Windows 7: Dual Boot Installation with Windows 7 and XP

Windows 7 Ultimate x64
 
 

Well, i would go to the recovery console and do the following:

FIXMBR
FIXBOOT


Then exit out, it helped me like twice. I'm just afraid that it will only clear out all other OS'es from the boot manager.

Something i have learned from a few years of dualbooting any OS i can get in my hand: As long as you are only dual-booting with Windows, you should start out by installing the oldes OS first, because you will always get the bootmanager done as the last thing.

If you're using Linux you should just use GRUB, you can edit your GRUB options from within your OS, and you can do whatever you want to with it, compared to Windows, which locks off some options (Usually the ones i need to use)
But yeah, if you got so much trouble with the Windows bootloader, you can install a tiny tiny Linux on a tiny partition, so you get the bootloader from there.


Besides it takes some time to get used to having your disks/partitions called hda0 hda1 hda2 etc. I spent quite much time figuring which of these were my primary partition (After some time i realized that SCSI disks aren't called hda)

XP / 7
 
 
Tangled Web woven...

Hi,

I seem to have got myself stuck.

A few weeks ago I installed XP on a new PC.
I was aware that 7 was coming along, so I created 3 primary partitions, and one extended partition holding drives d:, e:, f: and so on.

I installed XP, which went on the first primary partition.

Today I installed 7, selecting the second primary partition for it.

Having removed the 'boot from dvd' option from bios, I found that XP loaded automatically, with no options.

I managed to find the boot.ini file, and tried to add a second entry to specify the Win7 partition.

>>
However, although it could load XP successfully, if I tried the Win7 option I got a 'corrupt ntoskrnl' message.
>>

I saw some advice saying that you could only successfully boot xp from 7, and not the other way around.

So, I went into Disk Management in XP, and made the second partition active. (Hoping the second primary partition would now become the c: drive, and Win7 could boot as default).

>>
However, now when I boot from harddrive I get 'Bootmgr not found' error.
>>

I have since run a repair option from the Win7 DVD as boot device.

However I am now stuck.
Current situation:

1)
I can only run Win7 by booting from DVD.
It asks me my password and runs ok

2)
I saw some comment about running repair installation 3 times for Win7, but I no longer see that option on booting from the DVD

3)
I managed to find DiskManagement in Win 7, so I could make the first primary partition active again - so I can get back to XP boot ok.

4)
I don't know if my understanding about primary partitions is out of date.
I thought an advantage of swapping primary partitions is that XP and Win7 do not see each other, and therefore cannot overwrite or corrupt each other. Whichever partition is active, that is the only c: drive in town...

However, I noticed when in disk management in 7, that Win7 was aware of the XP primary partition, and had for whatever reason given it a drive letter d: ?
I don't particularly want this to happen, so is there any way around it?


5)
Any suggestions gratefully accepted...
Reinstalling 7 would be no problem, as all I have loaded is a graphics driver.

thanks

I got my installation working now. Thanks to EasyBCD 2.0 BETA 64. It automatically does it all for you creating the boot.ini and such for your xp installations, which was my problem.

Hello bathsheba666, welcome to Seven Forums!



Here's what I would do ...

1) Install windows 7 on the first partition.

2) Install XP to the second partition.

3) Do a 'repair' on 7 with the 7 disk so you'll have both options at boot time.


Please post back to tell us how it turns out.

Hi Bare Foot Kid,

Thanks for the welcome and suggestion.

I am slightly hesitant to reinstall XP elsewhere, as I already have installed licenced software, and not sure (from ignorance) whether the built in validation checks will choke on the new arrangement when I reinstall and revalidate it.


However, it seems to me that before I rearrange partitions, I should make sure I understand them, and it seems I don't , or something has changed.

I used to think that - with primary partitions - only one could be active at any one time.
So an OS on one, could not possibly see an OS on the other.
Here that doesn't seem to be the case?

Am I supposed to have all partitions named and provided with a drive letter - in both OSs ?
Or am I confusing this with an ancient setup where the first partition consisted of nothing other than a boot option which decided which of the remaining two primaries became active, and therefore booted?

The partitions I have, I created on the disk as part of the XP installation.
could it be that 'partition' in Windows means something different from what I had in mind?



Lastly, going back to your suggestion, would it be possible to get a utility to copy my XP installation from the first to the second partition?
and therefore hang on to existing installations and existing licences?
I imagine this might partly depend on the answer above about enabling one partition and disabling the other...

And the impression I get from all that has gone before is that there is a single boot record for the whole set of drives on the first partition of the first hard disk? would that be correct?

You should have no problems re-activating your XP on another partition on the same machine; if you choose to go that way.

True, they can 'see' each other.

No, you can choose whether they 'see' each other by deleting the drive letter, i.e. for XP in 7 so 7 can't 'see' XP.

Yes, you could use something like Acronis or Paragon to make a clone that can be used to image the OS to be used later.

Installed as I suggest W 7 will take over the boot process.

Thats how I have mine, 7 negotiates the dual boot better I feel. I had Xp installed first, then installed 7 (the second time around, first time the other way around did not go so well) From installing 7 second, it took over the boot selection and works well. Easily adjust times etc from the 7 interface. My dual boot PC is my house favorite now!
