Windows 7: Win7 Multi Boot Problem

Win7 Multi Boot Problem

Guys,
I have a multi-boot set up (both Windows 7) on one of my PC's. My original OS was getting buggy from all of the install and de-installs over fours years. It was a great idea. It worked great. It's like getting a new PC. Takes half the time to boot.
After a while I was getting tired of selecting which system I wanted so I went in to msconfig, boot selection, and removed the old system thinking I could just add it back in if I wanted.
Now I need to boot in to the old OS again so I went back into msconfig and see there is no way to add it back. I went into BIOS and changed the disk priority and rebooted.
Still went to the new OS.

Any ideas as to how I could get my original system to boot?

See attached image of Disk Manaager.

Thanks!!

Try using BCDedit or Easy BCD to add it back.

No, I don't want the boot manager and menu on E: Not sure how that happened. It was on C: before I started all this madness. Will "BCDBoot E:" put the Manager and menu back on C: and make C: bootable again?

Thanks for the help.

C and E are just driver letters. They are defined by the current running OS. You are running new Windows 7 OS now, so that's called C now. The old Windows 7 is called E. See your screenshot.

1-boot in the new Windows 7 (as you do now)
2-do #3 from within elevated command prompt Elevated Command Prompt

Successfull? System has old Windows 7 as boot entry again?

Thanks for doing the leg work Kaktussoft, I didn't have time this morning to give detailed information for the OP.

Before I start this I have one question.. Kaktussoft's reply " C and E are just driver letters. They are defined by the current running OS. You are running new Windows 7 OS now, so that's called C now. The old Windows 7 is called E. See your screenshot." Is wrong. The new OS is on E not C. Does this change anything?

Thanks for the help!

Did you install new Windows 7 after booting and logon to old Windows 7? If you did... C was already in use and D as well.... it did install in a partition called E.

Do #3 from within elevated command prompt Elevated Command Prompt

Successfull? Reboot... do you see boot menu with the two Windows 7 options?
To rename the description of the current booted OS. (do it in elevated command prompt):

Code:
 
bcdedit  /set  {current}  description  "Windows 7 new"

One more question. Should #3 be "bcd boot E:\windows" since the boot menu is now on E not C?
