I did this and it removed the annoying boot menu when booting to my XP drive (C which was great, however now I can't boot to my Win7 drive (F. It says the NTLDR is missing.

I was simply trying to remove it from the boot process when I boot up my main XP hard drive, as whenever I would boot from my C drive, I would get the option to choose Windows 7 (which was no longer there from a previous install). I then reinstalled Windows 7 on my F: drive (completely independent of C and now it no longer boots. Is there a way to fix this?

You are not the original poster here so I do not have the background of your case.

If you reinstalled Win7 it should have reconfigured the dual boot menu correctly. Something must have blocked it.

Boot into the Win7 DVD repair console and run Startup repair repeatedly to get Win7 started.

Post back a screenshot of the EasyBCD listings so we can what needs to be adjusted. If XP is missing after Win7 Startup repair, add it by name, type and correct drive letter.

I reinstalled Windows 7 onto a separate drive with only that one connected so as to help prevent it from installing onto other drives. So, the dual boot menu on my C: drive still lingered for a while (with nothing associated with it after dual booting from that drive to Win7 but then blowing Win7 away after deciding to go for a separate dedicated drive for it).

See if you can boot into Win7 by setting it as the HD to boot first in BIOS setup after DVD drive.

Then if you need to boot into XP, you can use the BIOS Boot Menu shortcut F-key given on first bootup screen.

This is actually better because it makes the HD's independent of one another and can come and go as you wish.

If you still want to create a Dual Boot menu then you will need to boot into Win7 with XP plugged in and run a Repair Install to correctly reconfigure a dual boot.

That is actually how I have it set up. Both drives are (were) configured to boot independently. At startup, I hit F8 to choose which HDD to boot from. However, after booting into XP and using the Vista bootloader uninstaller, when I tried to boot back into the Win7 HDD via F8, it says it was now missing the NTLDR. I wasn't aware that uninstalling it on my XP/Win7 Drive would remove it from my new dedicated Win7 drive as well.

When you use EasyBCD to uninstall Vista bootloader it finds that bootloader and uninstalls it, which is why you can't boot Win7. If you were trying to delete the ghost listing given at XP startup, it needed to be done in msconfig>boot tab or EasyBCD Add/Remove listing.

Have you booted into the Win7 DVD repair console and run Startup Repair 3 separate times to attempt repair and then rewrite the MBR to Win7? Unplug the XP drive first.

Can you boot into an OS now? Which?

Please boot into that OS and post back a screenshot of the EasyBCD listings AND the full Disk Management drive map. https://www.sevenforums.com/tutorials...en-forums.html

I'm gonna try the Windows 7 Repair Disc tonight with all other drives unplugged. Then, hopefully that fixes the Win7 drive. Then, I'll disconnect the Win 7 drive, boot into XP, and run the Vista bootloader uninstaller again to get rid of it (because it's back now for some reason - i think i was playing with stuff and added it back). Anyway, I'll report back regardless of what happens after this.

Remember to run Startup Repair 3 separate times to get Win7 restarted as it assumes each fix will work until you come back for another, until it finally rewrites the MBR. Many ignore this and then wonder why their computer won't start.

The Vista bootloader is not responsible for the ghost listing at XP boot. As stated earlier, it is removed in XP msconfig>Boot tab, or by removing the listing (not the bootloader) on EasyBCD's Add/Remove tab.

Hi,

You just need to boot into 7, install Easybcd, click Useful Utilities>Easybcd Power Console.

An elevated command will open at easybcd bin folder, type:

bootsect /nt60 c:

then press enter.
