Windows 7 Ultimate x64 SP1 Dual Boot with Windows Serve 2012 R2
 
 

i have a bizzare problem .
to make it short . i had/have dual boot system . xp sp3 32bit was initally instaled and later upgraded ram so needed a 64bit os so i installed win 7 ulitmate 64bit as a dual boot on seperate partition. later after few days i wanted to remove xp 32 bit and replace it with xp 64bit. as i love it more then 7 somehow. so i downloaded a program Wintoflash and it crached my system and i could not log onto my system. long story short i played all sort of bootrec bcdedit etc commands .. things were more complicated that i could load windows xp and not 7 and two or my data partitions were not shown . so had to do mbr recovery . ..

now situations is that i can access/login to either windows xp sp3 32bit or Windows 7 64bit .. but my boot menu shows 4 entries . two of them are functional and two are non functional . as mentioned earlier i couldnt load win 7 so i downloaded easybcd played with it and i had no optical drive so i used the easybcd feature which lets us list an iso in the boot entries and boot from it . i added a windows 7 recovery environment iso to it ..
and among the 4 entries this is one ..

the dysfucntional entry is for windows 7 ..

as shown all the entries below in pic .




this is the result of selecting the dysfunctional window 7 entry



and these are the situations in windows xp startup and recovery tab and the boot.ini file and the easybcd (shown in pic uploaded below )

and these are the situations in windows 7 startup and recovery tab


now as it is obvious from above posts that 4 entries are shown in the boot list and windows 7 bootloader shows only 1 inside windows . who the hell is injecting those entries ? i know that neo one is injected by me using easybcd in xp but as u see in above pics from xp its not shown there now so how is it still lingering here ?

here is the test form easybcd that i just got from it in windows 7
There is one entry in the Windows bootloader.
Quote:
Default: Windows 7 Ultimate (recovered)
Timeout: 30 seconds
Boot Drive: C:\

Entry #1
Name: Windows 7 Ultimate (recovered)
BCD ID: {default}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe

When I do a Bcdedit the results are identical to yours with the exception that I am using Win 7 Pro.

I solved it.
So are you asking for help or telling me something. If u are also having the same issue as I had then just search for my last reply in another thread that will solve it. I m on cell phone so can't copy paste that solution here


Edit
Here is the solution

What I did is that i installed easybcd on Windows 7 and went to bcd backup repair tab checked reset bcd configuration clicked performance action. Then I. Add new entry tab I added xp and 7.now all is well.


Except that windows 7 is very slow to boot now.
