After windows is reinstalled, modify the grub boot Fedora 7

A few days ago, due to some misoperations, Windows XP broke down and I didn't want to reinstall it immediately. After the startup, I found that my Fedora 7 was not found in the boot menu.

So I went online to findArticleLook, I tried to reinstall grub with the rescue CD of Fedora 7, but I failed to try it. The most common method is as follows:

# Grub
Grub> root (hd0, 5)
Grub> setup (hd0)
Grub> quit
#

An error was reported during setup, indicating that the installation could not be completed. The grub-install command could not be installed. Finally, I decided to try wingrub.

I got a wingrub in sourceforge.net and checked that the date was before 05 years .. the result is that there is no MBR option during installation on XP, and grub/menu cannot be entered after restart. interface under list ..

Finally installed with climbing version of grub (http://nufans.net/software/tools/grub_climbing_v7.exe), restart, see grub installed successfully !!

Next, use explore2fs to read/boot/GRUB/menu. lst under fedora.

Copy the content of Fedora started in menu. lst to the file corresponding to C:/boot/GRUB/menu. lst.

In menu. lst under my own fedora, the text that starts fedora is

Title fedora (2.6.22.1-27. fc7)
Root (hd0, 6)
Kernel/boot/vmlinuz-2.6.22.1-27.fc7 Ro root = label =/1 rhgb quiet
Initrd/boot/initrd-2.6.22.1-27.fc7.img

In the menu. LST file copied to wingrub, the number of the partition where fedora is located must be reduced by 1 and changed to the following one. The other values can be unchanged:

Title fedora (2.6.22.1-27. fc7)
Root (hd0, 5)
Kernel/boot/vmlinuz-2.6.22.1-27.fc7 Ro root = label =/1 rhgb quiet
Initrd/boot/initrd-2.6.22.1-27.fc7.img

If you have other systems that copy the same copy, you can subtract 1 from the Partition Number.

FreeBSD has not been restored. I have read the article saying that this is relatively simple. Wait for a rest and try again ..
This grub is too difficult to install. I still don't understand it, so I have to try it out first.
