I assume 2008 R2 is on F?

Bootmgr and the Boot folder containing bcd that are currently in use are on E.

What does the Easybcd View show?

That is vey odd.

Your new drive ( Disk0 ) is first in the Bios boot order. The system reserved partition was created by the R2 installation.

Your old installation of 2008 appeared in bcd , but not the new R2 installation?

what if i switch the sata cable on the mother board with the disk "0" to disk "1" and disk "1" to disk "0" will that change the issue?

If you do that - Disk 1 will be first in Bios boot order - presumably as it was before you added the new drive.

Disk 1 will then be the boot drive, and C will the System partition.

You will be then using bootmgr and the bcd store on C.

You can add an entry for R2 manually to the C bcd store like this:

Open an elevated cmd prompt, Type ( press enter after each cmd)

bcdedit /copy {current} /d "2008 R2"

You will get a response saying that a new {GUID} was created successfully. It is a long number in curly brackets - use that, including the brackets, in the cmds below

bcdedit /set {your_new_GUID_here} device partition=F:

bcdedit /set {your_new_GUID_here} osdevice partition=F:

( If you prefer to use Easybcd - it does the above cmds for you)

i used Easybcd 2.0 earlier, i now have 1 more entry since you have been helping , but if this works i will delete the bad one, thanks for your help.

There are a total of 3 entries listed in the bootloader.
Default: Microsoft Windows Server 2008
Timeout: 30 seconds.
Boot Drive: C:\
Entry #1
Name: Microsoft Windows Server 2008
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe
Entry #2
Name: Microsoft Windows Server 2008 R2
BCD ID: {cf50bb3b-b210-11de-8f38-00508d98f403}
Drive: F:\
Bootloader Path: \Windows\system32\winload.exe
Entry #3
Name: 2008 R2
BCD ID: {cf50bb3c-b210-11de-8f38-00508d98f403}
Drive: F:\
Bootloader Path: \Windows\system32\winload.exe

Otherwise, you could try running startup repair by booting the dvd - at the Install Now screen , select Repair My Computer ( it's at the bottom of the screen ) - this time with Disk1 first in boot order.

I would give it 3 runs as it only fixes one thing at a time.

Hope it helps

you fixed it, the lines that i add to the bcd fixed it, after i did reboot i still would not work, so i tried boot repair startrep.exe, and this time it fixed it, there was something i wasnt doing to the bcd that wouldnt allow me to proceed, but it is all good now.


thanks
