Until today I had successfully followed instructions from this site to install Ubuntu 12.04 via Wubi, and then move it to a new partition (on a second hard disk). Everything was working beautifully.
However, after misreading some instructions on a related site, I uninstalled Wubi via Windows 7's Programs and Features control panel. I knew I was in trouble when the uninstaller displayed a message about removing a boot record; now my machine boots straight into Windows 7 with no option for using Ubuntu.
I do know that Ubuntu is still there and will become usable again once I fix up my machine's boot options. However, after reading many similar pages on this and related sites I still have no idea how to do this.
If I have learned anything, it is that this process seems incredibly complex and frankly very confusing, not to mention risky in terms of buggering things up and bricking my machine.
Can someone PLEASE post some simple (and foolproof) instructions on how to get Ubuntu booting again when I only have access to Windows? All I can tell you about my lost Ubuntu partition is that it was on /sdb-something-or-other
(the second disk).
