Remove Windows 7 and restore GRUB?
 

K so before I had Vista and Ubuntu with GRUB, now I made another little partition and tried out Windows 7 RC, so far it rather sucks as the video glitches out a lot and most of my games won't work. Now I'm just trying to figure out what order I need to do what things in to remove 7 and restore GRUB as my bootloader instead of the one 7 put on here.

delete windows 7 partition
msconfig > boot > set vista as default. - delete other necessary OS bootup.

ok sweet, main thing I wanted to be sure of was that nuking 7 first would mess up my boot

delete the 7 partition(s). once you have only the vista partition and the ubuntu partition, you will need to config either grub, or config the bcd for the vista ntldr.

if you want to get grub back on there, you will need to put in your ubuntu cd and boot to it (live cd boot). then in terminal, sudo grub to bring up the grub config. after that you will need to type in some commands...

root (hd0,0) //points where ubuntu is. first hd, first partition. yours may be different.
setup (hd0) //installs grub onto the first hd
quit //quits grub config
exit //exits terminal

after that, you will see that grub is back on, but it will only list ubuntu. you will then need to edit menu.lst to have a second entry for vista (if you want dualboot vista).

sudo gedit /boot/grub/menu.lst //pulls up gedit to edit the menu file

at the bottom of this boot list file, you will need to add vista.
title M$ Windoze //name this boot option
root (hd0,1) //this hd0 is the first hd, 1 is the second partition here.
makeactive //self explanatory
chainloader +1 //loads ntldr if you choose this boot option. this is required.

alternatively, you may want to use the vista loader. use easybcd to edit the bcd file. this program can help you add ubuntu to the vista loader easily. this method is probably easier.

awesome, thanks a lot man. I'm not particularly fond of grub as every method I have tried to use to edit it, has failed for some reason.

if you have vista on it already, but the bootloader is either messed, or grub is the boot loader, you can use vista's install dvd to do a startup repair. that will repair the bcd and give you the vista loader. once that is done, you can use easybcd to create an entry for the ubuntu partition.

with this method, you will be using the vista loader for dualbooting. some prefer it this way as easybcd is really easy to use.
