Solved Win7 Multi Boot Problem

[Pete491]

Guys,
I have a multi-boot set up (both Win7) 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.

To add win7 from C to the bootmenu:

bcdboot  C:\windows

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 win7 OS now, so that's called C now. The old win7 is called E. See your screenshot.

1-boot in the new win7 (as you do now)
2-do #3 from within elevated command prompt http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html

Successfull? System has old win7 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 win7 after booting and logon to old win7? 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 win7 options?
To rename the description of the current booted OS. (do it in elevated command prompt):

bcdedit  /set  {current}  description  "Win7 new"

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

Bootmenu and bootmanager are on C. See disk management screenshot. You are currently running win7 OS from E.

You have to add win7 on C to the bootmenu. So do #3 from elevated command prompt.

 

[Pete491]

Success!

Guys,

All is good.

Thanks!!!

Guys,

Glad you solved it. You only did #3 ? Can you easily see which bootmenu choice is OLD and NEW?

EasyBCD

I took a look at EasyBCD at your suggestion, downloaded, installed, added the other OS, rebooted and everything is perfect.

Thanks!!!!!

I have to say that EasyBCD is a great program. I was able to solve my problem in about 2 minutes. All I need to do was add the other OS, change the name, save, reboot and that was it. I could then select the OS I wanted when booting.

VERY easy to use.

Glad it worked out for you.

You can go ahead and mark this as solved so other people can easily find solutions to similar problems. To do that just go to the top right area in or near Thread tools (forgot exactly where since I don't make too many threads ).

 

[Kaktussoft]

It actually does same as bcdboot command (sort of). But did you test??? Is "resume from hibernation" working? Is "repair your computer" working in advanced boot options?

 

[Pete491]

Resume and repair works!

I'll mark it as solved.
