Windows 7: boot manager

29 Dec 2009   #11

We help fix/remove these dual boots here every day.

When Win7 is correctly installed last it is not marked active because it puts boot critical files on the XP partition which remains System Active.

However, unexpected partitioning issues can derail the correct Dual boot.

This is normally immediately evident by looking at the full Disk Management map, as well the listings from the front panel of EasyBCD, the tool ultimately used to reset the Dual Boot menu

Needed corrections are first made to partitioning using free Partition Wizard CD, which works best in Win7 and has helped successfully remove and correct more than a hundred dual boots here since Win7 release.

The steps to get Win7 running so that we can view the screenshots requested are in my post above.

As was mentioned if you had just installed Win 7 after XP was installed and booting, the boot menu would have been created for you. If it did not work that way, then you are past making windows behave as it should.

Do you have 2 hard drives? The installer looks for the first active partition on Disk 0. We just had someone that had the boot information put on a data drive which was drive 0, that had an active partition, instead of the system drive. So his boot files were on a data drive and both his system partitions were on another drive.

This is not good.
I followed the steps
Windows 7 boots again.
The menu is there.
But XP wouln't load. It says it can't find \ntldr
And also, when the boot menu came up it wouldn't let me select the Windows 7 OS.
As it was before, but in reverse.
And since I couldn't get into XP either I was stuck
I've runs the repair three times again.
It seems to think it's repaired 7 but I still get stuck at that boot menu.
So I went back to the partition wizard.
And made XP the active partition again.
And it now boots to XP again.
I really want to run in Win 7
I do need to keep XP, because of one annoying piece of hardware we have, that won't work under 7's drivers even in compatibility mode.
Otherwise, with my data safely on the XP partition I'd happily just reinstall 7 and stick with it.

You may want to download the 2.0 version of EasyBCD, it seems to work better in Win 7.

Did you, or did EasyBCE move the ntldr, ntdetect, and boot.ini files into the boot directory, which is probably the Win 7 partition?

Edit that boot.ini and see if it mentions the partition value for XP as 2 instead of 1. EasyBCD can do this under tools, legacy.

The newer version of EasyBCD might also change the drive letter for XP to F: instead of C:, so if all else fails you might try that. Or, it may be a combination of the boot.ini and the boot menu entry, still a little uncertain about that.

You might try these items one at a time to see if it will boot.

You never posted back screenshots for Disk Management or EasyBCD so we weren't able to advise you the correct steps before you messed up your system.

What is the SpareOne HD which is marked active in the screenshot posted above, and why?

Use Partition Wizard to rightclick Modify>Set Inactive all other drives, then Rightclick Modify>Set active Win7.

If Win7 will not start, boot into Win7 DVD repair console and run Startup Repair 3 separate times. In Win 7, run EasyBCD correct version to add the 3 files needed (below)

You need to use newer version EasyBCD 2.0 linked in my earlier post to avoid the F: letter problem. Attachment 44601

"ntldr is missing" can be fixed. EasyBCD 2.0 will do this for you when you Add XP.

To make sure the 3 files boot.ini, ntldr, and ntdetect.com are in the roots of both OS drives:

Go Control Panel>Folder Options, on View tab select "Show Hidden Files" and uncheck "Hide Protected operating system files". Apply and leave open.

Look in the root of both drives for these three files. If any of the three are missing in either OS root of drive C or F then copy the file(s) until all 3 appear in the root of both XP and Windows 7.

Now change settings back in Folder Options, restart.

The spareone is, quite literally, a spare USB thumb drive that I used to install easybcd from.
It's probably "active" because I also have a live linux loader on it.
I'll try the things you advise as soon as I can. Which will maybe be on December 31st if possible.
But since this is my daughter's PC ( which is why it has XP and one major reason why I'm dual booting - she'd murder me if I lost her Sims3 files - though I have backed them to a portable HD) I'm limited as to when I can get to it.

If the worst came to the worst I can do a straight reinstall of Win 7 - since all the data files are on the XP partition, not the Win 7 partition. But my wife also uses this machine for one small "legacy" device that needs XP drivers. So I'm really grateful for your help.

When you run Win7 Startup Repair it only recovers Win7. It does nothing to fix the Dual Boot, and in fact usually removes it in favor of Win7.

You essentially cut XP out of the Dual boot doing this, but the fact you were then able to mark XP active and boot into it alone means that both are working and only need to be added back together in a Dual Boot using EasyBCD 2.0.

I am not sure you can run version 2.0 of Easy from XP. One could run older version (with F: drive glitch here) if you install Net Framework 2.0. Worth trying that to install 2.0 in XP to Add Win7.

Otherwise you need to Startup Repair Win7 until it starts, and use EasyBCD 2.0 in 7 to Add XP. It will prompt you to add 3 files, accept and it will autocomplete.

Win7 also might start if you move active flag back using PW as you did to XP.

I'll have a go at this. I know that /ntldr seems missing in XP when Win 7 is active.
So If I make Win 7 the active partition with the partition wizard s/w and then boot into it and copy each of those files into XP, starting with ntldr, maybe XP will boot, then.
I'll look at the boot.ini file too.
I'll get back to you when I've been able to do this.

Thanks for the help.

OK.
Happy new year.
Story so far...
Machine is booting into XP fine, with 7 not appearing.
Which is fine, for the while.
I looked for boot.ini on the XP partition and didn't see it.
I ran msconfig and looked at the boot.ini tab.
It has the XP boot options (XP and recovery consol) and the hardrive details with a (2) next to the XP partition.
I haven't changed anything. OR run EasyBCD yet.

This is the boot.ini entry, which is found on the C: drive as is the ntldr and ntdetect
