Windows 7: No Boot From Windows 7 Drive

No Boot From Windows 7 Drive

Hello folks. I was hoping to get some help with the below. I have been reading various forums, and have found helpful tidbits, but am not clear on the solution for me, or if there even is one short of starting over.

Scenario: Prior to installing Windows 7, I had two IDE drives. XP is installed on the master and the second drive is slaved to the first. I purchased a new SATA drive for my Windows 7 installation. I do not remember if I altered the hard drive boot order in the BIOS at this time. I then booted from the install DVD and installed Windows 7 with no apparent problems.

Problem: The Windows 7 drive is not bootable. It gives me an error saying that it can't boot from the device and to press any key to retry. Initially, I thought I had to have the install DVD in the drive but I've since discovered that I can boot from my master IDE drive (XP drive) as well. When either of those drives are first in the boot order, I am presented with the menu that allows me to choose 'Older Version of Windows' or 'Windows 7.' Either works just fine. If I have the master SATA drive (Win 7) first in the boot order, then I get the error.

What I've tried: I have tried running the repair utility multiple times, but it finds no problems. I have tried using bootrec to locate "missing" Windows installations, rebuildbcd and fixmbr, but scanos shows no results, and the other two say they work fine but there is no change.

Assuming I don't want to use a third party app (I will if I have to, but I'd really rather avoid it.), is it possible to fix this? It's effectively working at the moment, as I can still boot to Windows 7, but if I later want to pull the Windows XP drive, I'm going to have problems.

Any help is welcome. I can follow instructions pretty well. I'm relatively tech savvy (I've worked in application support roles for years.), but OS problems of this level are outside my realm of experience.

Thanks.

I"m not clear on your problem.

In paragraph 3, you say you can't boot to Windows 7.

In paragraph 5, you say you can.

Can you clarify??

yes this is possible to fix without reinstalling Windows. but

if it's not too much trouble, maybe the best option for you is to unplug all of your other drives except for the one you want Windows 7 on and then reinstall.

actually, he already did clarify it. If he changes the boot order or unplugs one of the drives it won't boot. It's because the computer is booting from a disk other than the one Windows 7 is installed to.

I can. I was hoping to avoid it. I've already spent some time reinstalling applications, some of which gave me trouble that I'd rather not go through again.

Would it not be wise to try EasyBCD in the Win7 operating system first and see if EasyBCD would pickup the other XP operating system which would then create a dual boot loader?

I had a similar problem when I installed a SSD drive and wanted to boot on it... this post helped.

Copy bootmgr to the 7 drive. Then copy the boot folder to the 7 drive, ignoring the warning that it can't copy bcd and bcd.log. Just tell it to skip them.

Then do from elevated command prompt:

bcdedit /export X:\boot\bcd


where X is your 7 drive.

Change bios to boot from 7 drive and you should be good to go.

As a side note, you can take ownership of the boot folder and then delete all the language folders inside that do not apply to you. All that is needed to keep is one folder for your language (en-US), the fonts folder, bcd, bootstat.dat and memtest.exe.

Also, your Win 7 partition should be set as active.
