Debian Installation :: Super Grub2 Will Work After Vista Reinstall
Mar 16, 2011
I have a dual boot system. I need dual boot as my dictation software is only available for Windows. In the future I am going to try a virtual machine, but dictation and audio did not work properly the last time I tried in VM. But unfortunately for now I have a dual boot machine with Vista and Debian 6. Unfortunately, I am going to have to reinstall Vista. Or to be more accurate I'm going to install the 64-bit version instead of the 32 bit that came with the computer. I have the 64-bit version that I no longer use from one of my other computers.
Anyway, I have to install Windows which will overwrite my grub2. Is there anyway I can make a backup or reinstall grub2 after I install Windows. I really don't want to reinstall Debian 6 squeeze. Can they make some sort of a backup of gurb2 before I do this. I checked out the Internet and I found something called Super Grub2. It apparently will allow me to boot back into Debain 6 so that I can install grub2 again. Assuming, Super Grub2 even works then how do I reinstall grub2 once a boot into Debian 6? Has anybody tried Super grub2, does it work? It's kind of hard to test it, with a working version of grub2.

How can I restore or reinstall GRUB2 from squeeze installation? I tried various suggestions from various online articles (most of them for ubuntu), but I couldn't find a solution. Is there any solution, specifically for Debian? GRUB reinstallation from install cd, didn't worked as well. Since I couldn't boot at all, I restored GRUB1 and I'm posting from Lenny, but I can't access Squeeze this way (probably because I have squeeze's partition, ext4 formatted).

I have Ubuntu 10.04 on my laptop. If I wanted to reinstall Windows Vista over the top of Ubuntu 10.04, do I just install Vista normally, as if I was reformatting the hard drive?

My friend recently re-installed WinXP on his laptop, but I'm having trouble getting Grub2 working. I followed a guide online, but when I booted it back up again, I got a Grub prompt instead of a boot menu.

I was dual booting Ubuntu and Windows, had to reinstall Windows, it wiped out grub, need to reinstall it now. Was following this: [URL]
Trying to reinstall grub with:
Code:
sudo grub-install --root-directory=/media/d566e91e-941f-4433-8dea-05d3bffb5669 /dev/sda6
Gives me the following error:
Code:
/usr/sbin/grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea..
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are unreliable and their use is discouraged..
/usr/sbin/grub-setup: error: if you really want blocklists, use --force.
*edit more info* Ubuntu is installed on /dev/sda6 on a 50GB partition.
Code:
Device Boot Start End Blocks Id System
/dev/sda1 26 56830 456280064 7 HPFS/NTFS
/dev/sda2 * 56830 56843 102400 7 HPFS/NTFS
/dev/sda3 56843 70981 113561600 7 HPFS/NTFS
/dev/sda4 70981 77826 54979585 5 Extended
/dev/sda5 77096 77826 5859328 82 Linux swap / Solaris
/dev/sda6 70981 77096 49120256 83 Linux
Partition table entries are not in disk order So, I didn't want to do anything and screw things up. I want to boot with grub and not MBR. What should I do?

I recently installed Ubuntu 9.10 onto my second hard drive, and now I can't boot into Vista (installed on hard drive #1). Grub2 just doesn't seem to be recognizing that there is a Windows Vista installation on the first hard drive.
I followed this guide (with Fabien's changes) because it seemed like they were having the exact same problem. But after rebooting, Vista is still not showing in the GRUB menu. In fact, the GRUB menu doesn't even show up unless I press Shift because it thinks that Ubuntu is the only OS installed on my computer.
My results with boot_info_script:
Code:
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=e94a058d-1d19-4a98-924b-1a5fce405bdd)/boot/grub.
=> Windows is installed in the MBR of /dev/sdb sda1:
[Code]....
When I was installing Ubuntu to HD2 (the 500gb one), I got a peculiar message saying that Windows was installed on it. There wasn't anything on HD2 though, because Windows Vista was most definitely installed on HD1.
However, if I chose to overwrite HD1 with Ubuntu, the message wouldn't come up. It seemed like the installer was confused as to which hard drive actually held my Windows Vista install.

I tend to update stuff slower than most - I'm still using Hardy and I probably won't upgrade to Lucid until June-ish. I wanted to test drive GRUB2 so I upgraded following instructions here:When I chainloaded GRUB2, I got a menu that only contained Ubuntu; my Windows Vista bootloader entry had disappeared. I couldn't find a sample "40_custom" entry to modify when I tried to create an entry for Vista myself. Had no problem booting into Ubuntu and I could still boot Vista from the old menu. Spent about 20 minutes on it, then I gave up and reinstalled legacy GRUB.

After running wireless for years my system crashed, I've had to re install lenny and now what ever I try I can't get the wireless to work. I'm running Lenny, kernel 2.6.26-2-686 but when I start up it doesn't seem to be able to start the wireless, whatever I do from gnome wireless tools,

i am running lenny. and at some point my grub started exibiting a strange problem. Grub will not display all the kernels that it finds, it only displays 2 of them out of the 5 grub was finding.the system is working and boots just fine.
I attempted to install GRUB2 which went ok. since my system booted ok i removed GRUB that operation was sucessful and it deleted all the grub files that were not needed.but my system is still booting into grub with the same 2 kernels.Could someone tell me what i can do to either get grub or grub2 to work?

I want to reinstall windows to its partition on my computer, but I want to be able to restore grub2 afterwards. I use a lot of custom scripts in the /etc/grub.d/ directory on my ubuntu partition, so how can I reinstall grub to the MBR using those specific scripts? Just running "sudo install-grub" or "sudo update-grub" doesn't work for me (I don't know the exact problems, but I can't reproduce it right now). If there's a way to install just the defaults (without overriding my custom scripts!) maybe I can just do that, but I'd really like to put the live cd, run a few commands, and install those custom scripts to the mbr and be on my way.

I have been following (200 instructions on how to do a clean install without losing settings.I used the command<sudo dpkg --get-selections > /home/user/package.selections>to create a list of installed applications.My problem is that the instructions to reinstall those packages does not work. The code given is<sudo dpkg --set-selections /home/package. selections && apt-get dselect-upgrade>.However when I try and run this code I am told that "--set-selections takes no arguments".So I need some revised code to reset the list of applications for re-installation

I first installed asterisk using sudo apt-get install asterisk on ubuntu 10.04. After doing this the SIP packages did not install for some odd reason.I uninstalled asterisk using sudo apt-get remove asterisk then reinstalled and now none of the asterisk config files are gone. deleted all files and directories I could find relating to asterisk, rebooted the machine, did a kernal upgrade, and a package update and reinstalled asterisk using sudo apt-get install asterisk, and all the config files are still missing. What am I missing here!

Had a working WinXp/Karmic dual boot system. Tried to upgrade Karmic to Lucid and my daughter rebooted the system during the upgrade. I decided to do a fresh install of ubuntu, leaving Windows in place and it succeeded until the end when it said it could install the bootloader, so I proceeded without. I meant to say "it said it couldn't install the bootloader, so I proceeded without.
On booting, Grub drops to the command line.
I get grub>, not grub-rescue>
I did ls in grub and it showed the partitions I expected
/sda5 is /boot
/sda6 is /swap
/sda7 is /
/sda8 is /home
I tried to follow the grub2 command line manual by entering
Code:
set root=(hd0,7) (success)
linux /boot/vmlinuz-2.6.32-24-generic root=/dev/sda7 ro (failed - couldn't find file)
so I'm now a bit stuck.
Here are my bootinfo_script results (by the way, sdb is just an e-SATA hard disc with nothing installed on it, I don't know why bootinfo thinks Windows is there. Windows is on /sda2 with some sort of backup/recovery partition on /sda1)
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #7 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb .....

Recently, I reinstalled(recovered) Vista in my dual boot (with FC12) HP Laptop. After Vista recovery, I did not find any option to boot FC12. I tried to install grub in rescue mode from my Fedora DVD with command "$grub-install /dev/sda", but could not succeed. There was a message like 'grub-install not found in /sbin'.

I recently (for about the third time) HAD to re-install Windows 7. It just wouldn't boot and unfortunately I have some proprietary software that I need to use. Anyway, this is the first time I've had to do so since installing Lucid (64bit, fresh install). My problem now is, when I re-installed Grub2 (using the same methods that have previously worked flawlessly) to recover it after re-installing windows, only windows shows up in the grub menu, showing options to boot to Windows on sda1 and another to boot to Windows on sda2.
I grabed a "boot info script" from Rubi1200 and this is what I got..
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #1 for /grub .....

This is closely related to a recent thread of mine that I unfortunately marked as solved prematurely. I'll try to keep it brief this time. After editing partitions I was left with a boot problem, namely "error: no such partition" and I am dropped at the 'grub rescue>' prompt. I can issue the appropriate grub commands and successfully boot the current kernel. Once booted, I executed 'sudo update-grub' and then /boot/grub/grub.cfg was rewritten with all drive and partition references correct. Likewise, /etc/fstab is also correct.
The problem comes when I attempt to reboot. I still get the 'no such partition' message and the 'set' command reveals that grub is still trying to reference the old partition. I've never encountered this problem before under similar circumstances. I'm guessing that this info must be stored in the disk's MBR as well as in grub.cfg because that file looks completely correct. Am I going to have to reinstall grub now?

I assume that I have not understand grub2 correct and need help.In the past I have used grub legency in the following configuration.SDA6 = 2 GB partition ONLY for grub as bootmanager.I have sda1-sda3 and sda7 to sda9 as system partitions.As backup I used TAR to an nas system and this way I could restore any partition from the tar file to any partition on my harddisk.The only part which I did manual was edit FSTAB on the recovered partition and modified the grub menu.cfg.This way my bootmanager was independent from any operating system and partition (except sda6).When I replace the harddisk, a recovery of grub legency was easy and after I copied the backup files back to sda6, I could continue to to restore the tar files and my system was up and running again.
Now with grub2 each linux installation thinks it is the master of my harddisk and takes over control from my sda6. Yes it discovers other linux versions etc but I loose control over my bootmanager.How can I use grub2 with an independent bootpartition (sda6) and how can I configure this bootpartition (sda6) from each installed linux partition? With other words no FIXED linux partition is responsible for my bootmanager. for someone asked why I need more versions of linux � the free vmware server 2 does not work on newer versions of linux. The latest vmplayer can not work with newer version of firefox. This is ONLY an example why I have more as one version of linux.

I have drive C/ with Vista, D with as of now, nothing and a third logical partition with Ubuntu on.
I want to do a clean install of Vista on top of my current system, just on C.
Will this re-install the Windows MBR and prevent Grub2 from booting? If so, how to I re-set grub2 as the MBR?

I'm still not all confident using sudo, so if you could explain what I need to do in simple steps including the commands I would be ever so grateful. I need my Windows back 'cause while I'm perfectly happy on ubuntu at home, my boss at work thinks Linux is an exotic metalworking tool (or something like that).

how to use the <Super>ButtonX (<Super>Button1 for example for the enabled Compiz Screenshot plugin)? I also notice there is configurable buttons 1 throught 20 under the various options. At first I thought the ButtonX was a mouse button. Maybe it is with some anticipation of there being eventually being a possible 20 buttons on the mouse. I know the Super key is the Key with the Windows logo on it. But I don't know what to do to get the needed Super Key / Button combination. After having enabled Compiz's Screenshot plugin by its default, I don't get an image after hitting any of the Super key and mouse button combinations. I'm running Ubuntu 11.04.

I installed debian with Root, swap, /home, /usr, /tmp, /var on separate partitions. Then my root partition hdd is physically damaged, so I have to reinstall. But how can I keep/remount those other partitions which has lots of important data(mainly webserver data and mysql database) back? Another thing to note is that I not only replaced the root HDD but also the whole desktop pc which is smaller pc so instead of internally connecting the other partitions(another undamaged Harddrive), I have to use USB adapter externally which seems to work just fine. But how do I "re-link" my partitions?

I'm running Ubuntu 10.04 minimal with Openbox; far from a standard install but nearly everything works the way it should.
The problem appears quite simple:
Firefox does not recognise installed plugins (i.e, Flash) when running as the standard user; if I run the command 'sudo firefox' however, Firefox loads in plugins just as it should.
I've checked about:plugins in both instances and this has confirmed what is stated above. The list is populated when running as the super user, and empty when running as standard.
