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.
View 9 RepliesI'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.
View 6 Replies View RelatedI 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.
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??
View 1 Replies View RelatedI 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.
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

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'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.
View 1 Replies View RelatedHas Linux some mechanism to test memory online as a background job, flag bad memory as unusable and warn the user if memory is faulty? Much like running Memtest86+ on a little chunk of memory every nth minutte until all memory is tested and then repeat over.
Edit: I did not make it clear that I want such a service running in the kernel. A (peak) performance hit should be avoided by running the test in small steps and only when the system have some CPU cycles to spare
Edit2: I meant this as a Linux kernel service that scans the memory in the background. Not meant to be run in userspace but a routine in the kernel itself, perhaps in the memory manager to make sure memory are sane!
I am having memory problems on my old Compaq PC, and am trying to run memtest86+-4.20 to check it. I downloaded the source file, and tried a compile, but had the following problem:

how to get around this issue?
I have had no problems with downloading/installing updates and programs, and everything worked fine. Until memtest came along. It ran by itself (I think my dad made it the first boot option in grub), and now if I try to install any packages or programs, it will either say "Grub installation failed" or that any packages I tried to install failed. If I removed memtest, would that make it possible for me to install stuff again? Or is there a way to work around it?the main error report I get is: "E: memtest86+: subprocess installed post-removal script returned error exit status 127"
View 1 Replies View RelatedI just recently installed Ubuntu 10.10 on my computer. Everything worked fine at first and then I started to fix all things I wanted to have on my laptop, programs and layout etc. And then I decided to restart the computer to make all the updates and installations work properly on my newly installed Ubuntu computer, but then it seems so that everything just crashed. When I started to computer again a blue screen saying "Memtest86 v4.10" came up. It is some sort of test of the computer's capacity I think. So I thought, ok fine, it is probably really good to do a test like that after a new installation. Like, standard procedure perhaps. It took 1 hour and then it said that no errors could be found on the computer and that I could click ESC to continue.
I did that but then when the computer restarted this blue screen showed up AGAIN and started up a new test (the same one)!!! I can't open up Ubuntu, I've tried several times. What should I do??? Is my computer broken now????
I have a Wubi installation of Ubuntu 9.10 and am trying to upgrade to 10.04. The download of everything went fine, but it has stuck on the "installing the upgrades" part, about halfway through it keeps saying "Found linux image: /boot/vmlinuz-2.6.32-22-generic". It keep repeating this constantly. The status bar says "Preparing memtest86+" with about 14 minutes remaining.

I had ordered for a Ubuntu 10.04 CD on 27th. It's still not approved...can any of you say why.... I have received 3cds from ubuntu previously by ordering. It takes about 1-2 days to get the approval....why is it so late this time?

Second, I want to include the ubuntu-restricted-extras so they can immediately try it out and see that it also plays video/audio etc.

View 1 Replies View RelatedAbout two weeks ago I upgraded from Karmic to Lucid. The upgrade went fine, everything works wonderfull, except maybe for Wine but am still figuring that out.
What I find a bit strange is that on the boot-up screen (where I get the choice between the different OS's on my two hard-drives) I still see Karmic listed on the partition where I upgraded (see attachment: on /dev/sda1).
When I boot-up, I first get this message: Mounting: mounting none on /dev failed: no such device
This stays about 20 seconds on screen after which Lucid starts up and gives me the log-in screen.
Since today, I cannot start to X anymore. Grub loads, I let it start, then after a while screen goes black, stays black, puter not responding at all, screen goes to power save.
I can boot to safe console though but not start X there either.
So far I tried Memtest (no errors found) and apt-get update and upgrade. SafeX doesn't work.
I have an old laptop that I want to install Lucid Lynx on from a flash drive but when i try to do so all I get is a blank screen after I select the language and the option to install.
