Windows 7: Windows 7 and XP dual boot - Win 7 partition not booting anymore

Windows 7 and XP dual boot - Win 7 partition not booting anymore

Had win7 and XP working on dual boot with easyBCD for months. Then had to wipe another drive so removed all connections in PC and wiped totally unrelated drive, linked everything back up again, and now windows 7 won't boot up and the boot menu has gone.

I have three hard drives - one backup, one for XP, and one with three partitions including win7.

When i set the BIOS boot order to the XP drive it boots up ok, when i set the order to win7 drive it gets to 'verifying dmi pool data' then asks for a boot cd.

I have rebuilt the MBR using partition wizard. As you can see, the XP drive is active and primary. I cannot seem to set the win7 disk to be primary or active. It also tells me it cannot find a windows installation on the drive even though it is loaded onto E:

I have tried loading the win7 dvd and running the start repair several times but it does nothing.

I don't get what happened as all i did was remove all the hard drive connections, then connect them back up a few hours later.

Any ideas? I have spent four hours on it already and need help before i smash the thing up!

fixed it! woohoo

this worked for me....

go here Visual BCD Editor - Windows 7/Vista
and get the VBCDE and follow instructions here Dual-boot Repair Windows 7/Vista
for automatic repair.

fixed my setup in half a second. machine booted back into windows 7 directly, then used easyBCD to add the winXP option to the boot menu and back in business. Both XP and Win7 on boot menu and both working fine. Woohooo!
