I had been dual booting Vista and Ubuntu for a long time and now i had decided to totally ditch Vista.
I had modified GRUB to remove Vista startup entry but i still have one important question: How do I reclaim those partition from vista? Here is my current drive map:
I wish to reclaim the vista partition (/dev/sda1) without require to reinstall ubuntu. my mount point of /dev/sda3 to / and /dev/sda4 to /home
/dev/sda1 * 1 9773 78499572 7 HPFS/NTFS
/dev/sda2 9774 9967 1558305 82 Linux swap / Solaris
/dev/sda3 9968 10575 4883760 83 Linux
/dev/sda4 10576 24321 110414745 83 Linux
