Software :: System Stops In Grub At: GRUB Loading Stage1.5 Error 18
May 3, 2010
My Server runs "fine", then I type init 6 for rebooting or some cron job initiates Init 6 and my system stops in grub at: GRUB loading stage1.5. Error 18 After another Ctrl+Alt+Del the system boots as if anything happened. this is why I doubt that it's an issue of too big HDD or BIOS.
When I try and boot my Debian computer I get the messages: Grub Loading stage1.5. Grub loading, please wait... Error 15 Is there any way of recovering from this - or is it simply a fresh install? I was attempting an upgrade from Lenny to Squeeze and despite a few hurdles it looked like it was all happening. Got the new kernel loading, and the new grub. It looked as though grub2 was working so I ran the grub-remove-legacy-support command (something like that) and now my computer won't boot grub or Linux.
I'm assuming the MBR on my harddrive is lost, however I don't know what state the partition is in. I'm guessing that maybe this has been lost as well. I tried a few tools from the Ultimate Boot CD but nothing here was able to re-install my grub or boot from any partition or even mount my file-system. I'm fearing the worst but would like it confirmed before I blow it all away with a new install.
I know nothing about this at all. I have never programmed a computer.. I loaned my tower to a friend who put this on ...now i have it back and cant get to my windows 98. all i get each time i boot is ...
GRUB loading ... error:no such disk grub recover>
I have tried ubuntu sec 8.4 recover mode and all i get is unreconized command.. i do not know how to set anything.. i have no disks for this not even the orginal windows recover disk.. is their anything i can do to get win to run as it use to??
I have an Ubuntu Jaunty server with 4 x 1 TB Hitachi SATA Hard drives and a 4GB IDE Flash Drive. I installed the root file system to the IDE Flash Drive and setup the 4 x 1 TB Hard Drives as a RAID 5 for the home partition (I actually allotted 3 Gigs on each drive as swap space as well). My problem occurs however when I restart my computer after the server installation. Grub doesn't load fully and I am left with a "GRUB_" message on the screen.My root partition is ext3 and I have also tried the same configuration with a boot partition as well on the IDE drive to no avail.
I installed Windows XP and then Ubuntu on the remaining disk. However, each time I go back to windows, windows decides to destroy grub and it stops loading, then I have to use a rescue disk and do a grub-install again. It's annoying to have to do this everytime I go to windows. Is there a way to avoid windows to destroy grub? Or install grub on a place windows cannot touch?
I successfully installed fedora 12 the other day, got it up and running fine. Yesterday I installed windows 7 on my second partition on the drive (dumbest thing ever, I know). What I forgot is that windows can't handle not being in control, and that it would replace my bootloader (grub). "No problem" I thought. I booted a live usb that had grub-install on it (which has worked for me in the past). The drive which needs grub on it is /dev/sda, sda1 being the partition with /boot on it.
So I do the following in the live usb:
Code: mkdir /media/fedora mount /dev/sda1 /media/fedora grub-install --root-directory=/media/fedora /dev/sda
But after a few seconds I get an error message saying that "stage1 not read correctly". When I go into the drive I can see that there is a file /media/fedora/boot/grub/stage1, and the device.map which grub creates appears to be correct (/dev/sda corresponds to hd0). Going into the grub terminal and running "root (hd0,0)" then "setup" gives a similar result (complains about not being able to find stage1).
On another forum someone mentioned tyring "depmod" before installing grub, but that didn't work for me.
I have a number of questions about the detailed mechanics of Grub. My first question is hopefully simple. Lets say I have a separate /boot partition at (hd0,0), and install Grub's Stage1 to the MBR. The BIOS knows to load and execute the bootloader residing in (hd0,0)'s MBR because the BIOS is configured in CMOS to do so. But then how does the copy of Stage1 that lives in the MBR know to find Stage2 in the /grub partition of (hd0,0)? If Stage1 was written to the MBR of (hd1) and the grub partition was in (hd1,3) my impression is that Grub handles that seamlessly. I would guess that when Stage1 is copied into the MBR by grub or grub-install, it must have a built-in parameter value that essentially says "find Stage2 at /grub/Stage2 in (hd0,0)". But I haven't found an explanation of this in the Grub manual nor in the webpages I've look at so far.
I soon found out that Suse 11.1 would no longer boot from boot.ini (using bootpart) because the boot process now brings up PCLOS (in /dev/sda6) rather than Suse 11.1 sitting in /dev/sda5. No problem, I thought, I'll boot from the Suse install DVD, use repair, and away I go. Wrong. After grinding, it started mentioning about generating something for sda13, which is my last partition. NTFS! So I bailed before it got too far. I even tried "rescue" option on the DVD, command prompt, and grub commands to reinstall via "setup.
Then I tried to use Super Grub Disk (.97xx) to reinstall the PBR, stage 1 and stage 2 loaders. Didn't change a thing. So then I used Grub4DOS and got into my Suse 11.1 installation using this in its menu.lst: title openSUSE 11.1 - 22.214.171.124-0.1
Worked fine, and is now my (only) method of booting to 11.1. So obviously it's bypassing stage 1 and 2 files, using it's native Grub4DOS code. But then I tried Yast-Bootloader to reinstall Grub's files. No difference. Then I used the advanced part to "write bootloader code to disk" No difference. Even tried "propose a new boot scheme" (or whatnot) no difference. After looking at all this, I've come to the conclusion that the PBR code in sda5 is scraunched, and/or stage 1 code (although it's still the original date), or stage 2 (which definitely had a new timestamp of when I committed the fatal error by executing PCLOS's "install.sh".
So my question is this: How do I do a good COMPLETE re-install of Suse's version of the grub files? Because, for sure, grub commands like "setup --stage2=/boot/grub/stage2 (hd0,5), and variations thereof, certainly aren't doing it? My reasoning is that I should make sure that all the boot files get restored/confirmed as "originally installed by Suse".
So I have 2 ide hdds but whenever they are both connected, grub gets stuck at GRUB loading stage 1.5. how can I resolve this problem? both are Maxtors with ext4 fs. primary is 20 gb and secondary 80 gb. Jumpers are set to cable select. Boot order in bios is correct. (primary first, secondary isn't in the list at all)
I been running both OS's for a few months now with no major problems besides wireless internet issues. Today, however, as I go to boot my laptop up, the Dell logo loads with the F2 and F12 boot and setup options which both work. Directly after that though I get the message "GRUB loading. Symbol '?' not found. Aborted. Press any key to Exit." then it repeats when I push a key, and then it tells me to press F1 to retry, F2 to go to setup, or F5 to run diagnostics. It passes all the tests in diagnostics. I've tried booting off of the ubuntu cd I used to load it initially with no luck. So I'm stuck at either that error message or in setup but I can't go any further, and it does not change anything when I tried to boot from the cd.
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.
I'm using Arch with the latest updates and I'm pretty sure this is a software problem.Basically about one out of five times my system freezes at "Grub Loading Stage 2". Whenever this happens, I usually just reset my box with the reset button and it will boot up just fine the next time.I originally put it down to being a defect in my hard drive which is probably three years old now at least. However, last week I bought a brand new 1.5TB drive. I removed my old drive and am using only my new one. Same problem.I Googled for this problem and found a bunch of posts with the same issue as I'm having, yet all of those issues are with people that dual boot with Windows. I don't. I only have Arch and no other OS on my system. I then tried reinstalling Grub and that doesn't seem to have solved it.I'm hoping someone can help me out with this. I hope it's not a hardware problem. Any help is VERY appreciated as this problem makes me worry that something worse is going on.
I have a dual boot system with Windows 7 and Ubuntu 9.10. I booted into Ubuntu and started the process to upgrade to Ubuntu 10.04. When it was all finished, it restarted and attempted to boot into the GRUB load screen. However, I get this message:
I applied all updates to my Kubuntu 10.04 installation, and shutdown and went to bed. Booted up this morning and found: [code]...
This error is returned if the module load command is used before loading a Multiboot kernel. It only makes sense in this case anyway, as GRUB has no idea how to communicate the presence of location of such modules to a non-Multiboot-aware kernel. lets re-install GRUB. So I booted up my live CD, and ran:
My laptop is running Fedora 12. I installed BackTrack 4 onto an external USB hard drive using a LiveCD. Now when I boot my laptop. I get this: GRUB Loading stage1.5. GRUB loading, wait Error 21. I never touched anything with my internal drive. When I was reviewing what partitions the installer was going to format, the swap partition for my internal drive (Fedora) was set to be formatted even though I did not specify this. Fedora never used to show GRUB loading at all. Screen was blank until Fedora starting loading. Maybe this means that this is a copy of GRUB from my BackTrack disc? I ran 'fdisk' to look for anything suspicious and under /dev/sda1 (internal drive, boot partition) it says "Partition 1 does not end on cylinder boundary."
I'm using an Eee netbook so i have no CD drive. I've used Linux for about a week. Someone else installed it for me using their flash drive. If I need to use a flash drive to install I will need info on how to install to a flash drive. I had it set up so i could choose windows or ubuntu at start up. logged into windows to play a game and all it brought up was.
GRUB loading. error: no such partition grub rescue>
I have a CLEVO laptop and it currently has Windows 7 installed. I now want to create a separate partition to install Ubunutu 9.10 64bit. I attempted to install this and the install part worked fine but as soon as I rebooted all I seem to be getting after the BIOS is 'grub loading'. I get no other error messages and am stumped on what the problem is. It also meant I couldnt load windows either but I fixed this by loading the windows cd, running repair and then fixing the MBR which another thread mentioned. Once this was done windows loading up ok. I have checked nearly every setting and it has made no difference. I tried reinstalling 9.10 but came up with the same problem. I am not sure what I did in Windows may have caused it. I have a 320gb drive and I shrunk it using disk management as I know the ubuntu will see this free space and install the OS onto it. Should I have left this and let 9.10 create some space automatically during install?
I installed opensuse 11.2 64bit on my external hard drive with the idea that this way the two OS would be completely seperate and I could just use suse when I felt like it. Everything boots fine for both OS when the hard driv is plugged in but when it is unplugged I can't get past a boot screen which says: Grub loading stage 1.5 Error 21 I have seen on another forum a fix using the windows install disk but I no longer have this. Is there some other fix I can use to make my laptop portable again.
I had win7 on my laptop. Before sometime I install Ubuntu 9.10 and it worked fine. Bur later that I resize the partition using third party software. Now when I restart the system it is giving me an error GRUB Loading error: unknown filesystem grub rescue> I am not able to access the harddrive. I am very new to ubuntu.
I went through the procedure to install Ubuntu 9.10 alongside Windows XP. The installation completed without complaint. But when I reboot the PC I get the error message "Grub loading error: no such partition...". and the keyboard is dead. I am using a Sony vaio PCG-FR215H laptop on which I have fitted new HDD and CD-drive. I carried out the installation by first booting up a live version of Ubuntu on a USB thumb drive and then clicking on the 'install Ubuntu' icon on the Live Ubuntu desktop. (I coudn't use a Live CD to install as this fails for some reason). I regained use of Windows XP on the PC by booting with a Windows 95 boot floppy and typing "fdisk /mbr". So, does anyone know what might have cased this grub error? Also, are there ways to try and fix the problem manually. I.e. can I get a copy of good versions of the files that are likely corrupted and then replace the stuff that I will have written over when I did the "fdisk /mbr"?
The follwing message appears when i start my computer (loaded with ubuntu 9.10 and windows) "grub loading error reading". i am not able to proceed further. and the part that baffles me the most is that i am not able to boot from the live cd as well.
