Windows 7: No boot without installation disk

No boot without installation disk

I just installed Windows 7 64 bit Home Premium yesterday from iso burned onto a disk. I have been running XP 32 Home edition for years. I installed Windows 7 on a different partition on the same disk as XP. If I restarted the computer without the Windows 7 install disk in the drive, XP would boot up and I would not get a menu to choose between XP and Windows 7 like I did back when I was running the Windows 7 beta early in the year. When I put the install disk in, it will go straight to Windows 7 without a menu to choose from as well. I then went into disk management in Windows 7 and chose the Windows 7 partition as the active disk. It listed the partition as boot, so I assumed it was good to go. I then restarted the computer without the install disk in, but I get the NTLDR missing, press ctrl+alt+del message. So I figured the boot files on the Windows 7 partition weren't there or were corrupt, so I booted from the Windows 7 installation disk and used the repair utility. It detected nothing to repair, so now I am stuck. Any ideas as to what I am doing wrong? Shouldn't the repair utility on the installation disk detect a missing or corrupt boot file? Or is it seeing the boot file on the XP partition and I need to delete or rename it to keep the repair tool from seeing it?

edit: I just did a search for boot.ini on my computer and it is indeed in the XP partition, but no boot.ini file on my Windows 7 partition. What is the best way to deal with this?

Alright, so I tried renaming the boot.ini file on my XP partition to boot.backup.ini, hoping it would force my system to ignore it, and ran the repair utility again from the Windows 7 installation disk. Same thing, the utility said it didn't find anything wrong and there is still no boot.ini file on my Windows 7 partition. I'd rather let windows make the boot.ini instead of writing one, because I am not entirely sure what I'm doing. Is there a solution out there to this problem?

Hi,

Boot is the partition you are currently booted into. System is the partition containing the boot critical files. 7 won't make a boot.ini on the root of the drive.

If you messed with the original XP boot.ini - put it back exactly the way it was.

I would assume the bios boot order has cdrom first, Disk0 second.

Try this:

From within 7 ( with the dvd in the drive) - as you are now, in fact.

In Disk Management, rt click the IDE partition and assign letter J.

Open an elevated command and type:

bcdboot c:\windows /s j:

then press enter

H:\boot\bootsect.exe /nt60 j: /force /mbr

then press enter.

Remove the dvd from the drive and restart.

Back in 7, open an elevated cmd and type ( press enter after each line):


bcdedit /create {ntldr} /d "Windows XP"

bcdedit /set {ntldr} device boot

bcdedit /set {ntldr} path \ntldr

bcdedit /displayorder {ntldr} /addlast


Then close cmd prompt.

Hope it helps

I had a sneaking suspicion you would look at that IDE drive, as I started wondering about it myself. I'll try all that and post here whether it works or not. Either way, I thank you for your help.

I ran into a problem right away. I can't copy the boot files from the IDE...it's not quite working for some reason (says failure to copy). I haven't used that drive in a long time now because it was acting up. It has my original XP on it. I had cloned that drive to the XP partition on that SATA drive. Apparently my machine has been booting from the IDE all this time? At any rate, if I click on the IDE in explorer it show 0 files, but looking at properties it shows full. So my question is, can't I just format the IDE (assuming it will let me)? I really don't care about the data on it any more. If I do this, in effect destroying the bootfiles, would the repair feature on the disc fix my problem?

Ok, never mind, I was reading another post, so I guess I cannot format the IDE because it is the "system". So could I simply disconnect it? I guess all I need to know is, if there are no boot files available, will the Windows 7 installation disk repair tool make them on my Windows 7 drive?

Yes it will make the 7 critical boot files. - did you chicken out of the commands above?

You still need to do the commands to add XP to bcd after you disconnected IDE drive and run startup repair from the 7 ( may take 3 runs).

You need to make sure that Disk1 is first in Bios boot order.

You will need to also make sure vthe 3 XP bootfiles are on the 7 partition.

They are hidden files - ntldr, ntdetect.com and boot.ini

No, I tried the first command and it wouldn't work.

Ok, so I can disconnect the IDE, then start the computer, fire up the BIOS, make sure the boot order is DVD, then Disk 1, then save/exit, reboot on the DVD disk, run the repair tool and reboot how many ever times it takes to get it to not detect anything, then take the DVD out, boot up normal, if Win 7 comes on, then go from here:

Then close cmd prompt.

Is that all correct?
