Thanks, I forgot the extented counted as a primary.

Now I'm thinking I'll convert the utility partition to the boot partition. I don't beleive it currently contains anything relating to booting or has anything to do with the dell media direct program. Its just a diagnostic utility that I never use, so I guess I could delete whats on it and use it as a boot partition.

Its 47 mb in size, is that big enough for the boot manager?

Not sure about that - 7 creates a 100mb partition - though it occupies only 32mb of that, if I remember correctly.

If you are adventurous you could try it and see.

If you are going to experiment - I suggest you make backup images of your partitions and MBR - to restore in case you hose something.

I would use a 3rd party tool rather than Windows Backup.

On that note, this project is officially dead. Wanted to test windows 7 backup w/o it including the partition (XP) where the boot manager is, but at this point its really not worth it. Next time I install Windows 7, I'll test it out.

Thanks every one for the help,

I'll play around with moving the boot manager (for the learning experience) and testing 7's recovery on the next install.

Windows 7 Ultimate 64bit

To move your (native, bootable) Win7 VHD to a new drive, is the same true? ie Can I do this?
  1. Connect new drive (as external)
  2. Format new drive (active partition)
  3. copy boot (DIR), bootmgr and the VHD, and export BCD to newDrive:\Boot
  4. Install new drive (locally)
  5. Boot into (existing VHD) OS on new (internal SSD) disk
So your GUIDs stay the same?

Is it THAT easy?!

Been (virtually) burned a few times already

Thanks guys

Windows Vista

Hi all. I wonder if you could help me with Vista. I have boot loader located on old hdd with XP and can't move it with command bcdedit /export X:\boot\bcd - it says access denied. I tried to open access but that doesn't work. How is it possible to do that? Thank you.

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.
You say to copy the boot folder, but where is the boot folder located?

Windows Boot Manager won't boot the correct drive
Hi, I installed Windows 7 in UEFI mode to an SDD and I figured it would be easy to take my old drive which also had Windows 7 installed, hook it up to a SATA port, and copy over the files that I wanted. In my BIOS interface I can select the SSD drive to boot from, or "Windows Boot Manager"....
