Disk 0 Dynamic Unreadable, 500gb hdd but only give me 220gb

Specs: Windows XP, intel i3/2gb ddr3
First of all, the way i got this problem is clearly not the same as others.
I'll give story how I got this problem.

1) i have an Acer Aspire X3990 , 500gb hdd. It was came / preinstalled with Windows 7 64bit.

2) They were two partitions in the computer.

3) I wanted to try dualboot it with Ubuntu. Unfortunately, I messed up. I installed the ubuntu on Win7 partition :( ..

4) Because I overwritten the win7 partition with ubuntu, automatically i lost my Acer eRecovery management function., so i cannot use my recovery partition.

5) Because i desperately need Windows, so I have no other option but to borrow my friend's windows XP install disc.

6) And s--- happened again (i think im s---) , I installed the winXP on 2nd partition !! , and i think it erased my first partition (ubuntu partition) too, maybe.

7) Tho, i successfully have winXP running, i can only see 220gb in the winXP , but when i open disk management, i saw this !! screenshot http://i.imgur.com/YJtce.png

8) I don't want to do clean installing again, are there any way to fix this? so i can use my other hdd. :( help me.

I can't help you with the XP install as you are using an illegal copy.

Most Acers should boot into recovery mode if you press <alt>-F10 whilst booting; this assumes that you have not overwritten the recovery partition. If this doesn't work then you need to buy Windows 7 installation media from Acer and revert your computer to its original configuration. Given the mess that you have made of things so far I would advise you to find someone who knows what they are doing to restore your PC.

The illegal copy you are using is the copy of XP that you say you have installed.

As for why you need to buy recovery disks - you didn't create them when you had the chance to and you may have messed up your recovery partition (of course you may not; you don't say whether you have tried that option).

Feel free to ignore my advice (but think carefully about getting someone who knows what they are doing to repair your computer).

I think ijack makes a good point. That said, if you haven't overwritten the restore partition then try using it to BOTH restore to factory state and create the restore disks.

If you have already destroyed the restore partition you can contact Acer for a restore set of disks. Most likely there will be a charge of $25/50. You can legally use a compatible Acer restore disk to restore your computer. That restore disk must be the same version of Windows and closely match your system specs.

Your illegal action was installing WinXP, that didn't come installed on your computer.

One last point to make. We have no idea what your first sentence means. If you want to refer to another thread here at CN then you need to provide a link.

Did you even look in your manual? If you didn't totally bork the partitions, here's how Acer says to do a system recovery.

To start the recovery process:
1. Restart the system.
2. While the Acer logo is showing, press <Alt> + <F10> at the same time to
enter the recovery process.
3. Refer to the onscreen instructions to perform system recovery.

If that doesn't work, have a look at this:
