i have 3 HDD, 1 for win7 ,1 for win2008 ,1 for my Vmachines
after installing the win 2008 R2 ,iam facing too much performance issues,too much slow ,compared to what it was
win 2008 R2: is super cool ,its runing smooth ,but win 7 start having some startup slowness
i know that i need to delete the win2008R2 from the BOOT.ini ,but :

Doesn't seem right that a non-running OS is slowing your machine unless you ran out of disk space. You can remove entries via bcdedit tool or EasyBcd

Hi,
I am a bit confused about your description “after installing the win 2008 R2 ,I am facing too much performance issues” and “win 2008
R2: is super cool ,its runing smooth”, seems they are conflicting.
From Windows Vista, there is no boot.ini, it’s been replaced with Windows Boot Manager, you can run command “bcdedit /v” to view the
system installed on your computer; you can also type “msconfig” in Run to start “System Configuration” window and then navigate to Boot tab to check the boot information.
There are two scenarios in your environment:
1. The Windows 7 disk is the first disk(disk 0), if you install Windows Server 2008 R2 after Windows 7
If so, you can perform the following steps:
1.1 Use “bcdedit” command to delete the boot information of Windows Server 2008 R2, you can also run “msconfig”
to delete it with GUI.
1.2 Format the Windows Server 2008 R2 disk
1.3 Format the 3<sup>rd</sup> HDD if you don’t need those VMs.
2. The Windows Server 2008 R2 disk is the first disk, if you install Windows 7 after Windows Server 2008 R2
If so, you can perform the following steps:
2.1 Unplug the Windows Server 2008
2.2 Because of the boot information was wrote in the Windows Server 2008 R2 disk, you have to use a Windows 7 installation disk to
repair the startup of Windows 7. For more information, you can check the following link.
http://www.intowindows.com/how-to-easily-repair-windows-7-boot-problems-using-startup-repair/
2.3 You can connect the Windows 7 disk to port 1 on the motherboard and connect Windows Server 2008 R2 disk to other ports and then format it, also the 3<sup>rd</sup> HDD.
By the way, the following post discussed the similar issue, you can refer to:

Hi,
so i removed the Win2008 boot from the boot informationusing msconfig
and then restarted the pc
format the win2008 partition
installed win 7 again
i noticed a huge slow performance ,when i try to boot windows
so i tried to disable the same HDD that has the win 2008 partition and the VM partitions
and like magic now i can boot to windows within 50 sec :)
iam going to check why i am having this slowness on when i enable the 3rd HDD ?
any help would be great

Hi,
I am a bit confused about your description.
It seems that you got some performance if you install Windows 7 on the Windows Server 2008
disk(the second disk), if so, I suspect that there are some issue with the second hard disk. You need to check the setting on the hard drive or replace it with a new one.
By the way, as you mentioned that you have another Windows 7 installed on the first hard disk, so if you want to remove the boot information
of the Windows 7/Windows Server 2008 installed on the second hard disk, you can login to the Windows 7 installed on the first hard disk and then remove the unneeded boot information from Windows Boot Manager or through bcdedit command.
Best Regards,
