Windows Vista & Fedora13 dual boot, replace vista with Win 7 without affecting Fedora
 
Hello Everyone,

I had Windows Vista Business in my compaq presario CQ40-145 TU laptop, over which I insatlled Fedora 13, making the system dual boot. The Windows is set to be the default OS.

Now I want to replace Vista with Windows 7 professional without affecting Fedora. As far as I understand, during boot up, the system enters Fedora's booting process and then gets redirected to Windows, and it is not directly windows even if the default OS is windows.

The reason behind not disturbing fedora is the updates, extra softwares and packages installed and the pain and time it took me to make my speakers, wlan and flash player work in it. I even don't remember the exact process of what I did. I don't have now so much time to search for it again.

So I will take up only that way in which Fedora is not affected at all.
And the second problem is my DVD drive is not working at all. So I'll like using USB stick for the same.Please guide me.

Thank you in advance.
Avantika

There are two main problems in this regard,

1) MBR (Master Boot Record)
2) Partition of Linux



For making save to your fedora you have to take care of both above things

for installation you have to know the Linux Partition and take care of it, dont delete or install windows on this partition.
2nd is MBR which may be changed during windows installation this issue can be solved by reinstalling boot grub with live CD of Linux.

May be other persons on this forum can give you other important things and better solution.
there may be other issue you can face, which is data on the other partitions to be saved.

Hey, when you install windows 7, it will rewrite the mbr and you'll no longer have an option to boot fedora. Though this can be easily solved by:
1> Reinstalling grub from the fedora live cd .
or
2> Using a windows app called easybcd it will allow you to add fedora to the boot menu.

Just make sure you dont destroy the linux partition.

And if you can spare the time, wait for some senior to guide you better.

Thank you Sohail and rohanvr.

My dvd drive is not working. So I have to rely on usb for everything. I have found a microsoft's utility that allows me to make pen drive bootable from iso. There is something called "unetbooting" that allows making pen drive bootable for linux. Will this usb live "cd" will reinstall grub same as actual live cd? And also which option and how is to be selected to repair the grub?

Secondly, I have seen my friend using easybcd application to make xp boot when she installed xp over 7. But will the same application work to repair linux system as well? Are you sure? I don't doubt anyone, I am asking just because I want to be sure.

Also if someone has any idea then I wanted to know that my laptop came preinstalled with Win Vista, for which I have got a set of recovery discs. But I know that can not be used to install that OS in parellel to other. That can only be used to restore my laptop to factory state. Is there any way to get Vista ISO out of it? It is Windows Vista Business.

I'm not familiar with that utility.

unetbootin is designed to install various Linux distributions from usb to a hard drive. You should be able to also install Grub from it to your hard drive if the Grub files are on the usb.

Easybcd is designed to edit the bootloader of vista and windows 7. vista and windows 7 have totally different boot files from xp. I've read that it can work to boot xp but have no experience with it.

EasyBCD will work to boot a Linux distribution (usually) but it won't repair any Linux system. If you have all the right Linux boot files on your Linux root partition, you should be able to set EasyBCD to boot your Fedora.

In answer to your last question, I don't know but I seriously doubt it.

also with fedora if you EVER want to use the "preupgrade" option your boot partition MUST and i DO MEAN MUST be bigger that 700 meg ( 1 gig min is better)
the default install is only 100 meg

i do not know just how bcd will react to a 1 gig MBR , or how win 7 will react

but seeing as fedora 14 will be out in about 3 weeks

wait 1 month back up all your data reformat the drive
install win 7
then install fedora 14

@skm3nt 10-10-2010 04:45 AM

Thank you everyone. I want to know if I create a bootable USB from live CD image I have, how can do the grub installation(and not the complete OS) from that?

John VV 10-10-2010 01:35 PM

use the install/live cd in rescue mode and reinstall grub
-- for grub on the mbr ( first hdd )
Code:

chroot /mnt/sysimage
grub-install  /dev/sda


@skm3nt 10-11-2010 05:56 AM

Thank you so much! That piece of code will be very handy to me.
Well, but should I assume that my grub is on the mbr (first hdd). How do I know that? I installed with 3 paritions, boot swap and root. It automatically detected the presence of other OS and added to list, asking for the 1st OS to boot in.
