Bios is finding the XP drive as the first bootable device.

Try marking XP partition Inactive , then run startup repair 3 times from the 7 dvd.

Win7 BCD: Unable to modify via CP or using EasyBDC

I'm new to Windows 7.


I'm currently running a dual boot system, Win7 & WinXp. I have WinXp on an 80gb IDE drive, disk 0, partition 0, and Win7 on a 500gb SATA II drive, disk 2, partition 0. I have my BIOS pointed to start from disk 2, at which point Win7 boot manager comes up and offers me 3 choices:


1. Windows 7
2. Windows NT/2000/XP/2003
3. Windows NT/2000/XP/2003


I can boot into the Windows 7, the current/default OS with no problems. However, in selecting either of the legacy OS's I receive the following error message “Windows could not start because the following file is missing or corrupt: <windows root>\system32\ ntoskrnl.exe. Please re-install a copy of the above file.


The initial install is a Windows 7 Ultimate over a cloned disk 0, 80gb HHD of WindowsXp using Norton Ghost 15.0. I can boot into either system as long as I set in the BIOS the respective drive as primary of the OS I want to load up. As a side note, when booting into WindowsXP on disk 0, an error message comes up: “invalid boot.ini, loading from c:\windows,” of which I later discovered was from Win7 boot manager modifying this file and renaming it Boot.BAK. Also, in booting up XP I go through a different Win7 boot manager offering of :


1. Early Version of Windows
2. Windows 7
3. Windows 7
4. Windows NT/2000/XP/2003
5. Windows NT/2000/XP/2003


As before, I can log into WinXP selecting 1, 4 & 5 but not without the boot.ini coming up 1st. Selecting either 2 or 3 causes my computer to reboot.


I've read and re-read thru this post “How to Use The BCDedit Command. I've right clicked and “Run As Administrator” and have also downloaded the “Elevated Command Prompt.” Below is a before and after snapshots of running BCDedit and indicating it was successful. However, and the reason for this post, is that it wasn't successful in that running BCDedit after the changes indicates no edits took affect, even after re-booting my system.


I've trying running EasyBCD 1.7.2 under WindowsXP but everything is grayed out or not able to selected anything. It opens and I can view boot loader but I can't modify anything, just exit. And under Win7 after installing EasyBCD 2.0 beta-build 82 via administrator run, I get the following error message: “the application was unable to start correctly (0xc000007b).

Hi,

D/l a copy of Easybcd 2.0 EasyBCD 2.0 Beta Builds - The NeoSmart Forums

Install it on 7.

Go to Add/remove entries and remove the XP entries.

Add a new Xp entry and let Easy autoconfigure.

Resolved: Win7 BCD:Unable to modify via CP or w/ E-BDC

After downloading the 2.0 beta of EasyBD I also came across another post about Zonealarm (I'm using the Home edition) interfering with EBD. I uninstalled Zonealarm and installed EDB 2.0 beta, started it without any error messages this time, and modified my BCD without any problems.

I've never understood the following near the start of your tutorial:

"Bcdedit edits a file called bcd , which is located in Windows 7's hidden partition under \boot\bcd."

And why don't I understand? because my C:\ drive shows a \boot folder.

True that \boot\bcd has the attributes of ash.

But the file is there. Now I haven't worried with investigating the recovery partition for a bcd file.

Next question:

What is the difference between a GUID and a UUID?

I know that by any other name a rose smells as sweet but I'm just curious.

Dwarf,
Perhaps I should have worded my question differently.
The documentation that I have, downloaded from MS, uses GUID rather then UUID. My question of the author of the tutorial is why he has chosen to use UUID as opposed to GUID. Sometimes MS changes the currently blessed terminology.

As explained in the first link, GUID is Microsoft's implementation of the UUID standard.
