Guest ManyBeers Posted September 8, 2008 Posted September 8, 2008 If your XP SP3 computer has no WindowsXP cds but only factory Recovery CDs with no Recovery Console how would one go about rewriting the MBR if it was somehow damaged other than reinstalling Windows or an image of the Windows drive?Aren't there floppy discs that can do this? My laptop has a floppy drive.

You can restore the MBR like so: - Download a Win98 boot diskette from http://www.bootdisk.com. - Boot the machine with this diskette. - Type this command: fdisk /mbr It works for WinXP machines and for NTFS partitions (because it replaces the MBR and does not access the partitions).

I think you should alternatively create a Recovery Console even if this problem is fixed. http://aumha.net/viewtopic.php?f=62&t=31844 Subject: Add "Recovery Console" to your Boot Menu -- Now!

Thanks Steve but I have in fact already done so uses that very thread as a guide. The deal is I am thinking of dual-booting with linux Ubuntu 8.04 and ther are basically 2 ways of going about it. When Ubuntu is installed it asks where you want to install GRUB it's bootloader and if you install it in the MBR it will overwrite Windows bootloader And make Ubuntu the default op system to boot with Windows as an option. However according to a guy on Ubuntu's support forum I would lose my Recovery Console entry. I don't like that part. A secondary method retains all of my boot options since it uses Windows own bootloader and adds Ubuntu to boot.ini. This method is a little riskier I think because at one point in the install there is a point where neither OpSys can be booted but is relativelt easy to fix-at least according to this guide:http://www.linuxdevcenter.com/pub/a/linux/2006/05/08/dual-boot-laptop.html?page=1 So I think letting Grub be my bootloader is probably eaier for me but my concern is if I ever dump Ubuntu I want to make sure I can get my Windows bootloader back. I have an image of my Windows C: partiton made with Image For Windows(Terabyte) and looking at it's imaging parameters it does appear that the image includes the MBR so I am probably covered there. What method would you use if you were me?

I have never had a problem with it, where it didn't boot to an OS, it proceeds automatically. The first method is the default because a dual boot is not the default. Read how to get to a 'use the first sector' boot screen option before you install Ubuntu. I read your web link which is about Ubuntu 5.10, I'm not sure his problem still exists. Check on the Ubuntu forum. Don't forget to get a backup/restore MBR utility and backup the MBR, so that you never lose Windows. One can edit the boot.ini to change the default OS. I think in Linux its counterpart might be grub.conf which can also change the default boot OS plus the timeout period. > So I think letting Grub be my bootloader is probably eaier for me but my > concern is if I ever dump Ubuntu I want to make sure I can get my Windows > bootloader back.

What method > would you use if you were me? Not installing Ubuntu in the MBR. Use the XP boot.ini. I think that is easier if you don't have to go through those extra setting partition active steps. I know that you don't have to do that using Redhat. Ask again in the Ubuntu forum. I think you will be surprised about how much you have to learn just to install a third party utility like Flash player, using Ubuntu. Until you become accomplished with Linux, don't risk what you know, XP.

What method > would you use if you were me? In my previous post I said the url you provided was out of date. https://help.ubuntu.com/community/WindowsDualBoot "If you have a problem with changing the MBR code, you might prefer to just install the code for pointing to GRUB to the first sector of your Ubuntu partition instead. If you do that during the Ubuntu installation process, then Ubuntu won't boot until you configure some other boot manager to point to Ubuntu's boot sector. Windows Vista no longer utilizes boot.ini,..." SH: Dual booting with XP is easier than with Vista. Since the boot code is written to the first sector of the Ubuntu Partition, it shouldn't mess with the MBR, which means it should just boot to Windows. One should still have their backed up original MBR handy on a floppy disk or USB stick ready to restore the original MBR just in case. So in XP, which does still use boot.ini, just safely add the line C:\ubuntu.bin="Ubuntu" to the boot.ini. [boot loader] timeout=5 default=multi(0)disk(0)rdisk(0)partition(1)\WINNT [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows XP Professional" /fastdetect C:\ubuntu.bin="Ubuntu" SH: You can add this before installing Ubuntu. And maybe the Ubuntu boot file information is menu.lst rather than grub.conf. You can add ubuntu to the windows boot loader: Boot from the LiveD. Step 1) Install Ubuntu. On the last screen click on the "advanced" button and replace (hd0) by /dev/sda3. (Here you need to replace sda3 by whatever partition Ubuntu is on) Don't reboot immediately. Instead stay on the LiveCD. Step 2) Mount your Windows partition: sudo mount -t ntfs-3g /dev/sda2 /windows (Here replace sda2 by whatever partition Windows is on) Step 3) Copy the first sector of the Ubuntu partition to a file on the Windows partition: sudo dd if=/dev/sda3 of=/windows/ubuntu.bin bs=512 count=1 (Be very careful when using "dd". Info on dd (http://linuxreviews.org/man/dd/)) [alternative method] Step 4) Add ubuntu to the windows boot loader: Open "boot.ini" from the Windows partition via sudo gedit /windows/boot.ini Add this line to the end of the file: c:\ubuntu.bin="Ubuntu" Save the file. Reboot and you get should get a menu with a Windows and Ubuntu choice." SH: You should have a file named ubuntu.bin in your root directory, C:\ , where the hidden file boot.ini resides. Just the reference to the file ubuntu.bin is contained within boot.ini, C:\ubuntu.bin="Ubuntu" One can often tell what is the right name for the partition by looking at the size of the partition related to that name.

Somehow! All that mounting stuff , command line stuff, is new and scary to me as I am pretty much a "mouse only" type guy. But I will get it done.

There is a learning curve for Linux that starts when you leave the mouse clicks, and ability to ignore permissions, behind. You are going to have to be innately geeky to suffer through the frustrations. You will see what I mean when it comes to installing a free flash player under Windows and then under Ubuntu. I mean why dual boot if you are just going to stay at the same point and click level using both Os's? Gimp and OpenOffice have been ported to Windows. IMO, there is more enthusiasm in the (younger) Linux community. Good Luck!
