fixing grub

[teddy92]

hi!
recently i installed windows 7 :evil: on my system and obviously ubuntu didn t boot again :)
i tryed to restore grub in all ways i found but i failed..at last i installed a new copy of ubuntu on the swap partiotion and it worked, but so i haven t got a swap partition anymore :(
is it possible to reinstall grub from scratch on the first partition?
this is my fdisk -l:

Hi. This is linux, you can do anything. :)
But I'm not sure what you mean and what you are trying to achieve. sda4 is listed as a swap partition.

Please boot from the Ubuntu Live cd/usb and select "try ubuntu" then when the desktop is loaded make sure you have an internet connection and go to the site below and download the boot script to your DESKTOP and then open up a terminal (Applications > Accessories > terminal) and run


sudo bash ~/Desktop/boot_info_script*.sh

This will produce a results.txt file on your desktop. Please copy the contents of that file and paste them in your next post between CODE tags. For CODE tags click on New Reply (not quick reply)and then click on the # symbol in the toolbar.
This will give a full overview of your current system.
Thanks.
