Hi, I have been using ubuntu for 4 yesrs and never see problem like this.
I recently assembled a new pc. just put win 7 on it. next step is put ubuntu on it because I am mainly using ubuntu daily . No matter I choose custom install or default install , when it is done, restart, computer only boot into win 7 directly , the grub menu never shows so I have no chance go into ubuntu. I installed easyBCD in win 7 it won't help neither.
please see if any one know this problem.
I don't want to use win 7 everyday.

I am trying a similar setup, except that installation fails to install Grub onto /dev/sda5 (a partition i made for /boot) see this thread: http://ubuntuforums.org/showthread.php?t=1773665
I tried adding the entry for Ubuntu using EasyBCD but it just takes me to a prompt: grub>

@zghawking Please start your own thread & include EasyBCD in title and output of boot script. I do not know Easy but a few here do.

Post this so we can see what is installed where.

no, I didn't hold any key. I tried use this guy's help to manage to get the grub 2 shows :
http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7
I applied his #2 method, I have to regenerate grub.cfg file because withtout doing it , grub only shows a grub=>.
when I regenerate the grub.cfg. after I type "chroot /mnt update-grub
", system only report it found windows 7, and then I reboot, win 7 is back as a menu item , but still no ubuntu 11.10.
This is really funny because I did it in ubuntu live cd mode. I use ubuntu live cd to get my win 7 back but still can't load into ubuntu 11.10
