Solved "BOOTMGR is missing" error in Windows 7 OS (Rev: 1.0)

After the Dell Optiplex GX620 pc with Windows 7 Enterprise x86 Operating System (OS) was powered on and had completed the Power On Self Test (POST), the "BOOTMGR is missing. Press Ctrl+Alt+Del to restart" error message appeared. I performed the below to solve the "BOOTMGR is missing" error:

1. Booted up the Dell Optiplex GX620 pc from the Windows 7 Enterprise DVD. When the "Press any key to boot from CD or DVD" message appeared, simply press any key. After Windows 7 had finished loading files, it will start Windows. Kindly click "Next" when it prompt the 'Enter your language and other preferences and click "Next" to continue'.
   
   
2. Clicked the "Repair your computer" options. At the "System Recovery Options" dialog box, I chose the "Windows found problems with your computer's startup options. Do you want to apply repairs and restart your computer ?" and clicked the "Repair and restart" button. After a while, the pc restarted but it still had the "BOOTMGR is missing" error.
   
   
3. Hence, I boot the pc from the Windows 7 Enterprise DVD again. I clicked the "Repair your computer" options. At the "System Recovery Options" dialog box, I chose the "Use recovery tools that can help fix problems starting windows. Select an operating system to repair. If your operating system isn't listed, click Load Drivers and then install drivers for your hard disks", select the "Windows 7 Enterprise (recovered)" OS and clicked "Next".
   
   
4. At the "System Recovery Options" dialog box, I clicked "Startup Repair" -> "Automatically repair". After a while, I restarted the computer to complete the repairs by clicking the "Finish" button. The Dell Optiplex GX620 pc boot up Windows 7 Enterprise OS normally without showing the "BOOTMGR is missing" error.

Using shsurdrv.exe to create a ramdrive in MSDOS on pc with memory greater than 2 GB (Rev: 1.1)

I created a MSDOS boot CDROM disc to run ghost.exe so that I can backup or restore computer. I used WinZip to compress ghost.exe as ghost.zip in order to reduce the ghost file size. Then, I used xmsdsk.exe v1.9I (a ramdrive application) to create a ramdrive in MSDOS so that I can unzip the ghost.zip to the ramdrive as shown below in the autoexec.bat (no need to configure xmsdsk.exe in the config.sys):

autoexec.bat
---------------
set ramdrv=r:
rem To create a 16 MB ramdrive at r drive
rem on top of the XMS memory (/t)
xmsdsk.exe 16384 %ramdrv% /y /t
if exist ghost.zip pkunzip.exe -e ghost.zip %ramdrv%


However, xmsdsk.exe does not function correctly on computer with memory greater than 2 GB because it will produce a "XMS get free mem error". On computer with less than or equal to 2 GB of RAM, xmsdsk.exe runs OK without the "XMS get free mem error". Removing the /t parameter (top of the XMS memory) in xmsdsk.exe also has the same "XMS get free mem error".


Hence, I removed xmsdsk.exe and try using another ramdrive application, shsurdrv.exe v1.11 in MSDOS. I added shsurdrv.exe in the config.sys (no need to add shsurdrv.exe in the autoexec.bat) as shown below:

config.sys
------------
files=40
buffers=30
lastdrive=z
dos=high,umb
device=himem.sys
device=emm386.exe
rem Create a 16 MB ramdrive quietly at r drive
install=shsurdrv.exe 16384K,R: /Q
SHELL=COMMAND.COM /E:4096 /P

However, I encountered the "too big for memory" error when running shsurdrv.exe in MSDOS on a Dell Optiplex 755 or Optiplex 960 computer with 4 GB memory. On computers (eg: Dell Optiplex GX620 with 1 GB RAM or Dell Optiplex GX270 with 2 GB) with less than or equal to 2 GB of RAM, shsurdrv.exe runs OK without showing the "too big for memory" error.

I commented out the running of "device=emm386.exe" in the config.sys and the "too big for memory" error when running shsurdrv.exe in MSDOS on a Dell Optiplex 755 or Optiplex 960 computer with 4 GB memory did not appeared. I have no problem running ghost.exe in the ramdrive (r: drive), except that it is a bit slow (about 4 to 5 seconds) waiting for the ghost program to start.

Hence, you should add shsurdrv.exe in the config.sys and deleted the "device=emm386.exe" as shown below:

config.sys
------------
files=40
buffers=30
lastdrive=z
dos=high,umb
device=himem.sys
rem Create a 16 MB ramdrive quietly at r drive
install=shsurdrv.exe 16384K,R: /Q
SHELL=COMMAND.COM /E:4096 /P

autoexec.bat
----------------
set ramdrv=r:
if exist ghost.zip pkunzip.exe -e ghost.zip %ramdrv%
