I got a new acer laptop loaded with windows 7 Professional. i installed Ubuntu 12.04 from a usb drive and it has been installed. but when i boot my pc there is no grub menu which helps me to choose between ubuntu or windows 7. windows 7 directly loads ub without any grub menu or reference to ubuntu.
I tried reinstalling grub on my pc using the live usb but it was unable to write the grub to my harddisk. i had mounted all the partitions.
I have not been able to boot into the ubuntu installed on my harddisk. though its working fine from the pd.
My laptop model is acer travelmate p643, i3 processor 4 gb ram and intel hd 3000 graphics..
Some Help would be appreciated
