General :: Want To Remove LILO On Boot Sector
Feb 24, 2011
Here's the set up.
1. Got an EXISTING LILO... VL 5.8 (/dev/hdc3)
2. Installed VL6.0 and installed its own lilo on Boot sector (/dev/hdc13)
3. Everytime I choose VL6.0 in my existing LILO (/dev/hdc3) it still goes to VL6.0's LILO. The question is, how can I remove the VL6.0 so if i choose this on my existing lILO. It will just boot straight.
VL6.0 LILO:
root:# cat /etc/lilo.conf
# LILO configuration file
# generated by 'liloconfig'
# Start LILO global section
boot = /dev/hdc13
#default = linux
#compact
#prompt
#timeout = 0 .....

upon adding the installed VL on the existing LILO.. (btw i have not installed its LILO on the installation setup) since i know that i will just add it to the "existing" LILO the error above arises upon doing the lilo run command.$adding Vector6.0 etc.FATAL : Boot sector of /dev/hdc13 doesn't have a boot signature.i have tagged the /dev/hdc13 bootable via CFDISK. but same problem arises..

I cannot boot into the Windows 7 partition, which I guess is /dev/sda1. I have Slackware installed on /dev/sda2 which boots fine, my /etc/lilo.conf looks like
Code:
/etc/# Start LILO global section compact

I recently installed 11.3 on an external drive. After adding some software in yast (searched Kernel and checked every option), I was prompted to reboot but the no boot sector found error came up. Tried reinstalling with the same result. Grub is boot loader

Old Setup: I HAD Ubuntu 10.04 (Fresh Install) and Vista. These were booted using GRUB as installed by Ubuntu.
New Setup: I have added Slackware. This has replaced Grub with LILO.
Problem: I have setup liloconfig so recognize each OS. Vista works great, so does Slackware. However, when I select Ubuntu: "Ubuntu is in Low Graphics Mode". Followed by a system crash.
Question: Ideally id like to simply stick with LILO. Is there a simple way to achieve this?
Note: some, on other sites, have suggested installing GRUB from Ubuntu LIVECD, however I am concerned, since I have no boot disk for my Vista that I might make it impossible to boot Vista if a GRUB problem is encountered. So ideally, id like to simply figure out how to work with LILO since it already works with Slackware, and Vista.

Slackware's lilo runs from sdb1. I installed ubuntu studio on sda3.
I can't boot it from lilo.
Code:
boot = /dev/sda
image = /boot/vmlinuz
root = /dev/sdb1
abel = Slack64-cu-sdb1
read-only

Just installed Slackware 13.37 and am trying to get dual boot to work properly. I have edited /etc/lilo.conf to point the Windows section to what I believe should be the correct partition (/dev/sda2) Here is the relevant section
Code:
# LILO configuration file
# Windows bootable partition config begins
other = /dev/sda2
[code]....
I have mounted /dev/sda2 to /ntfs-c as suggested during install and when I browse through there I see the files from my windows setup so it is in fact the correct partition. When I load Windows on boot, however, it is pointing to the recovery partition (/dev/sda1).

I've run Debian on my laptop for quite some time now with no problems. I installed Slack to a new partition created in the free space of my hard drive, and I thik this was my mistake: I let Slack automatically configure the MBR with lilo (can't remember - I should stop operating on the MBR at 4 AM.) Now Slack runs just fine, but upon bootup I would like to be able to boot either Debian or Slack, but instead I just have a Slack splash and the only option is to press enter to boot Slack.
Code:
I believe sda1 is the root directory of my Debian install.
Code:
In the above table, sda10 is the swap I created for Slack and sda3 is the root directory for Slack. All other partitions were there before (my initial Debian install).
Thus my partitions are apparently intact and visible by the MBR (is it correct that the MBR holds the list of partitions on a disk?) but for some reason I don't have the option to boot Debian at all - just Slack.
I have a feeling this is a LILO/GRUB issue, but I don't know where to start.
EDIT: more poking around seems to reveal that it is the configuration of LILO that is the problem. Observe the following output:

I have one distro installed, LILO as the boot loader, and i wonder if it's possible to duplicate the lilo entries with an option which executes some script or command during, or after the boot.Actually, i installed a Slackware + autolaunching virtual machine, but i have two VM, so i need to autolaunch one of them. May i choose it from the very beginning ?

I currently have XP installed on a NetBook (Samsung NC10), and would like to run Fedora on it. I'm currently looking at putting Fedora onto a flash memory card to test it works OK on the hardware, before installing it to the hard disk. The problem I've got is that the boot sector is occupied by WDE software (TrueCrypt). Will this pose a problem for dual-booting XP with Fedora, or will GRUB move the boot loader in the usual way?

I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.

I just installed squeeze from a usb key. Installation went flawlessly but now I need the usb key to boot. Nothing happens if I let the bios boot from the HD or if I force it to do so. When it boot up from the usb key, the HD is read and the boot up sequence continues. Grub seems to be installed in /boot/grub. I imagine that I have to copy the usb key boot sector to the HD but how?

I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.

My old Dell Inspiron 9300's CD Rom is no longer working. I've written the files to my 8GB USB device, and attempted to boot from it. Whenever I try, I get this "No boot sector on USB device". I'm also using Mac OS X to make the USB drive.

i installed slackware 13.1, previously i had slackware 13, i made the following partitions:
[Code]...
everything went fine until i rebooted slackware after installation. lilo didnt boot at all, just a black screen. i booted with the DVD, and checked the lilo config file. the contents on lilo looks fine, just like any other lilo on google. for example i have this: boot = /dev/sda
i installed lilo on the MBR., i then changed this to boot = /dev/sda1 , on root and nothing same thing lilo always complains at the end: Partition entry not found , but how come , /etc/fstab shows all partitions are mounted ,( i am doing this in KDE environment). i reinstalled again , same thing. I also get a warning: video doesnt not support VESA mode, i changed to vga = normal again it complains that video doesnt support vesa even when i set it to normal, (note that i am running lilo after i made those changes, even rebooting , and same thing happens.
when i installed lilo, it let me choose video modes for the boot screen because lilo showed that my video card supports vesa mode, but then it doesnt boot at all. did slackware 13.1 changed so much that my laptop is no longer supported?? everything was fine with slackware 13 or is it because slackware needs a separate /boot partition, if so how come i just installed slackware 13 with just / and swap?

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 been running a dual boot system with Windows XP and Ubuntu 10.10 64 bit with the dual boot selected by Grub (placed y an Ubuntu install).
Recently I have installed Window 7 Home on a spare disc. My Bios allows me to select which disc to boot.
The Win7 installation has overwritten the boot sector on the WinXP/Ubuntu dic so that it is now not bootable.
I can sse all my Ubuntu files with a Live Linux Disc, so I can get all my files back.
Is there any easy way to re-install Grub or should I just do a clean install of Ubuntu, perhaps to a blank partition?

I'm writing a C program that reads the boot sector of a USB disk. (it is mounted as /dev/sda1). I'm able to read the sector, by the calls code...
The problem is when I wish to write. I use the call:
bytesWrite = write(fd, buf, 512)
The 'write' returns the value of 512, which looks as if the write was successful, yet
when I read again the /dev/sda1 device, I see that no writing was actually made.
Can anybody tell me what do I need to do in order to allow an actual write to the
device?

Is there a way to run the lilo command from the ubuntu 10.10 boot cd? It doesn't get the directories right, as it has / mounted as the ramdisk memory file system, and / can't be demounted since it's busy. I can install lilo in the ram after booting from the cd with sudo apt-get install lilo. Mounting / to my sdb1 partition (where Ubuntu is installed) does not get the proper "maps" for the lilo command, since the cd ramdisk / takes priority. I prefer not to use grub, as I wish to use windows vista's bcd(edit) as the main boot selector and it won't boot grub from bcd to a partition; at least I couldn't get it to work in 11.04. I got lilo to work from the vista's bcd menu in 11.04, but had many glitches. Windows allows this type of proceedure from its recovery cds.

before i start messing with anything, i figured i better ask before i get myself into trouble. ive been searching around and havent seemed to have found anyone with a setup similar to what i am trying to do. here's what i'm doing:
i have two identical 20gb drives, hda and hdb. hda1 is root. i am setting up either rsync, dd, or cpio to copy hda1 to hdb1 possibly once a month with a cron job. I just want to have a monthly backup of root in case hda1 ever fails. no, i do not want to use fakeraid or mdadm to set up a raid1 array, just want a monthly backup. should hda fail, and i need to set hdb as first boot device in bios, and boot off of that, i need to have a working lilo on that drive as well. if i copy the boot sector with lilo off of hda onto hdb, the boot= parameter in lilo would still be pointing to hda, and not hdb.
so is there a way to set two multiple boot drives in lilo? if not, how would i go about installing a separate lilo on hdb with its own conf? i was thinking something along the lines of modifying lilo.conf on hdb1 to point boot=/dev/hdb and root=/dev/hdb1 and chroot to hdb and run lilo -v? and if i do the above, and i do boot off of hdb1, will everything work as it should? what about needing to modify fstab for / being on hdb1 now?

I just installed Slackware 13.37, and it's my first version of Slack.
After installing, Grub was still installed on my system, but since it is supposed to boot an OS that's no longer on the hard drive by default, it drops to the Grub Rescue prompt every time I boot.
How can I boot Slackware from grub, or get lilo to boot my system instead of grub?

I have a question that is really probably a lilo question, but here goes. Can you use lilo to boot different linuxes on separate hard drives. Like this.
/dev/hda1 - Slackware 13 with lilo in MBR
/dev/hdb1 - Puppy linux
Here is my lilo image area:
[Code]...
Boots Slackware ok, but when booting puppy it screws up and seems to be printing the boot messages for the Slackware kernel on hda1. Now, how do I tell lilo to find the puppy kernel?

I have a laptop that I have installed Slack-current on, I am currently using the usb image to boot from. Windows7 is installed on sda2 and sda2 has been marked with the bootable flag, I would like to use lilo to boot the laptop do i install lilo to sda or to sda2?Will win7 still be able to boot using lilo as the boot loader ?
Another issue i noted during install is that the kernel panicked using the dvd to install with an error stating it could not read from the booting device, I eventually used the usb-pxe install to load the system however since 13.1 i have not been able to load a system using the dvd.

I run 64 bit ubuntu 9.10. I recently rebooted my computer with a flash drive plugged into a USB port. My question is, could I have got a boot sector virus because of this? What are the symptoms of a boot sector infection? After the incident, I scanned the flash drive with clamav and it didn't detect any viruses. Also, in the BIOS, the hard drive is higher up in the boot sequence than USB mass storage drives. These two things suggest to me that a boot sector virus is improbable. But, recently, when I tried to boot into ubuntu, I got an error message saying that /dev/disk/uuid<some characters here> didn't exist.
Is this a symptom of a boot sector virus? So, I ended up re-installing ubuntu and I believe grub was written to the MBR. Will this have erased any boot sector viruses that were on my system? Can a boot-sector virus affect linux too? How can I check to see if I have a boot-sector infection? I also have windows xp on my computer. For some reason, windows xp isn't letting me install any updates, but this has been going on for since before the above incident with the flash drive and therefore I don't think that is due to a boot sector virus.

I was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.

I am a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.
So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.
Does anybody know? Or better yet: what exactly do I need to do a manual grub install?

Been away from linux for a few years thaught id come back and give it a try again. I have Win7 on sda and installed 11.4 Ubuntu on sdb. Grub2 Over wrote the boot sector for windows so windows wouldnt show in the boot menu. I repaired that after some research and then tried it again with 10.4 LTS version of Ubuntu. Same thing. Now I've fixed windows boot sector a second time and im ready for round 3. Any hints on how to get grub2 to boot both OS's? Ubuntu 10.4 is still on sdb I think I should just need to re-install grub2 But how to do it without Killing the windows boot sector?

I have three disk in my system. One SATA (250GB) and two SCSI (73GB) disks. The Two SCSI disks were installed originally and RHEL3 is installed on it. The SATA disk is installed a few years later with RHEL5. As you can see below, the boot sector is still on one of the SCSI disks (sdb1).
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 236545184 15259760 209075624 7% /
/dev/sdc2 68539636 4578792 60479160 8% /users
/dev/sdb1 101089 26847 69023 29% /boot

tmpfs 2025916 652 2025264 1% /dev/shm
How I can move the boot sector from the SCSI disk (sdb) to the SATA disk (sda) without losing data and without re-installation?
