Red Hat / Fedora :: How To Edit Grub - Unable To Find Boot Record
Oct 12, 2010
i installed ubuntu inside windows but someone instead of uninstalling it directly deleted the ubuntu folder inside windows ,thinking that the partition will be deleted. but when i restarted the system and command prompt came and said unable to find boot record and i couldn't boot windows as well and a grub prompt came like grub>, then i inserted the windows boot cd and repair the boot record error but my problem is , instead of doing this way, can i do so by grub prompt directly without using winidows cd.
I want to set up a web server on a PIII machine with about 800MHz processor and just under 500 megs of RAM. So how would I go about configuring Fedora 12 to do this? I've tried the small spins and I just don't know how to configure it so it will install properly. I was able to get the Gnome spin on it but when it booted I couldn't get through the log-on screen. I have an AGP NVIDIA Geoforce 6200 video card. I'm wondering it that's it. The only Linux distros I could get on the machine was Puppy and Debian. Puppy did not edit the boot record very well. Debian went on there with very minor issues, but edited the master boot record very well so that I can dual boot to WindowsXp HE. I also tried to put Centos on there but the Live CD is not installable. I have to make an installation CD from the DVD Package. Anyways, as far as Fedora is concerned, I just want a utility, light weight spin that has web-server, mail server, and eventually MySQL. Other wise I'll have to commit treason and use the horned Debian as my savior in this battle.
Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen....nothing works except Ctrl+Alt+Delete....system reboots showing successful daemons shutting sequence. 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?
I'm trying to set up some shares on this pc and every time I try to edit the /etc/exports file I get this error. I get the same error when I try to edit /boot/grub.conf file or any other files. Does not matter what editor I use. I'm running f14.
I have 2 harddisks 1 tb and 160 gb. In 1 tb fedora is installed. In 160 gb windows is installed. 1 tb is the master. 160 gb is not being detected. How to edit grub.conf file to edit the menu?

Debian if my first OS and i want to dual boot Fedora12.Ok i installed Fedora12 and choose not to install the bootloader(gonna use the one Debian installed)What i'm tring to do in Debain is edit my /boot/grub/menu.lst Here is what i have
I've been using squeeze for a year or two now, on a PC dual booting with windows xp. Not long ago I thought that, as it's now become the stable release version, I'd do a fresh install, which I've been trying to do with the first two dvds. The installation proceeds as expected, up to and including setting grub. However, although grub saysthat it has detected windows xp, and I tell it to set up the dual boot, the computer on reboot goes straight into windows xp, with no on-scrteen option shown for choosing debian.
I have recently installed Debian alongside Vista on the same boot menu using the GRUB booting device. Only problem is, I couldn't boot Vista at all any more, so I removed my Debian installation from that drive. But the GRUB boot record persists, I don't have the Recovery disk to restore my old system, so I have to find a way to manually remove the GRUB track and put the old record in its place. I assume there was a copy made of it by the installation program, now my only problem is to find that file and copy the content back in place (at the address at the very beginning of the drive) all that by using Linux code, since that is all I have left. Being new to this game, I have no idea how to begin writing the right command for a job like this
I think I managed to corrupt my master boot record, or have a very intractable problem with Grub.
I'm not sure how I did this, but my desktop will boot Ubuntu fine from a USB, but every time I try to install it, the install seems to go fine, but when I finish the install and the machine tries to boot the OS from it's hard drive, it does not work. The monitor does not get a signal and it just goes to sleep.
I tried posting here to resolve the problem before, tried everything on this thread: [URL]
But nothing worked.
I have even tried running the system from a USB, running a "shred" command for the hard drive and then reinstalling - my theory was that the shred command would destroy all the data on the hard drive anyway, and allow a "clean" install from whatever was corrupt on it, but no luck - when I installed Ubuntu on the hard drive, same problem.
I'm not clear where the problem lies now, I'm assuming there is something up with it's master boot record, but there are no partitions on it's hard drive and I started with a completely blank, unformatted drive.
A few days ago I installed my first Linux product, which is Debian 6.0, and I installed the GRUB booting device on my main boot record, as it was suggested that it was a harmless step to take. Unfortunately, some quirk in my system made GRUB believe that I had XP when in fact I have Vista, so the options I have now are to boot Debian or to boot XP which is not on my computer. In other words, I have to get rid of GRUB now, but I'm realizing that he's not such an easy customer to kick out. I have moved my Linux installation to another drive, but the old GRUB always stays in place, and my Vista is stuck there frozen for eternity. So after considering all kinds of possibilities, I have come to the conclusion that the easiest way to restore my original boot record would probably be to find its backup copy that I assume the installation program made, and to copy it back into the right address at the beginning of the disk. I don't have the Vista recovery CD, so I really have to do this manually. So now my questions are these: did the installation program make a copy of the boot track, and if so, where did he put it and under what name, and finally, what command can I use from within the Debian terminal, which is now my only tool left, to copy the content of thesaid file into the first 512 bytes of the hard drive? I know that would be a simple matter for any serious geek, I guess I must be a little rusty. Anybody feel up to it?
At the moment I have a list that has: Debian 6.0 + kernel information etc Debian 6.0 same again (Recovery Mode) Windows XP Home Edition etc when all I really want is: Debian 6.0 Recovery Mode Windows XP you used to be able to just edit menu.lst but it seems not now.
Im finally deleting vista from my disk, but as I am game addict I will re-install it afterwards just for games. Now I assume that will overwrite GRUB, so how do I restore boot record and at same time keep my grub config?
Is there a way to re-install grub on the master boot record of a hard disk using a live cd?If so will i have to configure it?I'm trying to install a linux distro on my ao751h(with poulsbo ) but i after installing it i can't boot.I get an error 15 or a flashing underscore.I have already tried ubuntu,debian,mint and slackware(LILO isn't compatible with poulsbo).Also,does anybody experience problems with the ubuntu 10.04 and 10.10 installers or is it only me?when i choose the language and keyboard settings the installation stop as it is and i get a crash report.
I successfully installed Fedora 11 from the DVD iso. At the end, the installation program prompts me to reboot the system. But when the boot loader appears after rebooting, there are only the old entries.
I have 2 IDE disks and one sata disk. The first IDE disk is hd0, the second IDE is hd1. The SATA disk is hd2. In the setup, I selected hd0 to install grub. Fedora 11 was installed on the SATA disk (hd2).[edit] I forgot to say, that Fedora 10 is on /dev/sda and Fedora 9 on /dev/sdb
I just installed Debian on the unused part of my HDD. It did not pick up the other OS I have on this PC, but the installer said I could later edit GRUB to make the other OS boot again. I have looked around and done some searches with no luck.
I'm using HP Pavilion dv2108tx I have ubuntu and Win7 dual boot. The problem is every time I change setting to the BIOS there will be a new list of ubuntu boot came up and now I scroll trough the whole list. Is there anyway to edit GURB boot list.
I recently switched my laptop from Ubuntu 11.04 to 10.04.2, and during the process, I used GPARTED to partition the drive so that I could have both versions installed simultaneously while I transferred files and settings and such. A few days ago, I removed the 11.04 partition, formatted and added that disk space to 10.04's /home partition. However, when I boot up, GRUB still gives me the option of loading into the newer 11.04 partition with the newer kernels. How do I remove those options from the GRUB menu? I checked the Ubuntu GRUB help pages, but didn't feel confident that I could do edits without messing up the 10.04 boot settings.
I installed windows and haven't been able to boot to fedora since. Without a boot disk my machine complains 'BOOTMGR is missing'. If I use a boot disk to access grub on another linux partition (/dev/sda5) I can try to boot my fedora install using its old grub.conf settings. However this gives me the grub error:
Code: root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /boot/vmlinuz-2.6.29.6-213.fc11.x86_64 ro root=UUID=63608748-e626-4a3f-9232-c836524f606f rhgb quiet
Error 2: Bad file or directory type Darn grub thinks the file system type is ext2fs - this makes me think windows might have written something (perhaps its bootloader) to the first partition rather than the MBR.
I set up a dual boot system with Win7 and Ubuntu 9.10. Ubuntu is the first OS listed in the boot menu. I would like to change the boot order so Windows is first. Also after running a few updates I now have multiple boot items listed for Ubuntu that I'm sure are no longer needed. Having never edited Grub and searching through the forum, I'm asking help. I going to guess that I want to edit grub.cfg. If so, what do I need to change within the following information?
I'm dual boot with Vista(TM) and UBUNTU(tm) and ran out of space on Ubuntu partition:I booted Ubuntu 10.04LTS live CD and shrank the VISTA. It would NOT let me grow the extended partition? So now I have:
sda1 ntfs /media/TOSHIBA_SYSTEM_VOLUME 1.46GB sda2 ntfs /media/SQ004588V03 88GB sda4 ext3 THIS IS MY NEW PARTITION 15GB
I think my Natty 64 bit install is missing a dependency for gk, even though it shows up install in Synaptic. I have also tried using Start up Manager and the changes I make there don't show up after restarting either. I just want to change the default boot to number 4, Windows. Any suggestions are welcome, but I have tried all the ones I've found on this forum so far and none have worked, including editing etc/grub/default and saving with sudo update-grub. That's when I get a "gk not found" error.
I have win 7 and F13 installed on my computer but I am having trouble setting up dual boot so I can choose to boot F13 or win 7. I have tried to set up grub, how to install grub and set up a dual boot so I can use F13.
I have Ubuntu 9.10 64 Bit, and I also have Windows 7, and I want to make Win7 boot first and without having to manually choose it every time I restart, for my non-linux using family. I have tried the guides where it says you have to edit the "menu.lfg(or whatever it is)" and I don't have that file. I have looked, it's not there, the closest I found was "grub.cfg" and I can't make any sense out of it. I'm not unfamiliar with computers, I'm just relatively new to Ubuntu, and want to make the best out of it I can, I love it. I've tried going into GRUB, and and editing the Win7 Loader, but it doesn't work.
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.
I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?
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:
