Hi Tblount,
Thank you for your speedy reply. Actually 7 never disappeared from Easy BCD's boot list within the program itself. What I mean was that it disappeared from the actual boot list when I start up my computer. I followed your advice anyways and removed then added 7 back on to EBCD. Still no results.
Here are a few odd things that I didn't clarify before:
1) When I first installed 7. My Vista disappeared. I solved this problem by re-activating my Vista partition, installing EBCD and adding Vista to EBCD. All of this was done in the 7 partition. After this everything worked fine. I've used 7 multiple times via the boot menu since then.
Now keep in mind that by this point I have 2 versions of EBCD installed, one in 7 and one in Vista.
2) When 7 disappeared from the start-up boot list today, I opened up EBCD in Vista for the first time in ages and see the following message: "Unfortunately, EasyBCD could not automatically detect the drive letter of your boot device. This can be caused by a non-standad MBR, use of a 3rd-party bootloader, or a failed Windows Vista install...."
3) When I manually chose the correct boot drive as C (the Vista partition), I was able to start EBCD. At this point, when I check the View Settings tab the 7 boot is marked with the drive letter 'U'. I got confused, and removed and added 7 back to the list with the correct letter E but behold! In 'View Settings' it still says U.
Any more insights?
