Windows 7: Dual Boot: Cannot "see" data partition

03 Jan 2010   #31

Did you run the diskpart commands given to set G inactive?

It still shows Active in screenshot.

It isn't important to convert to logical.


Can you now boot into either Win7 or XP through a correctly listed Dual Boot menu?

Must I use command line to convert to logical drive?

Seems like a mess? but am getting there ...

Here is screenshot of XP Disk Managment....
Your problem (in my openion) is due to the storage of dual boot information in disc 0 partition G. It is to be recovered.
Had I been in place of you, I would have done the following things:
1. Log on in xp
2. format the partition in disc 1 containing win 7
3. use easy bcd to delete the windows 7 bootoader
4. copy all files in disc 0 in disc 1, creating a partition out of the xp partition coz xp dont require so much place
5. Install xp in disc 0
6. install 7 in disc 1
In my machine I use a partition named "system reserved" (100mb) to contain all the boot informations (in pic). I seem this plase is taken by partition G in your machine
It may be a labourous process, but the easy and secure way to overcome this situation

Hi Arc. We see this situation where MBR is derailed to an active data drive all the time here.

The solution is to mark the data drive inactive, mark Win7 active and then recover the MBR into the Win7 partition by running Startup Repair 3 times.

In this case, he ran a Repair Install which correctly reconfigured the dual boot with System Active MBR on XP and boot in 7. I believe he says the dual boot is working.

If not, then the data partition needs to be marked inactive. I am not sure why it hasn't been done already since I've given him the commands twice now.

If there is a problem, then the backup is to move the data off of DISK0 and use Diskpart commands to clean or force delete the drive.

Why does the screenshot taken from Win7 after the Repair Install correctly show XP to be System Active and WIn7 to be Boot, but the screenshot taken shortly thereafter from XP show only the data drive to be marked Active?

Did you accidentally use the Diskpart commands given to mark XP inactive?

It may be necessary to not only mark the data drive Inactive, but also mark the XP drive active to be sure, since it is not marked active in the XP screenshot you posted even though it is in the Win7 screenshot.

Also after Repair Install you say you have a Dual boot menu and can boot into "the single drive" but then post screenshots taken from both Win7 and XP? This is very confusing, and then you disappear.

Then what may be the reason behind not accessing the data drive p when 7 is logged on? Is the partition is formatted in such a type that may be accessed by xp but not by 7? IS there such a format?

I can't say why he can only see P:Pictures in XP, but am only glad to hear that he has them back.

This is not a reason to reconfigure the dual boot now, though, since it appears it is working (isn't it?).

What I would do is move the pictures into the free space in XP drive, use WIn7 Disk Management to delete the P partition, create new and format it Logical, then move the pictures back through explorer.

If the G partition cannot be marked inactive, then I would move Music off of it into XP and WIn7 partitions, force delete and format it Logical as well, then move data back.

What do you think of that approach?

Nice! it should work. I think you mean to log on in xp first, move the items using xp, then log on in 7, use disc management and so on. isn' it? (coz they are not accessible in 7)

I think it is better to have a third party disk management program. I use Acronis. It helps me a lot to manage my disks. But the experts dont need it at all .

Right, move Pics within XP, then delete/create/format in Win7 which is more advanced.

I only recommend third party for what Disk Management can't do, because Disk Mgmt doesn't fail while 3rd party apps can sometimes.

The one we find that works the best with Win7 is free Partition WIzard bootable CD. People we help here like its graphical interface with slider buttons, full automation.
