Ubuntu :: Repair Booting With Commands On Grub Rescue?
Oct 10, 2010
i have using ubuntu for 3 days with no problem i have 3 operating system vista,7,ubuntu vista and ubuntu on c: drive today i want to use vista for something and when i open it on ubuntu boot menu my laptops recovery try to recover and just give an eror like:EROR with 200 punto when i restart computer i just saw eror: no such partition Grub rescue> command screen i have no recovery dvd and ubuntu cd now i left them to my friend so can i repiar it just with commands if ubuntu is demaged because of recovery screen on D: partition i have win7
i just start using ubuntu i dont know any thing about it
my ubuntu installation has stopped booting after i deleted and again created one of my partitions (not the ubuntu partition but my data partition). but now when i switch on my netbook it says: error: unknown filesystem grub rescue>
i used gparted live to resize. this is my disk partition structure:
before doing this, my ubuntu partition was /dev/sda7, the swap partition was /dev/sda 6, and the data partition was /dev/sda 7.
I had windows 7 and I just wanted to try ubuntu and I am totally new to linux, however, I installed ubuntu 9.10 using wubi and it was fine when I boot it asks me for windows or ubuntu no problems. Then it asked me to upgrade to 10.04 I agreed and installed it. After installition restrting it gave me this grub thing I don't know what to do I googled it but I couldn't fix the problem please help I need my computer soon.
Also I tried but I couldn't boot from windows or ubuntu cd.
this may help: if I printed "ls" it gives me "(hd0)"
I had a problem with my grub (system displayed "unknown filesystem" and then the grub rescue prompt). I then used a livecd of ubuntu 9.04 and ran fsck for a while (closed it in the middle). Grub then worked. But when i select ubuntu 10.04 it goes to the purple screen and stops there. There's some error before loading the purple screen.
I created a new partition in Windows Vista which, after rebooting, screwed up Grub. I believe that I need to reinstall Grub and everything should be fine, and I remember reading the command to do this on this forum, but I can't find it. When I boot, I now get a black screen with white letters instead of the Grub boot menu. It says something about "Minimal Grub" at the top and gives me a prompt that looks like this.
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?
I am trying to install my laptop in a triple-boot configuration with Fedora 10, Windows XP and Windows 7 beta. I did already installed them in that order. This is how it is layed out on the harddisk:
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 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:
Upgraded from Ubuntu 9.04 to 9.10 via upgrade manager System is AMD 64 Have dual boot with XP on seperate hard drive
Then the wheelspin:
Seem to have knocked out GRUB as normal loading screen does not appear anymore. Worse, I think I accidently installed grub to something labelled SDC5.
Cannot get anything except the "grub rescue" prompt. I'm not sure if using the LiveCD (9.10) can help. Have tried a few prompts from other threads but just ended up with mud splattered all over the place. I'm gathering I need to load grub, but can I do it using any grub rescue commands?
Yesterday I partitioned my hard drive with kubuntu netbook remix and windows 7. after a few hours and reboots i turned on my computer and it said Grub loading. unknown filesystem rescue grub> It looks like allot of people have been having similar errors recently with windows 7.
So I wanted to get rid of ubuntu 10.10 on my HP pavilion dv6 laptop as I wanted to make some hd space. Its a dual boot with windows 7. I deleted the ubuntu partition and expanded the windows partition to fill the whole hard drive again. When I restarted my laptop I got the "error: no such partition. Grub rescue>" message.
I tried inserting my ubuntu 10.10 boot cd but whenever I boot from the cd I get the exact same grub rescue error. Is it possible to remedy this situation from the error? I am currently unable to download a windows recovery cd so I'm stuck in the grub rescue page unless its possible to fix this mess from the error prompt.
but I know a fair amount about the OS. I really like openSuSE, and I was trying to install 11.2 on my laptop, completely blank hdd. It installed just fine;I used the default options (the partition scheme was /boot, swap, root, /home) and started thesktop without a hitch. However, when I restarted, my BIOS would not even recognize an OS on the hard drive. I was also unable to boot using the installation DVD. I tried to use the repair feature, and I would either get a message saying that the boot loader was corrupt,d could not be repaired, or that the package database didn't match the version of openSUSE installed. I've tried re-installing multiple times, all with the same results. I have tried different partition schemes and I've tried different booting settings, such as enabling boot from root or /boot partition
I am using Fedora core 10. I have changed my partition size of Linux from windows. After I finished resizing the partition, I rebooted my system to the Linux platform. While booting it gave me an error: repair filesytem #1: I don't know what to do?
Im probally just being a noob here but for the projects sake I thought it would be good to identify this problem. I have an old advent laptop and I tried to install Opensuse from DVD on it. I followed the installation as normal but when I tried to boot it said some sort of check was forced and then I have to enter the admin/root password upon doing this I got the message system repair # in red. I have tried to repair the system through the installation DVD and tried re-installing it but I still get the same message.
I had an dualboot problem, after updating ubuntu to 10.04 my windows vista option in the grub of ubuntu was gone.Now I have installed windows 7.And the grub does not appear again, there is no grub at all.Now sombody told me I could fix or repair the boot record in windows 7.Does somone know how I can repair the grub in which I can choose between windows 7 and Ubuntu?
The boot sector somehow got messed up on a friends computer while updating. I used to know how to do it with the old version, but now that they've updated it and changed everything , how do you repair the boot sector from a live-CD with Grub 2?
I have installed windows 7 back to its former state in after foolishly messing around with some installation options in an Ubuntu install (this caused windows to disappear, and me to repair it). In *repairing* windows, I overwrote my grub file and the boot options for Ubuntu, so that it looks something like this:
Disk 1: Primary Partition - Windows 7 Disk 1: Secondary Partition - Windows 7 Disk 1: Secondary Partition - Free Space ( this is where I have Ubuntu installed)
How can I repair my grub file so that I can boot into my Ubuntu installation?
I'm going to be installing Windoze (because 3D graphics are still not there in Linux), but that will of course override the MBR. So how do I rewrite it? I just tried starting from the Fedora 11 DVD until it got into the 1st graphical screen, and then I tried to mount *any* of my Fedora partitions - I think it's made 5 of them (God knows why!!), but anyway,none of them would mount except /boot - kept saying "wrong fs type or superblock" etc. My plan was of course, to chroot my current Fedora partition, and then run grub-install, but of course I can't if the partition itself doesn't mount.
I've got myself the curious situation where, when I boot the system, I can get grub to start, but it always drops to the prompt.
I can run:configfile /grub/menu.lst
and this brings up the menu with no problems, and from there I can boot the system to either linux or windows. What I don't understand is why it wont go to the menu in the first place?As far as I can tell, grub/Kubuntu got confused when installing, as each of the hd#,# settings in the menu.lst have needed tweaking to let the system boot. (e.g. windows is actually hd0, but the original install had it at hd2. Likewise linux is on hd1, but the menu.lst had it at hd0). I've happily tweaked these to make the system boot, but would appreciate any help in convincing grub to actually load the menu without me having to use the prompt.
Ubuntu 10.04 was in small slave-disk, and I put other bigger disk same type IDE/ATA.In first start I get message: "no such device....., grub rescue."Anyway, I make installation in this disk and and now after start message is: "error: out of disk, grub rescue.So now I can not use master/XP and no slave/Ubuntu.
I started another thread about this to get help booting into openSUSE after Fedora rewrote my bootloader and deleted all other entries. I managed to fix it but I never did find out why the following commands caused my system to boot to the grub shell instead of the grub menu.
Code: grub root (hd0,3) setup (hd0) quit reboot
Can anyone explain to me why these commands caused my system to boot directly to a grub shell? It's as if there were no /boot/grub/menu.lst files for it to use, but after I got everything back to normal, the files were still there.
If it helps, this is how the drive was setup before and now, except Fedora was on /dev/sda4 and has since been deleted.
Code: Device Boot Start End Blocks Id System /dev/sda1 1 262 2104483+ 82 Linux swap / Solaris /dev/sda2 263 13316 104856255 83 Linux /dev/sda3 * 13317 14621 10482412+ 83 Linux
I have forget the root password of Red Hat Enterprise Linux 5. Please tell me how to recover it from the other linux account of the same version. I also want to know that after setting the new password did I have to repair the grub or grub will be as usual.
The new GRUB2 was supposed to configure itself from the old grub, but got the kernel image partition wrong.I have booted from Knoppix live cd, but need to write to system files. I have searched, and found several suggestions that apparently work on Win machines, but RO permission for root on Linux is a harder nut to crack.
I have a vista/ubuntu system. I tried to restart the computer into vista and it came up grub rescue. I did what someone suggested and typed in grub rescue> set prefix=(hd0,5)/boot/grub grub rescue> insmod (hd0,5)/boot/grub/normal.mod rescue:grub> normal Anyway that got me into a menu where the ubuntu server is. I chose it and it sends me into tty1 where it asks for my login My login when the machine used to come up log/pass was dan/mypass
but in the tty1 it says login incorrect. I need to get back into my server. I'm not sure why it's messed up. So how do I do it.
I'm a linux/unbuntu n00b and having some major issues here. I am new to using Ubuntu and have been experimenting with it on my netbook as well as kubuntu and a few others. I love the linux alternatives to Windows. It started with me running Windows 7 Starter along side Ubuntu. I was trying to resize my Windows partition and give Ubuntu more space. I managed to somehow delete the wrong partition, making a very careless mistake. Long story short, my netbook is stuck at the grub rescue screen and I have been searching the net for about 3 hrs just tonight plus whatever time I spent last night searching and cannot get this fixed. I've tried booting from the flash drive using Unetbootin and it will say "Missing operating system" before the grub rescue prompt and I did change my boot sequence. I've also tried using some commands in grub rescue and got various messages such as, no such disk, no such partition, cannot find "grub_xputs", cannot find C/H/S values...
I have a Gateway LT21 netbook with a 250gb hdd. Any help is appreciated. I realize this is a common issue and has been posted a lot but I have searched and my issue is on going and I'm guessing its specific to my setup.
