I couldn't get 10.10 to boot (live or after install). I was able to install and boot 9.10 normally. Then I ran upgrade to 10.10 and I started getting the same problem trying to boot as with 10.10 disk. I found I could boot with 2.6.32 left from 9.10 but it will not boot 9.6.35 kernels. On a normal restart when automatically trying to boot the latest 9.6.35, I get this message before switching to an unresponsive black screen with no further hard drive activity:
GRUB loading

Incorrect command

I have been searching for a solution and so far have not found anything that worked. I'm a pretty basic user so I'm not sure what is going on.
I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.
I seem to have determined a few other things about my "only gets as far as a GRUB command line" problem:To recap, sda3 (GRUB hd0,2) is the main Linux partition; sda9 (GRUB hd0,8) is the boot partition.GRUB is 0.92.Installation was from an 8.04LTS live CD (at least, that's what the envelope says it is)/"/boot/grub" (i.e., "/grub" on sd9/hd0,8) contains a "menu.lst" file. I modified it (had to do a "sudo gedit" from a command line!) to (1) comment out the line that hides the boot menu, (2) change the timeout from 3 seconds to 90, and (3) add a menu line based on my succesful manual IPL of DOS.
It still boots to a GRUB command line. If I do a "configfile /grub/menu.lst," a boot menu comes up. DOS will successfully IPL, but Linux still gets a "no setup signature found," (ditto for "recovery mode"), which suggests either a bad kernel, or a kernel that's too big for the GRUB to handle.Why would it be finding its way to grub, but not finding the boot menu file?Why would the live CD come up just fine, yet the GRUB and kernel it installs fail?
I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).
However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.
Question: Why haven't the newer updates shown up in GRUB for booting purposes?
Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?
How can this be changed? The new kernels do not show up in Start-Up Manager either.
I'm a very new Linux user, so speak slowly and don't use big words. I installed Karmic from the Live CD. It is the only OS in use on this system. I then upgraded to Ubuntu Studio using the instructions found on the wiki.
On bootup, I get a brief message stating "GRUB loading" and then the system automatically boots to the generic kernel. No GRUB menu is ever displayed. I would like the option to boot to the real-time kernel, but I have no idea how to edit the appropriate files. I've done a fair amount of reading on the subject, but I find very little information relating directly to the real-time kernel, and so I still feel like I'm too green to do it without messing something up.
Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.
I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?
A recent kernel upgrade broke nvidia and the network card. I figured out how to get the grub boot menu, but am having trouble figuring out how to set the default kernel to boot. I believe there used to be a file called /boot/grub/menu.lst that one could edit, but it doesn't appear to exist now.
I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.
I tried to update to 2.6.31-20 kernel but I think I messed it up, because when I click on it in the GRUB it starts to load but then it goes back to the dell boot up screen and I have to use the older one in order to get onto ubuntu. Is there anything I can do to fix this?
I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?
I know that error 15 means "file not found", but not how to figure out which file it is or how to point correctly to it.
I have tried to install the system on partitions on two separate disks, with the same end result. on the original disk I had some trouble getting through grub install, but on the other disk there were no indications of trouble during setup. can this a problem with the MBR on the first drive?
I have one drive connected by PATA, the rest by SATA, will SATA1 be (hd0)[grub] and /dev/sda [linux], is it the PATA drive, or some other means to determine this without examining the make and model of each drive?
My Slackware boots using the huge kernel. I am not using LILO; I am using GRUB from the extras directory on the DVD. I followed the tutorial @ [URL] up to the point where it discusses modifying LILO. My /boot/grub/menu.lst reads, in part:
# Linux bootable partition config begins title Slackware Linux on (/dev/sda7) root (hd0,6) kernel /boot/vmlinuz root=/dev/sda7 ro vga=normal # Linux bootable partition config ends
This boots the huge kernel. What changes must I make to the above menu.lst entry to boot using the generic kernel?
The first is I seem to have 3 GRUB installs. So whilst I update the one from my live session, the change does not appear in the boot up menu. I had installed 10.10 from a CD into a different partition (sda6), but that will not boot, so I have just deleted this and done another grub install and update. The kernel I am using has just been updated from 10.04 to 10.10 too, and it is this that I use and the Grub I have been working on (sda5).
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

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

I have tried the testdisk/update-grub method, but it didn't work.
So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?
I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).
The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.
I am looking for a way to configure grub to remember its default boot item under kernel updates.
Possible Duplicate:Make grub keep its default boot under kernel updates.I have just installed Linux with my windows 7 pre-installed and i got it working fine. Since i use windows 7 more than linux, i would like to have "Windows 7" option on the top of "Linux" option.
"When i have turn on my computer, the first thing i see is an Option asking me whether i want to use windows 7 or Linux and there's a countdown timer below it which is 10seconds countdown and if i don't select it on time, it will automatically select the first choice which at the moment i've got Linux pre-set as my first choice."
I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
I was installing sqeeze i386 on my laptop VOSTRO 1400 and got this the 'grub-pc' package failed to install into /target/. without the GRUB boot loader, the installed system will not boot.
I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.
Has anyone tried encrypting the boot partition to prevent the kernel from being modified. Iv tried following this but I'm running into issues when building. [URL] Im using the source from bzr checkout [URL] Last time I tried I screwed grub and it wouldnt boot.
I performed an upgrade via the Update Manager from 9.10 to 10.04 LTS and it seemed to go flawlessly. However, now I cannot seem to be able to remove the old Kernel from 9.10 in the package manager. It does not even show 2.6.32-21 as installed but it still shows the old Kernel in Grub. I did a sudo update-grub but it was to no avail.
After upgrading Maverick (perfect!) to Natty, I was unable to boot into anything. (kernel 2.6.38). However, through much PITA, I was able to boot into an older kernel. (2.6.35). I completely removed 2.6.38, rebooted, reinstalled it and ran update-grub. However, 2.6.38 is no longer available no matter how many times I run update-grub, and the only option left is 2.6.35. In my humble opinion, the Natty upgrade experience is rubbish. (blank screen, total PC hangs, boots into a blank screen with only a blinking cursor, NVIDIA official driver not working, bootable only into older kernels etc.)
I'm running Hardy 8.04 LTS 64bit. The Update Manager updated the kernel and then asked if I wanted to use the local version of the grub menu. The boot menu was getting so long I edited it to shorten it. Other options were also offered, like the builder's version, but I chose the local version and since then the new kernel doesn't show up in the boot menu. Sudo update-grub doesn't restore it to the menu.
How do I undo the local version of the boot menu so I can see the newest kernel?
