Rescuing Windows Vista as well as Fedora through bootable USB
My system was a dual-boot with Windows Vista and Fedora 9. During the installation of some updates of Windows vista I powered off the system and since then my Windows Vista gives blue death screen error. I think it as some MBR corruption issue for which I have searched these corrective steps:

My Problem: At present Fedora boots normally. But when I will fix MBR, what will happen to fedora ? If it removes the grub, I will not be able to boot in fedora. Please suggest something. I think there must be a way to install grub through USB, but I don't know the 'howtos' of that. Thanks |
You would boot a LiveCD after restoring the windows MBR and then do
Code:
grub-install /dev/sda |
Ok. Thanks ctkroeker.
So now I have created a Live USB with Fedora-9-i686-Live.iso using liveusb-creator. When I boot with this LiveUSB, I only see four options: Quote:

Code:
fdisk -l |
Okay I got it. You mean when I am taken to the desktop of fedora through LiveUSB, I can access the terminal and put this command. Right, thanks. Now two questions:
First, you told me the command 'fdisk -l' to view the drives. Is this some kind of a hint ? I mean why I will need to view my drives ? Will not 'grub-install /dev/sda' alone enough? Second, and very important. I am doing my project in fedora. If something goes wrong, all my project data will be doomed. Consequently, I may be killed by my supervisor !! So do you think everything will be ok ? In fact I want to load myself with the every the information that I may need for this rescue operation. In fact, I am not only a newbie but also some kind of a dumb as a bonus. So please bear with me. Thanks |
You need fdisk -l to identify your drives
if say you have windows on /dev/sda and another drive thats /dev/sdb and you do grub-install /dev/sda then its gonna install grub to your windowds drive which would be bad you could use a persistent fedora usb install to back up data to and could also just compress your datd and place it on usb,etc before doing anything you should always back-up stuff |
Ok. Thanks linus72. I am getting things clearer now but not cristal clear.
Right now I am in fedora 9. So I tested the command fdisk and much worried by getting this: Quote:

You gotta be root/admin to run a command like fdisk
any command that can/will potentially destroy your hdd must be run as root sudo fdisk -l |
Humm..thanks linus72.
Let's do it: Code:
[mq15@localhost ~]$ sudo fdisk -l Code:
Disk /dev/sda: 120.0 GB, 120034123776 bytes Quote:

I guess, grub.conf will be also needed for this decision:
Code:
[mq15@localhost ~]$ su -c "cat /boot/grub/grub.conf" Quote:

hi
your menu is grub-legacy so boot a live cd open a terminal and Code:
su Code:
su but put a # in front of hiddenmenu and save the file then reboot and cross your legs |
You can use either MS's or Grubs loader for both.

Thanks jefro. Yours idea is novice to me. Can you elaborate please??

O.K.
Thanks everyone. Windows Vista was not being repaired. I installed Windows 7. After that I followed instructions in post # 11 by aus9 to re-install the grub. One common error that I would like to share: Code:
root<space>(hd0,2) Code:
Error 27 Unrecognized command |
