Windows 7: Trouble in Partition

I have two partition done for my dimension 9200 and installed windows 7 and windows xp This was done few months back but now, I cannot access one of the partition. Can I format it in any way so that I can utilise that .?

Which partition can you not access and why?
If it is the primary partition and you are dual booting then you will lose the other partition, if it is the other way around then go for it.

Hi Josh -

Can you post back a screenshot of your maximized Disk Management drive map using Snipping Tool in the Windows 7 Start Menu, or if it's from XP use this: Screenshot with Paint

Tell us what's on each partition, which one isn't working and which you want to remove. We will give you the steps to do this, including recovering the disk space into the remaining OS partition if you wish.

Maybe yous Os crashed on that partition.You can format and install new os on that partition again and use it if its a normal problem.
Anyway more clarification and details needed for further help

Hai Gregrocker, I am sending the maximised snapshot of disk management page. I cannot access the drive Achu D:.

I'd move the System boot files to Windows 7 partition which works better, but first you must convert it to a Primary partition so that it can be marked Active and receive it's own boot files, because Windows 7 was installed to a Logical partition which cannot be marked Active.

To do this, boot into free Partition Wizard bootable CD, rightclick on C, select Modify>Convert to Primary, click OK, then Apply.

Once it completes and is now a Primary partition, rightclick on C to Modify>set to Active, OK. Then I'd delete the small empty partition to it's right so you can Resize Windows 7 into that space. Apply all steps.

Now click on the Disk # to highlight it, from Disk tab select Rebuild MBR, Apply. Reboot to see if Windows 7 will start. If not boot into System Recovery Options on Windows 7 DVD or System Repair Disk to run Startup Repair - Run 3 Separate Times until Windows 7 starts on its own and is labeled System Active.

Now you can install EasyBCD 2.02 to Windows 7 to Add XP, Save and reboot to see if it will boot from new Dual Boot menu. If not you may need to run XP Repair Install or reinstall XP.

Thanks a lot Greg. For this do I have to download and make a partition wizard bootable CD ? Do I need to back up my files before booting up ? Actually, I do not need to install another operating system, but want to use the partition as a storage. The small partition (Q: is also not accessible. Will there be any problem if I remove that partition ? How can I remove that partition if it is not accessible ?

I don't see a Q partition in your picture. Which partition are you referring to?

I would leave the small 63 MB OEM partition alone.

What about the 4.64 GB partition..did you make that partition or was it there when you bought the PC? If you did not make it, I would leave it alone.

You should always have your data backed up any time you begin fiddling with partitions. Things can and do go wrong from time to time.

I think the bootable Partition Wizard is likely to be less problematic. If all you want to do is delete Achu D, that should be easily done.

I did not make the small partition Q, 4.64 gb, neither it came with the system. I will leave it alone. If I delete the partition Achu D, will it be merged with C: automatically ? or will it stay as a free space ?

If you delete Achu D, it will become "unallocated space".

You can then use Partition Wizard to add that unallocated space to C.

I'd investigate the 4.64 GB partition. You say it did not come with the system and that you did not create it. Who did create it? Normally, I'd think it was a recovery partition of some type that the manufacturer put there---in which case I would leave it alone. But you say it was not on your PC when you bought it, so who knows what it is.
