Thanks, it appears my cmd window now has sufficient authority.

At the same time, I'm not sure how to change the name of say my Windows 64 boot manager entry.

This command looks dangerous, in that a mistake could require me to re-install both my operating systems.

The output of my command looks like this -

bcdedit /enum

You can use the /export command to create a backup file of the current system store contents.

For info on the /export command, type...

bcdedit /? /export
 

Examples..
bcdedit /export C:\BCDbak
bcdedit /export C:\"BCD bak"
 
(if file name contains spaces, it must be enclosed in quotation marks.)

You can then use the /import command to restore the system store contents if any non-fatal errors are encountered.
Examples..
bcdedit /import C:\"BCD bak" 
bcdedit /import C:\BCDbak /clean
 

My dual-boot system has Windows 7 64bit and an earlier install of XPPro 64 bit. For a full description of entry identifiers, I type..
bcdedit /enum /v
 
..and I get..

For output showing names for well-known identifiers and to show what system is active (current), I just type..
bcdedit
 
..and get..

Any help, or clear as mud? ;)

*edit*
If I wanted to alter the XP boot settings, I would log on to XP and just edit the boot.ini by right-clicking "My computer" then "properties", etc.

It worked, thanks so much!

I tried to change the name on the second boot to indicate it was the 32 bit version of Windows 7, but it didn't take.

I'm still happy to just have a distinction between the two boot options.

Overall, the 64 bit seems to be doing better than I expected. My concern was the extra address space for 64 bits vs 32 would limit system performance in a 2 GB PC. There is no significant performance hit and my 32 bit stuff runs fine.

Thanks again for your help!
