Ubuntu :: GRUB Lost Sight Of Windows XP?
Sep 1, 2010
I did a dual boot install of Ubuntu 9.10. After that, when I rebooted my Windows XP was gone? I did update-grub and still nothing. I popped in the GRUB Super boot Disk 2 and browsed around, I think i found it but it says "Error: Invalid Signature". Iv googled and havent found a solution to this yet.
I booted off a XP CD into the recovery console, it sees my Windows partition and lets me get into it and browse all my files. So I know its there. I then tried fixmbr then fixboot and now all it loads is my Recovery Partition. I booted up SuperGrubDisk again and same results, it just sees my Ubuntu. I reinstalled grub and back to square 1. Then I tried a checkdsk /r and tried it all over again. Nothin'.
I have some encrypted files on my drive using EFS....i guess it would be ok to loose them, but I put a lot of work into them..
how I can "wakeup" my XP again?

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 installed Ext2fsd from windows XP because I needed access to a text file on my ubuntu install. However, it didn't work because the drive is ext4 and all it listed was the root folders (/home, /var etc..) nothing any deeper.
I closed the app and continued working in windows.
Today I went to start my computer and it loaded the grub-rescue> prompt. I immediately tried to run "help" to find out what happened, however, grub reported the command as unknown.
I then ls and got a partial listing of the partitions.
Code:
(hd0) (hd0,5) (hd0,1) (fd0)
So what do I do? How do I recover my linux partition? If the partition is bad - then how is the bios able to find the grub-rescue> prompt?

I dual-boot ubuntu 9.04 and windows 7. I recently reinstalled windows, and it wiped grub-legacy off of my MBR. Reinstalling grub shouldn't be tough, right, especially with clear instructions? Anyway, I can't get anywhere with the official instructions here: [URL]. The first issue is that the current live CD has no program "grub" in terminal. I dug up an old live cd, but I couldn't get anything with the directions:
Find where Grub is. If this gives a few different answers then you will need to find the correct one, perhaps by trial-and-error.
find /boot/grub/stage1
That command didn't find anything, nor did some similar commands found on google.
So I'm really at a loss. What should I do?
-Can I install Grub 2 on my MBR? Will that work with 9.04?
-Can I access my 9.04 install, copy files to Windows, and then just format the partition and clean install 10.04?

Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.
Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.

I followed the instructions from this post to reorder my boot options. But somehow I was stupid enough not to copy the windows entry, as indicated (I was mainly following only terminal instructions and such).Now I have a grub menu without my Windows 7 entry, please tell me there is a way to restore it.

I just installed Fedora 11 (I installed over the Fedora 10 installation I had already installed)..
-Before I would have Grub give the choice of Fedora 10 or Windows (Where Windows would load the Win Boot loader for my options of Windows 7 and Windows Vista)
-NOW: I have the same options.. But when i select Windows (It loads the Recovery partition) instead of the Windows Boot Loader...
Here is my fdisk -l
Device Boot Start End Blocks Id System
/dev/sda1 1 192 1536000 27 Unknown
Partition 1 does not end on cylinder boundary.
/dev/sda2 192 5414 41943040 7 HPFS/NTFS
Partition 2 does not end on cylinder boundary.
code....

I have just updated to 10.04 on my Dell Insperon 8200 laptop, and all seems well with Linux.My problem is that although it shows in Grub Windows XP will not load. I just get a blank screen with a flashing cursor.I have tried to grub-mkconfig and grub-update, both of which reported successful results.However on reboot I still get a blank screen for windows.This was not an issue with 9.04 and 9.10.so I don't think it is the machine.

I had a working dual boot Ubuntu 10 and Windows 7. Anyways long story short, I got it working again but have lost the boot option for windows 7. If i run fdisk -l, I get the following.
root@support-Latitude-E6400:/home/support# fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
[code]....
I installed gparted and can see that windows 7 is installed in dev/sda6. In another forum, i read that someone had to edit their menu.lst so i did with the following.
title=Windows 7
rootnoverify (hd0,6)
makeactive
chainloader +1
When i try to boot from windows 7, i get the following error. Error 12: invalid device request. How can i get my laptop to boot from windows again?

I'm running a clean install of 9.10 on a crispy new pc (Packard Bell I-extreme) I've connected my pc via HDMI to my Samsung 5 LCD tv (source is marked/named 'pc') by means of an NVIDIA.The problem is that the x screen is too large for my tv. I see the 'working area' but the top and bottom taskbar fall of the screen.The current settings (which I of course double checked) worked when the pc was connected to the lcd via VGA cable. X Server settings and TV resolution are set to the same values...(1920x1080)

I keep finding the same fixes on the web and they are not working. What I have/what I did: I have a dual boot PC. HD0 was XP. HD1 Kubuntu 10.04. I upgraded XP to Win 7. This jacked my Grub up, now all I can load is Win 7. I don't see the Grub menu anymore. I've been trying to reinstall Grub using varoius web pages like: [URL]
They seem to all be telling me the same thing but not working. I boot into a liveCD. I have to sudo apt-get install grub then I can do sudo grub. I follow the instructions:
sudo grub
> root (hd0,0)
> setup (hd0)
I get "Error 17: Cannot mount selected partition".
Now if I'm understanding this right the reason for that is. HD0,0 is my first HD first partition (which is Win 7), and grub doesn't like windows. I tried swapping it out so it reads:
sudo grub
> root (hd1,0)
> setup (hd1)
I then quit and reboot. Win 7 loads. I don't see Grub.I am using 2 separate hard drives?

I am a linux noob and have been searching for a couple months to a fix for my problem but now I just need I have two hard drives. One with vista and the other with ubuntu, storage space, and some other partition. I was dual booting windows and ubuntu jaunty jackalope then one day I decided it would be fun to upgrade to 10.04 so I did. When I tried loading windows from grub it just showed a blinking cursor forever. And while attempting to fix the problem by adding windows to the grub menu.lst file it dissapeared from the grub options.

Login in problems:
I was trying to fix the brightness on my toshiba T130 Satellite laptop and found these instruction [Note: I did not try XRANDR option]
If backlight control doesn't work with the 'XRANDR' option above, use this code...
Safe the file, run 'sudo update-grub' and reboot.
Credits: https://bugs.launchpad.net/ubuntu/+s...id/+bug/392948[/INDENT]http://www.linlap.com/wiki/toshiba+satellite+t130
However after running these instructions and rebooting my laptop I lost the GUI, and do not know how to get it back.
If it helps the loader screen with the 4 dots has gone slightly skewed, and I've downloaded the most recent update changes.
I can get GUI through recovery mode and running it in failsafex, but I don't think this is a good solution.

Today I was forced to reformat windoze and of course lost grub so I can't boot ubuntu 9.10. I found two suggestions in previous posts which didn't work. One suggested using the install disk as a rescue disk and as root run grub. I entered sudo grub and the cmd was accepted but the cmnd grub was not found.
The second was to sudo grub -install and again grub was not found. Both these suggestions were for a win 98/mandrake installation.
Do I have to reinstall ubuntu? If so there is a problem in partitioning. Setup sees there is already an ubuntu os on the disk. In fact two of them. I forget why, but I reinstalled ubuntu and ended up with two in the grub menu. I was advised not to try to repair grub and didn't. Now I have two and it thinks I want to put the third one side by side, or erase and use the entire disk. There was a third choice but I forgot already exactly what it was and didn't like it anyway. If I erase and use the entire disk, won't I lose windoze? If I put them side by side I will then have three which which will waste disc space. The discs aren't that big being only about 10gb. I don't think I want to waste the space with a third ubuntu.

Just upgraded to 9.10 on a laptop with dead Vista which I lost when I moved over to UBUNTU some time ago. Never any problems but when fiddling at boot up tonight I accidentally selected to boot up the Vista loader which went into the Vista recovery, and since then the laptop only opens up the Vista Recovery, ie it does not go to the Grub. Any ideas on how I can get to boot UBUNTU again?

I want to know about grub. Let start with the explanation of grub. I am using Ubuntu 10.04. Yesterday when I installed widows7, I lost my grub. Every time I tried to install windows running on Ubuntu machine, the grub is lost. Why is it so? How can I restore it (for Ubuntu 10.04)? Can any advance setup be made while installing windows, so that the grub is not lost?

I have accidentally started the recovery OS of my netbook, and messed-up grub. I can start the Netbook from a live CD, but I do not manage to restore grub to anything useful. Below the outcome of the Boot Info Script I have found in the forum:
Code:

============================= Boot Info Summary: ==============================
=> Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #5 for /boot/grub/stage2 and /boot/grub/menu.lst.

When I netinstall debian squeeze an asus netbook using using Unetbootin usb stick, at the end I am asked if I want to install grub on MBR. I agree, yes, but on booting I find that the netbook has not grub. I go back to usb stick that stole my grub and I use it to boot. I go to sunaptic and install grub, still nothing, the netbook won't boot without the usb stick.

i have lucid lnyx installed as my main system and added natty on a seperate drive. after installing, the new grub detected lynx & i was able to boot into each without any problem. after doing some tweaking on natty (changed run level), it didn't boot properly so i reverted to the old config via rescue disk. after rebooting, the old grub menu didn't show & it loaded lynx automatically.
i tried the suggestion from another post changed the hidden menu and updated grub but it didn't detect natty (below).
