I am trying to run Memtest86+ on my Linux computer. I use Grub 2, and Memtest86+'s core is located in /boot/memtest86plus/memtest.bin file.It seems to be pretty newbie error, but I can't find any documentation covering this problem.If I use linux16 instead of netbsd, computer just restarts without any error.

If at all possible I would like ot keep the GRUB loader and repair my situation.My slave drive has Windows 7. My master had Ubuntu on it. When it installed it added the GRUB loader.I replaced it with Fedora, but now the GRUB loader says it can't find the drive and bails to grub-rescue.If possible I would like to keep the grub loader. If I can't repair this, is there a way to uninstall it and reinstall it.

How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

Now i want to use grub to present a menu at boot so i can select an OS. Because I installed XP last it boots straight into XP. I've understood i should be able to do the following:
All goes well until the last step (grub-install). It gives an error stating that /dev/sda doesn't exist, which is correct; It doesn't. I do have the "device" listed outside of the chrooted environment.
My question is: How do I get /dev/sda available in my chrooted environment?
I installed ubuntu on my internal hard disk I experienced a problem with Grub and I just formatted all the Ubuntu Partitions and convert their format to NTFS to restore my windows (I have a backup) but now despite of I format all the Ubuntu's partitions but in the boot time, the grub exist and the grub apear I want to know where does grub exist? I installed ubuntu on the dual booter situation and it was ubuntu 9.10

"grub error> partition does not exist.

Due to a motherboard issue, I need to edit a parameter in the "etc/default/grub" file.
However, the problem is, that file doesn't exist.
Grub does seem to be installed, I can get into grub from the command line etc.
This is a fresh install of Ubuntu Server - 10.04.2 LTS
Brand new box, no previous installs of anything, no other operating systems etc.
Is there somewhere else that file could reside ? I tried find -name '*grub*' and got plenty of files, but none are the one that I need.
Is there someway to generate this file ?
I remember when installing from the CD it asking about grub, but I don't recall which option I chose, it was whichever one was the default.
This thing won't reboot right after power loss etc until I can edit that value... which at the moment seems to not exist....
Btw, I'm not a total linux noob but far from an expert, so I may need any answers "dumbed down" a bit.
EDIT (more info):
It seems that I have regular "grub" and not "grub2" installed... I'm assuming that is part of the problem ?
My version: grub-install (GNU GRUB 0.97)
Does this version of grub allow you to edit options etc ?
Specifically, what I need to do, is edit this value: GRUB_CMDLINE_LINUX_DEFAULT
I need to add "reboot=a" to this line.
Plan to use GRUB for multiple booting to select the OS but only with luck have I got it partially to work. Windows 98 and Puppy 431 O.K on first HDD but Puppy 421 on second HDD /dev/sdb1 stops at error 21.

I have recently installed Ubuntu Karmic on my laptop, which also has Windows 7. It now has GRUB, and I have been able to modify some settings via the GRUB command line. However, these changes are not permanent; they are reset the next time I load GRUB. I have seen many people trying to configure GRUB who have been pointed towards /boot/grub/menu.lst. I expect it would) I went to edit that file... and discovered that it did not exist. I am certain that I am using GRUB, not some other bootloader. Is there another possible way to configure GRUB, or somewhere else I might look for this file?
View 4 Replies View RelatedI have a dual boot windows XP/ubuntu 9.10 set up on one hard drive. Everything was working fine. The 9.10 install had been updated from 9.04. I recently had problems with the XP partition (XP basically collapsed) so I re-installed XP on the same partition it was on before. I then attempted to reinstall Ubuntu ( I decided I wanted a new 'clean' installation of Ubuntu as well). When I got to the partition function it refused to recognize that there is a Windows partition, or a previous ubuntu partition, but states 'No operating system installed' or similar, and offers the entire hard drive for installation. When I look at the partitions using Windows partition software the Windows and the ubuntu partitions are clearly in evidence. I have also tried to reinstall GRUB but it doesn't appear to exist.

View 14 Replies View RelatedI just got a laptop (DELL PP06S) from a friend set up on kubuntu. He told me to download and run the updates packages if I had time. So so did I and now the computer stops on an error at boot and I can't log in at all to type any command. The error message coming up is:
ata1.00: exeption Emask 0x0 SAct 0x0 action 0x6
ata1.00: BMDMA stat 0x24
ata1.00: failed command: WRITE DMA
[code]....
And it seems to try that action over and over but I never get to log in and type any command. I got told to check the drive cables connections, which I did but it made no difference. I also got told that I could try to start with an older kernel, I tried all the different kernels available in the GNU GRUB but no success. The different options availables are:
Ubuntu, with Linux 2.6.32-26-generic
Ubuntu, with Linux 2.6.32-26-generic (recovery mode)
Ubuntu, with Linux 2.6.32-25-generic
[code]....
From my understanding these are the new and older kernels, is that right? I had to do the updates in 3 times so I guess the kernel from before then isn't in the list anymore. Every one of them shows the same error message and no way to get a console. So I can't type any command. Though, I found out that I can type commands in the GRUB, is there any way to change the kernel from the GRUB? If so what would be the commands?
I have done the kernel compilation for linux-2.6.38.5 I have perform all the steps well ,once i am updating in /boot/ grub/menu.lst & giving command update-grub it showing this error
Code:
[root@localhost grub]# update-grub
bash: update-grub: command not found
I have install it also through
Code:
yum install grub
I gave this command
Code:
grub-setup --version
still same error ]grub-setup not found
I am learning Linux administration and I am new in this area. Currently I am trying to find out which drive has grub.conf file. Following commands giving me correct output (hd0,0):

I can boot the live CD and I have internet access with it, but I can not remember the terminal command to repair Grub. Can someone tell me this command?
A failed upgrade, from disk images, of Fedora 10 to 11 resulted in no GRUB bootloader main menu appearing on bootup (no WIN, no LINUX choices from which to boot). I am booted directly into the GRUB command shell...so, no WIN, no LINUX, nothing. And my understanding of GRUB shell commands is very low.I have 2 hard disks, WIN on the first, LINUX on the second. I believe GRUB Bootloader is on the first disk.Sadly, I have no external install media.An old grub.conf hardcopy indicates that root =/dev/sdb2, root (hd1,0), kernel /vmlinuz....olderversion...(relative to /boot),initrd /initrd...olderversion... (relative to boot). and WINDOWS on (hd0,1), with chainloader +1
I need to somehow get past this grub shell, and re-install/re-instate the grub bootloader, so it can boot normally.What grub command(s) must I use? I've played around with the commands, but with no success.I worry that if I can't resolve this, the whole machine may be useless.
Code:
grub-install -v
grub-install (GNU GRUB 0.97)
I loaded GRUB, and now when I reboot it goes straight into the 'grub>' command line. Initially GRUB had the root as (hd0,2), whereas the boot is on (hd0,1)...(hd0,2) is my '/home' partition, and (hd0,1) is my '/' partition... So on a bootup I ran...
Code:
root (hd0,1)
setup (hd0)
Now when I boot I still get the 'grub>' command line, but now the root is correct.
From 'grub>' I can type...
Code:
grub> configfile /boot/grub/menu.lst
GRUB will then show the menu, and I can click the listings to load them. All's fine, but why doesn't GRUB just load the menu.lst without my prompting? How can I automate this process of typing 'configfile /boot/grub/menu.lst' each time I boot?
