Ubuntu Installation :: Unable To Boot Into Windows After Upgrading Grub
Apr 10, 2010
I upgraded from grub to grub2 recently, and during an update of my system, it ran the update-grub command which prompted a window asking me where to install Grub. Since I didn't know what partition to install it to and the help suggested to install it to all if I was unsure what partition to install it to - I accidentally installed Grub to my Windows partitions (both the regular and the recovery console).
So now, I can't boot into Windows - the computer just hangs after Grub with a blinking cursor and I have to perform a hard reset. Is there any way for me to restore the boot record for the windows partition without having to reinstall windows from the ground up?! I can't use Linux for my webbanking and other important tasks, so (unfortunately) I need Windows back desperately!
I am new to Ubuntu. I recently upgraded my Ubuntu from 9.10 to 10.4 (64bit) since then I am unable to dual boot to WIN2K3 from the same HDD as my Ubuntu. I have ran some of the suggestions like: Sudo update grub and Testdisk both did not provide any errors on my partitions and my primary partition displayed in Testdisk was WIN2K3, now when I reboot and select it from the boot menu it just simply show a blinking cursor.
I am out of ideas and I need a solution to suit my configuration. I prefer not to re-install or repair any WIN2K3 OS. Can someone assist and let me know what you need from me to further understand my issue.
I recently performed a reinstall of ubuntu after mucking up my partitions, and I am running it dual booted with windows 7.
I recently performed a grub-pc update, but I didn't know what it was asking me to do during the process itself of updating the process.
It asked me at one point where to install grub, and I selected all my partitions because it suggested that if I didn't know. I think that may have damaged my windows section, which was also selection.
I've attached the output for:

Problem symptoms:
1) Weird upgrade error in apt-get 2) Unable to boot windows 7 3) Unable to activate proprietary drivers 4) Perpetually being reminded to restart
yestoday,after I upgrade,unable to boot windows xp. if I use grub ,windows xp can boot up.but now I want to use grub2, boot info script's results.txt is at below.

I had Vista loaded on my computer, then loaded the BRILLIANT ubuntu onto a second partition! This gave me the GRUB boot loader which is fine.My 2 points are;1. Can I change the position of the items in the GRUB loader so if no keys are pressed it loads Windows automatically?? (Its for my sons computer!!) Also can I edit the GRUB so its less complicated for him??2.I want to update his Windows to Win 7, free upgrade! This over rights the Win partition and will therefore get rid of my GRUB loader. When I have updated how can I get back the ability to chose between booting Win 7 and Ubuntu?? How do I get the GRUB back?
I had a dual boot system with 3 partitions, Windows 7 on one partition, and Windows XP on another partition and a Data partition. I decided to load Ubuntu 10.10 on the Windows XP partition.During installation I selection manual partition, and deleted Windows XP.after successful completion of Ubuntu installation "Grub" directly boots into Ubuntu, it doesn't show me the OS selection screen. After following some forum posts I did an update grub

I've just upgraded my server installation from 9.04 to 9.10. I'm running this as a Xen virtual machine. All seemed to go well until I restarted, at which point I got stuck at this point:
Begin: Running /scripts/init-bottom ... Done. mountall:/proc: unable to mount: Device or resource busy mountall:/proc/self/mountinfo: No such file or directory

My service provider is running xen-shell 1.0.79 running on Xen version 3.0.3-1, and after the seemingly-successful do-release-upgrade, uname -r reports ubuntu kernal 2.6.18-5-xen-amd64. Unfortunately, this isn't mentioned as a possible problem here [URL]
I installed Ubuntu 9.10 on Windows 7 system using Ubuntu disk partion option. Unbuntu works great but I can no longer access W7. Windows Loader Boot Option is in normal position as last selection of Grub menu but arrow keys do work. Acts as if keyboard is locked. System defaults to Ubuntu 9.10. How do I select Windows Loader Option
I had ubuntu 10.04 dual boot with win xp and I recently decided to upgrade windows to win 7. Once I did that I could no longer see the grub therefore I couldn't manage to boot into ubuntu. I don't know what to do, the installation is there because I never touched that partition
I've heard people have been finding that when they upgrade from 9.10 to 10.04 on a machine that dual boots 9.10 and windows 7, they can't boot windows 7 afterwards. There is a fix to this problem but I would rather prevention to a cure.
I had Ubuntu 9.10 and windows vista on my laptop and both systems boot normally throw grub but after I upgrade to Ubuntu 10.04 LTS windows is shown on the grub loader but if I selected it all I get is blinking cursor, Ubuntu boots just fine.
I recently installed Debian 7 on a dual boot with Windows Vista. Thus, when I boot the computer, I am prompted by a GRUB screen to select Windows Vista loader, Debian, and Debian (recovery mode). I would like to upgrade Windows Vista to Windows 7. Will this cause an issue with GRUB? Will a Windows 7 loader be added to the list or will a Windows 7 loader replace the Windows Vista loader? Will there have to be a setting change within Debian? Within Windows?
Two days ago i turned on my pc and suddenly there was a message:"Minimal Bash-like line editing is supported.For the first word,TAB lists possible command completions.Anywhere else TAB lists the possible completions of a device/filename.ESC any time exists...
When i googled this message it came out that this has got to do with linux (i have never used linux and i formated my disc once or twice since i bought it so i found it very strange that this problem is related to linux).Anyway,i found out that grub is the problem and that it isnt a big deal to solve it.I downloaded Ubuntu,booted it from the cd and followed the instructions...I typed in grub (in the terminal) and it told me to download it so i typed in "get-apt grub install" or something like that and it all went well,i was now in the grub directory.Then i typed " find /boot/grub/stage1" and it told me that the file was not found.
I have tried everything,i have downloaded the super rescue cd the fix the problem but i have still the same problem.
I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I have recently purchased a new laptop, which came with Windows 7 pre-installed. I immediately installed Ubuntu alongside it with a dual boot. At first it worked fine, but when I restarted after the first time I used Windows, I ended up with an 'Operating system not found' error. I was able to reinstall the Grub bootloader using an Ubuntu Live CD, which appeared to fix the problem, but the next time I loaded Windows 7 and rebooted, the problem reappeared I think the problem is that Windows 7, for whatever reason, is somehow removing or disabling Grub.
I had 9.10 installed and I did an upgrade to 10.04. However I cannot see anymore my Windows Vista partition with grub.. I have a Toshiba laptop Satellite p305.This is my boot script output:

how to be able to add windows 7 to my grub menu or to even be able to boot to windows 7. I am currently unable to do it and my system just automatically goes straight to ubuntu. I've tried holding down SHIFT during startup and all that appears in my list is ubuntu entries and a memtest entry. My windows 7 files are still intact because I can see the drive through ubuntu and see all my files. I am trying to have Windows 7 on one hard disk that is 640GB and ubuntu on a second hard disk that is 160GB
I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.
A few days ago I went to perform the Service Pack 1 Upgrade for Win 7. This crashed out with an error. On researching the problem I found a solution to fix the problem by marking the Windows partition as active. I did this (via Computer Mgmt -> Disk Mgmt). This allowed the SP1 upgrade to work, however on reboot I got an error BOOTMGR missing. This I rather rashly resolved by using the Windows 7 install DVD in Recovery mode to reinstall the Windows Boot manager via bootrec /Fixboot I thought I would then be able to use the Opensuse 11.2 install disk to fix grub.
I use the Opensuse install disk and select Repair system -> Expert Mode -> Install New Boot Loader then select Other -> Reread Configuration from Disk. This adds Win 7 back into the grub menu. I then select OK and get the message "the bootloader was installed successfully". The problem then comes when I click my way through OK and Next to finish the install. At the end of the process I get the message "An error occurred during the installation" and I'm no further forward.
FYI the PC has a single SATA disk installed partitioned as follows:
dev/sda1 100Mb Win System Parkition dev/sda2 Windows NTFS dev/sda3 Windows FAT
I have just installed Ubuntu, now when logging into my laptop i am able to sucsessfully load ubuntu but i am unable to load the original OS (windows 7).
The grub 1.9 bootloader gives me the option
When selecting this option it goes to a black screen with a - in the top left of the screen then the grub screen re-appears
I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).
I installed grub on the Fedora disk so as to not touch the windows disk at all.
Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)
My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?
I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:
mount: wrong fs type, bad option, bad superblock on /dev/sda5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try
The problem is I've set up a dual boot with Xp and Ubuntu 10.04. Ubuntu was working fine till 2 days back but now when I select Ubuntu from the grub screen i get a whole lot of numbers next which it'll say Usb drive or sd card reader etc.. these go by quickly and then the comp stops running. If i press enter on the keyboard I get Initramfs and then i can type but nothing happens even if I type reboot. if I press cntrl+alt+F2 then i get a blank screen with flashing cursor. Same with recovery mode. Windows boots fine. The grub2 screen comes fine. The last thing i did before this happened is reconfigure the grub2 screen, but it seems to be fine (i had added a background img and reordered the boot options) I did not edit grub.cfg. I would prefer not to reinstall it as iv done it a half a dozen times already in the last few weeks..
through a series of mistakes i have managed to take a working system and make it unable to boot. my two objectives right now are to back up my data, and to make my system bootable. here's how i got here. i used the Upgrade Manager to upgrade to 10.04 thinking it would solve a problem i was having with my previous installation. when that had completed i found I was unable to boot into 10.04. The system would hang after echoing the message "checking battery state." I attempted to rebuild my grub file, thinking this would solve the 'battery state' problem. this was a mistake. I ended up deleting it, and now there's no menu.lst file in its place.
currently when i boot up normally (i.e., with no Live CD) I automatically go into the rescue mode. so far i haven't managed to enter a command that rescue mode recognizes. alternatively, i can boot from the installation CD for Ubuntu 10.04. per this page: [URL] I take these steps:
1. boot from the installation CD. 2. go into terminal 3. type these commands:
I had Windows XP installed on my PC then bought a new HDD, installed Windows 7 & Ubuntu 10.10 in dual boot, later I added the Windows XP HDD as an external USB then typed "update-grub".
At boot up the drive appears at the bottom of the GRUB menu but when I select Windows XP it gets as far as the XP splash screen, after a few seconds there is a flash of blue screen with some writing on it then the PC re-boots. Here is grub.cfg:
Code: # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub
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:

Having a major issue with my laptop. I am unable to boot into my Vista installation.I am currently posting this through my Fedora 11 installation which I had already. If anyone is interested, the BSOD error is:
As far as I know, a '7B' BSOD is usually a hard disk error but I am 100% sure the HDD is fine as I can read and write from both Fedora and Knoppix without issue. Steps taken so far: Obviously, I have tried the usual steps of trying to start windows in safe mode, last good config, and all of the F8 options. When they failed, I used fedora to check for some solutions online (Mostly useless answers from MS) and I found one successful case when a person flashed his BIOS back to an earlier time. Unfortunately, I cant get the BIOS update I got from the Dell website to boot from a USB drive (Says invalid boot disc - the BIOS on it is in the .exe format which I can't use in linux) and I do not have a floppy drive on the laptop.
So, I put in my Dell drivers and utilities CD hoping that it would give me some option to update (Or roll back) the BIOS but there was no such option. However, it did give me a load of diagnostic options including repair options by symptom so went with the "Unable to boot from BIOS". Unfortunately, that didnt help me at all. So, I got my Vista installation disc (OEM supplied) and managed to get to the repair menu (Which I had among my F8 options anyway) but this also has the option to reinstall. Unfortunately, it states that "Upgrade is unavailable" and that a clean install is the only thing I can select (At the expense of my files and settings).
As for the repair options, the automatic recovery doesn't seem to find any errors, asks to reset and see if all is well (It isn't). For some reason, system restore doesn't detect any restore points. There are no windows memory errors detected and I have no backups. So, i'm left with a command prompt that, by default, is asking for a file in this folder: X:/WINDOWS/System32/ I have no idea where it is getting the X: drive from - I have C and D drives for windows only. As per another online guide, I tried:
I have Win7 and ubuntu installed on the same PC. Win7 was installed first, after I installed GRUB from Ubuntu, Win7 is not listed as a second option to boot. FYI, On the same PC I had Win7 and Debian (before changing from Debian to Ubuntu) and GRUB from Debian was showing Win7 as second option for boot. Ubuntu was installed on the same partitions as Debian. (For Win7 I have 2 partitions one 100M-system reserved and one 30G; both on NTFS). I have: Linux ubuntu 2.6.28-18-generic #60-Ubuntu SMP Fri Mar 12 04:40:52 UTC 2010 i686 GNU/Linux How to set /boot/grub/menu.ls file to add Win7! (I will do also a fresh install for Ubuntu 64Bit)
