I am trying to install 12.04 alongside my existing install of Windows 7 on my Lenovo IdeaPad laptop. I decided to go for the 64-bit version since I have 6 GB of RAM.
I've followed this guide to make sure everything worked properly and to use the Windows 7 bootloader. However, even after following the guide all the way through, I am not able to start Ubuntu in any way. When I choose Ubuntu from the startup menu, I get to a command line version of grub (if using EasyBCD default settings) or an error (if manually setting EasyBCD).
I tried reinstalling Ubuntu in any possible way: I shrank the Windows partition with the Win7 utility; I tried letting the Ubuntu installer create the partition or creating them manually as the guide specifies. Nothing works and in no way I am able to start Ubuntu.
At this point, I still have 170 GB of space that I squeezed out of my hard drive and I can start over once again, but I think the guide I was trying to follow has something wrong, or I am missing something. Can anybody point to a solution?
