Windows 7: Installed 7127, now can't boot into RC

Installed 7127, now can't boot into RC

Here's my setup, I was dual booting XP and Windows 7 RC1 7100 on two separate partitions and that was going swell.

When I found out 7127 got leaked I decided to use GParted to clear my XP partition and I installed 7127 on that partition. I can still see my files from the RC1 7100 partition but my bootmanager doesn't recognize another operating system on my PC.

Can someone please help me? Thanks.

Boot into 7100, download EasyBCD and use that to add the new 7127 install partition to the boot manager as a choice. (Use Add/remove entries on the left side.) Hit save when done. You can then go to change settings on the left to set the default OS.

Any questions, post back and good luck.

thanks for the response, but the problem is that I can boot into 7127, but now now 7100.

-edit-
theoretically speaking, can i use it to readd my 7100 to the boot manager?

Ah, ok my bad. Then yeah, you can add 7100 partition to the boot manager while in 7127 and all will be well.

thanks. i really don't know how to do that because i'm unfamiliar with EasyBCD but to spare a "let me Google that for you", I will try to figure it out on my own.

From within 7127, open an elevated command prompt, type: ( press enter after each command)

bcdedit /copy {current} /d "7100"

It will return a long number in brackets, a {GUID}.

Use the {Guid - you - got } including the brackets in the following commands

Assuming 7100 is on D: from the o/s you are currently in:

bcdedit /set {Guid - you - got } device partition=D:

bcdedit /set {Guid - you - got } osdevice partition=D:

Hi andy - glad it worked for you.

You can use any name you like in between the "".

You can use the same copy commands to add any of the NT6 o/s - Vista or 7 to any of their bcd's.
