Windows 7 Special program booting

cveirs · Feb 3, 2011

I'm changing computers with different OS, windows xp Home to Windows 7 . I need to put a string into the BCDedit to change my boot at startup.
In Windows xp I had in the boot.ini

[boot loader]|
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\Windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\Windows="Microsoft window xp Professional"
multi(0)disk(0)rdisk(0)partition(1)\Windows="Microsoft window xp Professional 512Mem" /maxmem=512

I don't know how to edit this into the BCD file? Could you please help me with this I need it to run an office program that only runs on 512meg

Thank you for your time on this matter Charles

Is it possible to e-mail me the answer?

Charles, Moving from Windows XP to Windows 7 involves a shift from the boot.ini configuration file to the BCD (Boot Configuration Data) store for managing boot options. To set up a similar configuration in the BCD, you would use the bcdedit command in Windows 7. Here's how you can set up a similar configuration in the BCD store:

Open Command Prompt as Administrator:
Click on the Start button.
Type "cmd" in the search box.
Right-click on "cmd" and choose "Run as Administrator."
Add Windows XP Entry:

To add the Windows XP entry, you can use the following bcdedit command:

Code:

plaintext bcdedit /create /d "Microsoft Window XP Professional" /application osloader

Set Timeout:
To set the timeout to 30 seconds, you can use:
Code:
```
plaintext bcdedit /timeout 30
```
Set Default Entry:
You can set the default entry to the one you created using:
Code:
```
plaintext bcdedit /default {new_entry_guid}
```
Replace {new_entry_guid} with the GUID of the new entry you created.
Adding Memory Limit:
To set a memory limit for the entry requiring 512MB, you can use the /set option:
Code:
```
plaintext bcdedit /set {new_entry_guid} truncatememory 67108864
```
Here, 67108864 corresponds to 512MB in bytes (512 1024 1024).
Finalize:
Reboot your system to ensure the changes take effect. Since writing commands is involved in this process, I can't send an email directly. You can copy these instructions, paste them into a document, and save it to refer to when making the changes on your new Windows 7 system. If you encounter any issues or need further assistance, feel free to ask here. Good luck with setting up your system for the office program requiring 512MB of memory!
