command is correct
bootsect /nt60 e: /force
Target volumes will be updated with BOOTMGR compatible bootcode.
E: (\\?\Volume{d2602ac3-ded6-11e0-a821-806e6f6e6963})
Forced dismount complete, open handles to this volume are now invalid.
Successfully updated NTFS filesystem bootcode.
Bootcode was successfully updated on all targeted volumes.
don't you get the last two lines??
the command puts the bootcode on the external. At least it should do that. Do you want to disconnect external? Then you can't do the command!
Why are you trying to install from external btw?
Connect the usb external temporary to another machine. Start that machine from win7 repair disk or win7 installation dvd. Or just tap F8 multiple times so you see bootmenu and can enter "recovery environment" (last option only possible if win7 is on that machine)
In recovery environment you enter command prompt and determine drive letter of partition with installation files (so now it's E but it can differ!) just do
DIR C:\
DIR D:\
etc and find the right partition
Then do this:
bootsect /nt60 Y: /force
bootsect /nt60 Y: /force /mbr
(replace Y with right drievletter)
so enter recovery environment and from there command prompt
System Recovery Options
Boot to the System Recovery Options screen, and select the Command Prompt option. (see screenshot below)
Now the boot commands succedeed succesfully? you used another computer and usb port. and even another bootsect.exe. Maybe this helps
I have finally found a way to make the external HDD to boot but nothing happens beside a black screen with a white bar blinking at the upper left corner. It definitely doesn't work. I will just buy an USB pen and install Win7 that way. Thank you all for your tips, I appreciate.
How did you get it to boot to black screen with only cursor?
Did you rewrite mbr and bootsector finally?
I thought you did change boot device order a long time ago!! Of course you have to tell bios to boot from usb drive
=================
rewrite mbr and bootsector and it will boot from usb. Is it a problem if usb externel is cleaned totally? You have the install ISO on C-drive as well I assume.
There are tools to make a usb external bootable by other tools. But they clean the drive first!
