I possess a lenovo x120e laptop powered with AMD Fusion E-350 processor. As I wish to have a dual boot machine, I installed Ubuntu desktop 11.10 amd64 along side Windows 7 on it. The installation was successful but the while booting instead of grub giving me options to choose which os to boot, my machine directly boots Windows 7. I have tried the steps mentioned at the following link
https://help.ubuntu.com/community/X120e
I successful installation had Legacy and UEFI boot enabled. When I tried installing with only Legacy boot enabled, the installation halts in between.
It would be deeply appreciated if someone could help.
