a different tty screen, logged in, and ran a shutdown command with the option to reboot. The computer shut down fine, and when it woke back up, the same problem was still there: Nothing loaded on the screen except for the background image and the mouse, which was still able to move but nothing else. I have the computer set up to automatically log me in, so I know it's not crashing before the user prefs are being loaded...
After restarting it again and getting the same result, I switched to a different tty screen, logged in, and tried messing around with stuff to no avail. I did notice, however, that the computer was becoming evermore sluggish, and something printed on the screen stating that a program had been terminated because of "not enough memory". It seemed like some process was consuming WAY too much RAM by itself or a program was accidentally forkbombing the computer. ...All because I added a panel...?

I updated my server via SSH from another computer. I'm running Ubuntu 10.10 on my old laptop. I updated it at the 1/3. But now i experience problems! Since the update there where Radeon driver updates which made Ubuntu not to load X. [URL] You can see the update @ 1/3. The computer is a HP 6715s. As I can remember there is a Radeon X1250 in the computer. How can I get the old version working again without reinstalling?

I have currently installed the ubuntu 11.04 natty narwhal edition through the wubi installer alongside windows 7. I wanted to just check out what the kde environment had to offer differently from the default desktop environment which is gnome unity environment.
I installed the kde environment using some sudo command given by google. After using kde environment for a few hours, I just began to feel, I liked the default gnome environment better (in classic mode) as compared to kde as I was more used to the former.
So I uninstalled kde with another sudo command which I got by googling. At the final step of the uninstallation, I admit I am not sure whether what I did was right or wrong. There was sth related to 'daemon' that popped up eventually and I chose yes for that and kde was uninstalled successfully or atleast that's what I thought.
But to my horror, when i tried rebooting my laptop to ubuntu gnome, the blue coloured kubuntu logo was popping once again and I had to go back to the synaptic package manager and delete sth called the 'plymouth' package to remove the kubuntu logo.
Now after doing all these, when I tried booting ubuntu, I was not able to get to the gnome login screen. The screen was just stuck with the ubuntu logo and the process bar blinking and gnome never started.
When I pressed the Esc key to check out what was happening from behind, I could see that some processes were being checked and there was a [ok] after everything and there was a [FAIL] next to "starting CPU interrupts balancing daemon". And the terminal screen ended with "stopping system V run level compatibility". I am not sure if this might be the root cause of blocking the boot-up. But I couldn't get a screenshot of those intermittent terminal screens as I was not in a position to type in any commands such as fbgrab which can be used to grab a screenshot of the terminal screen.
Eventually after intense googling, I figured how to manually configure gnome to start up. I pressed the Cnt + Alt +F1 as soon as the white ubuntu logo popped up and after logging in into my ubuntu account through the terminal interface, I typed in the following things:
And then voila I got the gnome login screen. I temporarily heaved a sigh of relief. (by the way I saw something flash quickly on the terminal moments before it went to the gnome login screen like "you need not init this way or sth"..I just couldn't catch sight of it properly as it flashed only for a few moments)
But I am not satisfied. Obviously there might be a way to set this problem right isn't it? Kindly someone pls throw some light on this issue. I want gdm to be automatically activated during boot. Its a big pain to manually configure it everytime I boot. Is it possible to do a windows restore to set the ubuntu right? But I saw in some forums mention that something called the boot.ini will botch up if we perform a system restore in win 7.
Method that does not involve uninstalling ubuntu and reinstalling it. This is because I have done a lot of tweaks, optimisations and installed lot of apps in it. I do not have a system image backup as well. So it will be a nightmare to do all these things over and over again. The mistake or rather the drawback from my side is I just have my laptop alone and do not have another standalone desktop to experiment with linux.
