Ubuntu :: Can Only Boot To Memtest
Feb 1, 2011
Downloaded ok and the terminal did it's unpacking and updating thing, then it said I needed to reboot.So I did, and now I can only boot into memtest.I've had this before and the solution was to hold shift down at boot to force grub to appear, then pick a kernel and set it as default in startupmanager once ubuntu had loaded.
But no dice this time, I've tried holding the shift key down (using USB and ps2 keyboards) but I cant make grub appear - straight to memtest every time.

I did updates that came up automatically, and now when it rebooted, I can't go in to anything except memtest. I held shift to see the menu and it still only showed those. I can't loose my data so reinstalling isn't an option for me. Right now I'm using the CD to boot to this. I can see my data on my HDD and its there, but I don't know what to do in order to make it boot to the OS partition (Just switched from Windows 3 days ago).

Shut down as normal last night, no major changed yet after booting this morning my computer went straight into memtest86+. After finishing, and i rebooted, it did it again. So, i held shift to get into the grub.

according to this [URL] I issue this command sudo chmod -x 20_memtest86+ when I do that I get this error chmod: cannot access `20_memtest86+': No such file or directory I know it is something simple but, I don't get it.

I have a machine that was running 10.10 and I updated it to 11.04 and now when I reboot I am taken directly into memtest. Any attempt to hit esc during boot is ignored and no matter what I just go into memtest. Here is /etc/default/grub from my boot drive
Code:
ubuntu@ubuntu:/media/c8e24038-87b7-4a9a-87e0-11de250e3f4b$ cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
[code]....
I am booting now from a 10.10 USB stick and I can access my boot drive so if I need to change stuff I can.

I ran grub-customiser to set default kernel, and saw the GFX mode setting, thinking "Hey, my monitor is native at 1440x900! I'll use that!" ...Didn't think about how the GFX card isn't initialized at that point, so my res is limited to 640x480... So the first problem was a system hang at the grub menu, with "Input Not Supported" displayed on the monitor.I changed the GFX mode back, and ran update-grub, and with a grin on my face, I rebooted. The grin went away fast, when I saw that none of the kernels showed in the grub menu, and I have only the two memtest entries. It appears that, while all the files are still intact, grub is not seeing the kernels. I had an idle partition of about 13 GB on hand, so after trying all sorts of things, I did a clean install on the little 13 GB partition. Still no dice, after doing an apt-get purge grub etc etc etc on my main Ubuntu partition, to make sure that the new grub was running. I still have only memtest, even though I can open the /boot directory and see the kernel files. I tried going into the grub command line and starting manually, but tab-complete does not suggest any of the kernel files, and tells me that the files do not exist, if I type in their full names.

I am having problems installing linux on an old PC with the hard drive shredded, old CD drive, old 1 GB RAM card. I want to make sure the problem is not that the memory is partially bad.I recall that there should be some way to get the BIOS to test the memory overnight, but couldn't find this mentioned in the books I checked or in my notes. I believe that the motherboard is made by ASUS, if that helps. When I power on and hit the delete key, I do get some BIOS options, but memtest is not mentioned.

I just finished an install with 4 OS's. DOS, XP, WIN7, and UBUNTU. They work fine no with problems. However, the menu entry to run memtest does not work, However on my other system it works. The failing system is an i7 and the working one is a Core Duo. Both have a lot of ram. The Ubuntu os was copied with GPARTED. So it is identical.The menu.lst was a copy/paste job and then the HDxx's modified as needed. Please take a look and tell me where I went wrong.menulst.txt

Bought computer 11 months ago, immediately there were problems. What would happen is, when I logged in after a long period of shut down, the system would BSOD. Then I would restart and everything would be fine, until the next time I shut down for a long time (8ish hours) and got back on. I sent the laptop in (a couple times) and they eventually replaced the RAM and the BSODs went away. This is all on Windows 7 (well started on Vista, switched to Windows 7).
I recently set up a dual boot with Windows 7 and Ubuntu 10.04. I'm experiencing crashes on Ubuntu (the whole system just freezes, can't operate mouse, keyboard, or anything) and the behavior is similar. When I log on after a long period of shut down, the system will crash, but if I restart (actually I have to wait 10 minutes before I restart, if I restart immediately it will crash again) then it is fine, until the next period of long shutdown.
So I'm thinking it's bad RAM, so I downloaded Memtest and am testing each of my sticks (they are each 2GB) individually in the same connector thing (don't know what it is called, whatever the sticks attach to). The test for the first one passed with flying colors. However, the second one is having problems. On test #2, the memtest repeats itself, continuously looping through 0-32767 errors on the right side.
My laptop is an Asus G50VT
The 2 most interesting lines...
Highest Error Address: 000fffffffc - 4095.9 MB // does this make sense? 4095.9 MB on a 2GB stick?
Test 2: 32767 // the 32767 loops back around to 0 and repeats

Using Ubuntu 10.10 and Win XP - dual drives booted by GNU Grub version 1.98 +20100804-5ubuntu 3 Every now and then, a "Memory Test (memtest 86+)" and a "Memory Test (memtest86+, serial console 115200)" line are added to my Grub startup screen. This causes Grub to start-up a different line than I have set to default. (Ubuntu vs. Windows, etc.)
1. How do I edit the start-up Grub to remove the "memtest" lines?
2. How do I prevent this from occurring?

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.

It seems that the canonical instructions for making a bootable USB flash drive that runs memtest are at:
[URL]
However, after following them to a T, I boot up the new machine and get:
"could not find kernel image: linux"
Do I need to set up a lilo.conf first?

In a new PC I had constantly BSoD. I tracked it down to bad memory modules and took them back to the shop.Specifically the RAM was Corsair. Anyway they said they will do test on memory to confirm. They did tests and admitted the RAM was faulty and gave me a replacement. At this point: originally I bought 2 kits of 4G RAM. One of the kits turned out bad. They gave me a replacement, it does not seem to be exactly the same, though. In any case, I became causious and as soon as I got them I put them in the PC and run KUbuntu memtest. It started showing thousands of errors! (Again!). I removed the new kit and run the test again. No errors. I swapped the slots I put the memory modules and also no errors. I can not understand now. Is the new RAM kit bad or not? Does the slots I place the kits matter?

I've been getting some system freezes when running blender on a new system (using about 1/2 my 8GB memory, AMD Phenom II x6 1090T+default AMD CPU cooler, ECS A880LM-M motherboard, Corsair 1333 DDR3, 2x4GB). PS voltages (measured off MOLEX plug) 12.05VDC and 5.2VDC. Tried BIOS resetting defaults. I'm trying to narrow down the problem with the MEMTEST v4.0. It gets through all tests fine until test #7 (block move) and starts throwing a ton of errors, and about 2/3 of the way through that test it says "unexpected interrupt, halting CPU0." All the listings say "28dbbd11" (this varies from run to run, except the 'Stack:' listing seems to count up from that number). I've tried unplugging one memory module and then swapping them as well as their positions. Same result always: block moves throw errors, followed by halting CPU0. To me this suggests the motherboard or the Phenom II. But I don't know how to test these. Can someone give the next step in diagnosis? I did find this link, but I'm not sure how it differentiates between my error and something specific to either the MOBO or CPU:

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

Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.

Have just installed 9.10, again, many failed attempts previously.Cannot get to boot up and show menu on dual boot with Vista initially,However when I delete the grubenv file the system boots ok and works fine.But does not show the grub menu to choose boot up choices.Got the information to delete the file on some posts elsewhere about booting problem, and tried a longshot and got into Ubuntu for the first time from trying to install now for 3 months!The problem is the file grubenv is created each time so on subsequent boot ups the sytem fails to boot again.The Grub version is 1.97 beta 4, most up to date for Karmic I think, I have seen a version 1.98 but dont think its for Karmic?
Is there a way to modify the grub.cfg file to stop this problem ( all posts say dont touch this file??Or install a script to delete the grubenv file on shutdown as a workaround for me, (I have no idea how to do this whatsoever, I'm not familiar with linux at all)I did read that this problem was fixed/patched in Grub version 2, but dosn't seem.so on my system afetr I updated it when I got into Ubuntu.I couldnt find the patch or fix, I got the information I am on about from this post:URL...It seems to say it was fixed or patched by Colin Watson reading through, but I don't really understand whats being said or how to get the patch on my system if indeed there is one?Sorry for being a bit thick about all this, its a bit beyond my brain now, hope somebody can help out as I have enjoyed my brief bit of fun in Ubuntu.

I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.

I have a netbook running Windows XP as standard. There is also a recovery partition which came from the factory.
In the past I installed Ubuntu (I think 9.something) from USB key and all worked fine. However my XP became corrupted and I needed to do a repair on it. After this, Ubuntu became removed from the boot select menu.
Since then, Ubuntu has become updated to 10.04, which I now cannot install.
The Live CD tells me there is a "file IO error" and simply stops installation at around 70%.
I did manage to get into Ubuntu from a Live USB using Wubi. However when I chose to install Ubuntu to a Harddrive, the option to "install side by side" was missing.
After reading on the forums, I did a chkdsk /f on Windows and tried again. Now my liveUSB does not show a boot menu!
When I select to boot from USB stick, the screen goes blank with a flashing cursor. Ctrl+alt+dlt reboots.
I'm really lost here! It seems when I fix one problem, another problem arises!
Also when trying to instal Ubuntu within Windows, the process goes through to 100% and asks me to reboot. When I do so, the option for Ubuntu does show in the boot menu. However when I select it, I get an error "Windows boot failed: file wubildr.mbr and status: 0xc00000f - something is corrupt".

I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

I am building a 10.04.1LTS server. I am putting the /root filesystem into a Software RAID1 partition. I want to keeo my /boot partition outside of RAID.Is there a way to have a boot partition on both sda and sdb so if one drive fails the second boot partition will work away - or should this be kept in with RAID also.

I've been a long time Windows user, but I've started a small firm and because of lack of funds, I've decided to install Ubuntu on my company's PCs.I have 8 PCs in total - 6 of them with Intel CPUs, and the last two with AMD CPUs. I bought the extra two computers because I've managed to find an extra two people to work at my company, and AMD-based PCs are cheaper so I've decided to buy them instead of Intel.Long-story short, I've installed Ubuntu 9.10 and boot time takes about half-an-hour. After the computers finally boot, USB hardware doesn't work at all. I was forced to buy PS/2 keyboards & mice and they both work fine after the PCs boot.I don't know what's causing this delay.I've enabled Cool 'n Quiet from BIOS.I've tried several instructions like editing the /etc/modules file.I've installed cpufreqd, tried to configure it, but it didn't work.I've check the CPU stats and my CPUs are running at 800MHz. I can't believe nobody managed to fix the 800MHz problem as I've noticed it's quite common among AMD Ubuntu users. I think I've tried almost anything that I've found on this forum.I can't keep asking my employees not to reboot their PCs. Both Chrome/Firefox crash a lot on Ubuntu so they're forced to restart their computers.The computer specs are: AMD Athlon II X2 240 dual-core @ 2.800MHz, 2GB RAM, 500GB HDD, etc.

I was upgrading our lab's dhcp server to Lucid and it totally died. I have it running on a Debian recovery cd right now. I ran into a bug in gtk which I seem to have fixed, but now I have more serious errors. If I boot without a CD, I get dumped into a busybox shell after the machine fails to boot. From the live CD, I tried dist-upgrading again and it dies trying to build and install rsyslog with a broken pipe error. I am at a loss as to what to do from here short of reinstalling (which is the last option as this server has a lot of custom configs on it)

I recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?
