So - earlier today I had the following config of HDDs

250GB (win XP), 500GB (win 7 - main boot option), 640GB (storage), 1TB (storage)

The win XP is an old install I never got rid of - so I wanted to get rid of it and put a new HDD in:


1TB (empty), 500GB (win 7 - main boot option), 640GB (storage), 1TB (storage)

screw it in, plug it in, turn it on!

"BOOTMGR is missing"

So i whip out my windows 7 disk and put it in, it tells me there's a startup error so I tell it to fix it. It restarts. Same problem.

Go back into win 7 disk, this time try the console with:
# BootRec /fixmbr
# BootRec /fixboot

no luck!!

check all the wires are in place - they are.

Furthermore - the Sys Recovery option on Win 7 is saying:

The following startup option will be added:
Name: Windows 7 Home Premium (recovered)
Path: Windows
Windows Device: Partition=C: (476937 MB)

Name: Windows Recovery Environment (recovered)
Path: Recovery \3cdf4578-06fa-11df-b8e2-f6104d74718d\Winre.wim
Windows Device: Partition=C: (476937 MB)

Did this:

* bcdedit /export C:\BCD_Backup
* c:
* cd boot
* attrib bcd -s -h -r
* ren c:\boot\bcd bcd.old
* bootrec /RebuildBcd

BootMGR still

ALSO (edit)

Superweird - I tried booting up the removed XP drive (no other drives attached) and it came up like it used to with

Choose an operating system:

Earlier Version of Windows
Windows 7

Windows XP appears to boot fine.

Please help me get Windows 7 working!!

Ok - this has got really really weird

I set up the old config - without the new 1TB drive, and with both the XP and win7 drive and it all works -

Why is the Windows 7 drive needing the Win XP drive to work?

sounds like when you installed win.7 it sared the info between HDD's needing both HDD's for windows to boot. I'd say fresh install with only the OS intended HDD connected. Not even close to the most knowladgable on this site, but a good place to start since you have no info. on your new HDD yet. Good Luck!!

For those who meet similar problems and have no Recovery disk. BootSuite is another awesome option to choose.
