Re: Windows 7 boot manager editing questions

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..
Windows Boot Manager

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!
