[ SOLVED ] Still not understanding how to reinstall Grub ?

whitetimer · 2011-01-02 11:45:07

Hi All

I currently have a dual boot windows 7 & Arch system and i have to wipe the Windows partition and reinstall. But i am still confused as to how to reinstall Grub once i have reinstalled windows 7. The wiki post is not longer available and have not found anything that explains what i need to do ... So can anyone point me in the right direction or explain what i need to do ?

Many Thanks

I think the easiest solution is to chroot into your arch install after you finish with the windows install. Then it should be fairly easy to reinstall grub to the mbr.

For chroot check out https://wiki.archlinux.org/index.php/Chroot
And for grub this should help you on the way: https://wiki.archlinux.org/index.php/Grub

Hope this helps.

To be clear, you should use the live CD to boot the system if you are unable to boot into Arch after Windows rapes your MBR.

Or you can use sysrescd: http://www.sysresccd.org/Sysresccd-Part … maged-Grub

Feel free to use my setup_chroot script after you boot from a live CD to do it:

Thanks for the advice ... The LiveCD, do you mean the normal 'Install from Net iso' as i cant seem to see the LiveCD for download ?

# FLAWLESS GRUB REINSTALL GUIDE BY DARKBEANIES ASSUMING YOU USE EXT3 FILESYSTEM

# Boot arch install cd and login as root, and type the following commands in order, replacing X and Y values with the number of the partition/disk(MAKE SURE YOU GET THIS RIGHT, ASK IF YOU DON'T KNOW)

cd /
mount -t ext3   /dev/sdaX /mnt
mount -t proc   proc      /mnt/proc
mount -t sysfs  sys       /mnt/sys
mount -o bind   /dev      /mnt/dev
chroot /mnt /bin/bash

#------------------------------------------------------------------------
#IMPORTANT-ONLY IF YOU HAVE SEPARATE BOOT PARTITION

mount -t ext3   /dev/sdaX  /boot

#------------------------------------------

#Then try:

grub-install /dev/sdaX

# -WHEN- this fails type this:

grub
root (hdY,X)
setup (hdY)

#Then reboot:

cd /
umount -a
exit
cd /
umount -a
reboot

#That's it!

Why oh why was this page removed from the wiki I do not know...

Live CDs of various flavours available HERE: (Don't you have the CD or whatever you used to install to begin with?)

@ darkbeanies

Yes i do, i just wanted to clarify that the installation cd was infact the LiveCD

Many Thanks

@whitetimer
Yes, both the net and core installation CDs are live CDs.

@darkbeanies
Please use code tags for code.
