Windows 7: 0xc0000225 boot error after extending partition?

0xc0000225 boot error after extending partition?-Solved

So basically I have two partitions: Vista C: and Win7 D:, boot file is on C:
I had installed Jolicloud OS on my computer and it carved out a drive from my Win7 partition. later on I EasyBCD to remove grub when I figured out that it will be a pita to get my wifi working. afterwards i booted from the jolicloud installer, then used Gparted to extend the Win7 partition back to it's original size. i then rebooted, and it ran the disk repair, but now Windows 7 won't boot, giving me:
"Windows did not start correctly. A recent hardware or software change might
be the cause.

If you have aWindows installation disc, insert the disc and restart your
computer. Click system recovery options, and then choose a recovery tool.
(Startup Repair, available in some versions of Windows, can automaitcally
diagnose and fix startup problems.)

If you do not have this disc, contact your system administrator or computer
manufacturer for assistance.
I've tried to use the recovery feature on my disk, but it cannot see my hard drive and it's not able to locate a driver.

help? Windows Vista is AGONY
also: Easy BCD whe running from Vista says:
There are a total of 2 entries listed in the Vista Bootloader.
Bootloader Timeout: 10 seconds.
Default OS: Microsoft Windows Vista

Entry #1

Name: Windows 7
BCD ID: {6d574dfa-cef3-11de-a588-9966156464d7}
Drive: Deleted Partition
Bootloader Path: \Windows\system32\winload.exe
Windows Directory: \Windows

Entry #2

Name: Microsoft Windows Vista
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe
Windows Directory: \Windows
i'm going to re add the entry for 7 via easybcd. if you don't hear from me in ten minutes then you will know that this didn't work.

That boot manager should also display the option to Rollback your installation.
If the previous installation is inaccessible, try booting from your Windows 7 installation and attempt a Custom (Clean Install). You previous installation will be moved to the root of the drive in a folder called Windows.old.

well fixing the bootloader worked, but now when I log in I get a blank screen and in the corner it says "this copy of windows is not genuine".
without reinstalling, is it possible to fix this?
I'm using the Windows 7 Enterprise 90-day trial, so could by any chance it became deactivated?

In the future, use EasyBCD 2.0 beta which has automated diagnostics.

Since you can now boot Win7, put your DVD in the tray and run a Repair Install from the Win7 desktop which should correctly reconfigure the dual boot as long as GRUB is uninstalled first.

Failing this, you may need to format over the GRUB.

Grub is deleted.
I found that the problem is that 7 thinks it's on drive C:, because before I had the Vista drive set to B: in 7.
problem is, I cannot change the registry to correct this in 7, and Vista won't open hives or whatever that means.

YAY it works now!

the following is a condensed guide on how to repair this problem from a bootable Windows OS:
IMPORTANT: remember what the drive letter was when Windows worked, and find out what it is now
1. from the operational Windows OS; Run regedit.exe from Start -> Run
2. Select HKEY_USERS by single-clicking on it
3. Go to File -> Load Hive
4. Navigate to the registry file folder on your other drive. This is found in DRIVELETTER:/Windows/System32/Config
5. Select the file labeled SYSTEM. Make sure not to select the text file
6. Type whatever name you like in the Key Name field, Hit Enter.
7. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
8. Try to remember your old working drive letter, mine was drive D, and windows changed its drive letter to C. So i swapped the D and C paths in the registry; now windows knows to access the correct drive to boot.
9. To swap drives, find the drive letter you want changed, it should look something like "\DosDevices\C:" where "C" is the drive letter you need swapped.
10. Right click on the key and rename it to a drive letter that is not in use, for example, I renamed mine to "\DosDevices\Z:" This will free up the letter that you need swapped.
11. Right click on the other key and rename it to the first key's letter, for example, if i wanted the D drive swapped with C, I would now rename "\DosDevices\D:" to "\DosDevices\C:".
12. Now rename "\DosDevices\Z:" (Which was previously "\DosDevices\C:") to "\DosDevices\D:"
13. Select the folder the hive was mounted in by right-clicking it once
14. Go to File -> Unload Hive
15. Restart the computer and load your newly working OS!

Yes, you could do that.

Much easier to use the boot corrector on the free Paragon Rescue Kit Express :
