Dual Boot: Cannot "see" data partition

Dual Boot WP/Win7.
My pictures are located on P:\ on separate HD, I can view the partition in Disk Management, but it will not let me set drive letter.

IF i attempt to make "active", i get a warning about "...if contains operating system...." etc..

Here is screenshot of when i attempt to add drive letter:, and a screenshot of warning when i attempt to make "active"

Yes, its true. It is not to activate a partition that doednt contain os. In this case your computer will stop working (bcoz that partition doesnt have any boot image).

Look for the "system reserved" partition (about 100 mb). If it is activated, there is no problem at all. The partitions containing os should have boot flag. In this situation, I think you will be able to operate all the partitions in explorer in either os, if there is not a ownership problem.

I think it is wise to have a third party disk manager (like acronis or paragon) to have a good dual boot system, and a bcd editor like vista boot pro or easybcd.

Please post the full Disk Management screenshot so we can see it to advise you better.

As Arc warns, do not mark the data drive active. XP needs to remain System Active with WIn7 holding boot.

The partition in disc 0 (19.53 GB) and another in disc 1 (9.77 Gb) seems to be not formatted. Are you sure they contain any data? If so, a software "Recover My Files"
(Data Recovery Software to Undelete Files; Disk recovery; Recover Deleted Files) may help you. But if it a free partition, Then format those partitions (first delete, then format). In my opinion, the partitions other than system better to be logical drives, not primary partitions (with a deep sky blue color, not navy blue).

In addition to the two unformatted partitions, your System Active drive has been derailed to G partition on DISK0. This means that critical boot files have been placed there because it was somehow marked Active, and as the first Active drive Win7 placed the MBR there.

As Arc says, data partitions should be formatted logical since they cannot be marked active.

You need to attempt to recover your pictures, then consider if you would like to move data off of G in order to format all of DISK0, recover the MBR into Win7, then reconfigure the Dual Boot correctly.

It will run the way it is now but is not correct because DISK1 is dependent upon DISK0 to boot. Let us know if you want to fix it and we will give you the exact steps.

Why do you think your data is on space? Could you be confused about where you put the files?

It looks a little strange, since it does not say unallocated, it does to seem to be a partition, but a partition normally gives its condition.

Could some utility have set the partition up just for you music and you might need that utility to access it?

You say it will not let you add a drive letter? Have you tried a command line utility to add a letter? Could it be formatted with something Win 7 doesn't recognize?

There are several different typed of partitons, so this might be something I haven't seen.

Yes I need to get it right, how about if i disengage drive 0, and boot back up on the drive with the dual boot os's?
Then start from there?

If not, please tell me the steps....I don't really know why i want to hang onto the Dual Boot, but feel confident that i have a 32 bit system in case i have an app that won't load on the jWin7 64 bit..

It doesn't hurt to try. It might be that XP will boot if Drive 0 goes away, but hard to tell.

If it won't boot, then all your boot files are on the current drive 0.

If you have to reinstall it to boot, make sure you set it first in the drive order in the bios.

There may be some files on the Drive 0 you may need later. If you can, copy them to an external drive, or the root of Drive 1. They are, the bootmgr file, and the Boot folder.

Drive 1 view only

Ok, i disconnected my Data Drive that contains the Data and Pictures. Here is the Disk Management view now of the Dual Boot drive.

Do i just do a reinstall of Win7 now?
