Under XP, you can directly modify boot.ini to add a GRUB4DOS entry, but it's not that simple under Vista.

Since both the company and home computers are XP + Vista, I experimented with GURB4DOS functions many times a few days ago. Previously, I added this menu item manually. Today, I made a batch script and share it. To prevent newbies..., I added some junk at the front.

The following batch script will automatically add the GRUB4DOS boot entry to the Vista boot menu:

===== Add_GRUB4DOS_Menu.bat =====

@echo off
echo This batch script automatically adds the GRUB4DOS boot entry to the Vista system's boot menu.
echo If it's not a single Vista (there are also XP, 2K), it must be run under Vista.
echo Also, it needs to be run as an administrator.
echo .
pause

ver | find "6.0." > NUL && goto START
ver | find "XP" > NUL && goto XP2K
ver | find "2000" > NUL && goto XP2K
goto EXIT

:XP2K
echo Cannot run this batch script in WinXP or Win2000.
goto EXIT

REM ============= The above content is purely...... ==============

:START
cls

bcdedit | find "\grldr.mbr" > NUL && echo There is already grub4dos in the boot entry, no need to install repeatedly.&& goto EXIT
bcdedit /create /d "Boot From GRUB4DOS" /application bootsector >GrubID.txt
rem The above GRUB menu name to be added can be modified to "GRUB For DOS", "DOS + GHOST", etc.

for /f "tokens=2" %%i in (GrubID.txt) do set GrubID=%%i
del GrubID.txt > NUL
bcdedit /set %GrubID% device partition=%SystemDrive%
bcdedit /set %GrubID% path \grldr.mbr
bcdedit /displayorder %GrubID% /addlast

echo .
echo The above should have 3 "Operation completed successfully."
echo .
echo Please copy grldr.mbr to %SystemDrive%\ by yourself
echo .
echo Please copy grldr to C:\ by yourself
echo .
echo According to needs, please copy other related files by yourself, such as menu.lst, fonts, memdisk.gz and background pictures, etc., to the corresponding positions.

:EXIT

====== THE END =====
Everyone may use GRUB4DOS in different ways, so there is no automatic copying of grldr.mbr and other files. It's still safer to copy them yourself.

Give it a support. There is still room for further improvement.

There is a problem with the batch script in the first floor: when deleting this menu item, manual operation is required:
Enter CMD, run bcdedit, find "Real - mode boot sector", copy the "identifier" (the string containing curly braces) below it, type bcdedit /delete and paste the just - copied content, and press Enter.

For convenience, I slightly modify Add_GRUB4DOS_Menu.bat, and then can use the following Del_GRUB4DOS_Menu.bat to automatically delete the GRUB4DOS boot item.

===== Add_GRUB4DOS_Menu.bat =====

@echo off
echo This batch script automatically adds the boot item of GRUB4DOS to the boot menu of Vista system.
echo If it is not a single Vista (there are also XP, 2K), it must be run under Vista.
echo In addition, it needs to be run as an administrator.
echo .

ver | find "XP" > NUL && goto XP2K
ver | find "2000" > NUL && goto XP2K

rem The above GRUB menu name to be added can be modified to "GRUB For DOS", "DOS + GHOST", etc.

for /f "tokens=2" %%i in (%SystemRoot%\GrubID.txt) do set GrubID=%%i

bcdedit /set %GrubID% device partition=%SystemDrive%

:EXIT
====== THE END =====

===== Del_GRUB4DOS_Menu.bat =====
@echo off
bcdedit | find "\grldr.mbr" > NUL && goto START

echo The grub4dos item is not found in the boot menu.

if not exist %SystemRoot%\GrubID.txt goto ERROR

goto EXIT


:ERROR
echo %SystemRoot%\GrubID.txt is not found, and automatic deletion cannot be performed.

Since it is for the convenience of beginners, please be sure to provide links to relevant tools!

I think you should make this batch processing a general XP 2003 VIST multi-boot menu (excluding LINUX)

The requirements are as follows:
- Automatically identify how many systems this computer has
- Write a mutually bootable menu in the system file (boot)
- General for XP 2003 VIST
- Do not damage the original boot menu
- Have a safe uninstall function

I think it shouldn't be difficult for you!! Hehe, after writing it, I will pin this post for a while.

The first one can basically be ignored. The following three are not a big deal.
The last one is difficult because I don't know how to delete specific lines in the file for the time being.
If a backup file is used to replace it, then all changes made to the boot menu during this period (such as newly installed systems or manual modifications) will all disappear, which is not appropriate.

Also, it seems that no one is interested in this topic. I'd better not continue to mess around.

If every little thing requires a lot of people to be interested, I'm afraid there will be a lot of disappointment.

Why don't you prove that you can do it, why don't you find a way to make more people interested in this topic?

For XP/2003, it's very easy with the system's own bootcfg command
pushd %SystemDrive%\
set btini=boot.ini
attrib -s -h -r %btini%
FIND /I "c:\grldr" %btini%
::If not, add a startup item c:\grldr="grubdos"
IF "%ERRORLEVEL%"=="1" @echo.c:\grldr="grubdos">>%btini%
for /f "tokens=1,2* delims=: " %%i in ('bootcfg/query^|findstr /I /n "c:\grldr"') do set /a hang=%%i - 2
for /f "tokens=1-5 delims=: " %%i in ('bootcfg/query^| findstr /i /n "Startup Item"') do if "%%i"=="%hang%" set qdid=%%l
bootcfg /Delete /ID %qdid%
pause

Because I have not used VISTA, so I don't know about VISTA

Thanks!

A week or two ago, I also wanted to try to boot GRUB for DOS through the VISTA boot manager, and then saw this page introduction on the Internet:
http://grub4dos.sourceforge.net/wiki/index.php/Grub4dos安装和启动

I executed the following three statements under VISTA at that time:
bcdedit /create /d "Start GRUB4DOS" /application bootsector
bcdedit /set {id} device boot
bcdedit /set {id} path \grldr.mbr
bcdedit /displayorder {id} /addlast

Among them, {id} I replaced with the output content of the first command, but I did not change the boot after the second command, just entered it as it was. As a result, it could not be booted. I thought at that time that the grldr.mbr file was problematic...

Today, I saw this post and changed that "boot" to "partition=C:" and it worked!

Just happen to need to study

These days I'm just concerned about this. Just right, copy it back and study it well. Thanks.

--------------------------------------------------------------------------------------------------
After reading, I want to ask a question. I'm relatively green, please forgive me.

In the past, when using XP, I could add c:\grldr="Start GRUB4DOS" in BOOT.INI, and then only need a grldr file, no need for the grldr.mbr file. Why in Vista do I need to bring this file? Is there a way to be the same as before, only need a grldr, not bring grldr.mbr?

Actually, although Vista and Win7 use BCD, they will still read boot.ini (if it exists). Therefore, the old method can be continued. Write a boot.ini in the root directory of drive C yourself:



c:\grldr.mbr="grub4dos"

Please note the quotes above. For XP, quotes are not needed, but they are required for Vista and Win7.
Then copy grldr and grldr.mbr to the root directory of drive C.
