Partition Editing, Booting problems

Specs: Windows 7
One of the most painful system reinstallations I've done so far.

My goal was to have Windows 7 and Windows XP installed, so that I could choose between them (I actually had it set up like that before formatting, for whatever reason I ran into lots of problems this time).

So here's what I've done (skipping the irrelevant parts):

1. I had 465 disk divided into 3 partitions:
- Q: 100MB System Reserved (hidden, Windows 7 automatically created partition)
- C: 50GB Seven (the partition where i keep windows Seven)
- D: 200GB Data
- E: 125GB Games
- 90GB Unallocated space

2. I burned and used GParted to rearrange my disk. I've done that successfully (extended Data to 250) but here are first two doubts:
- The pre-installation screen of GPartedLive was covered in green pixels (the background is normally grey. What can cause that?
- While installing I was flooded with errors like this:
end_request: I/O error dev sr0, sector 240736
Buffer I/O error on device sr0, logical block 60184

Yet it ended up working.

3. After using GParted and then installing Windows XP my disk looked like that:
- Q: 100MB System Reserved (Windows 7 automatically created partition)
- C: 50GB Seven (the partition where i keep windows Seven)
- D: 250GB Data
- 125GB Games
- H: 25GB Windows XP
- 15GB Unallocated Space
Windows XP was working normally.

4. I decided to reinstall Windows 7 so I used GParted again and here's where real problems started.
I removed the 100MB+50GB Partitions, creating a new 50GB one. GParted done it but also, all of a sudden, created an Extended partition out of Games, Windows XP, and a part of Unallocated Space. It also rearranged the letters. It made it impossible to use Windows XP as it became logical partition. I don't know how to revert that change.
It's also weird that the 50GB partition was created but there was 16MB left between it and the Data Partition. I had to remove and recreate it.

5. I was forced to install Windows 7 so I did it. As it had partition already prepared it didn't prompt me to create this 100MB partition (the one with a couple of bootable files).

6. Using EasyBCD I wanted to somehow revive the Windows XP but I couldn't create Bootmanager there as it was logical partition. I accidentally created Bootmanager in Data Partition. Windows 7 didn't boot the next time, obviously.

7. I reinstalled Windows 7 and again wasn't prompted for creating the 100MB since it apparently used Bootmanager located on Data D:\ partition.

8. I recreated Bootmanager on C: and it became System, Boot partition once again (with this tutorial). Both Bootloader and Bootmanager are on C: now.

9. I can freely remove Bootmgr and Boot folder from C: but I can't from D: (it was created with EasyBCD2.02). Windows 7 prompts me that "You require permission from TrustedInstaller to make changes to this file". How can I remove those files so that the next time I install Windows 7 it won't use them?
I managed to change ownership and rights but it only affects one file so it's painful process.
Why are those files created by EasyBCD protected like that anyway? :|

10. Side question. After installing .NET Framework 4.0 I couldn't run any application that uses .NET (including EasyBCD and ATI Catalyst). Why is that? I had to install .NET 3.0 (all of that concerns only Windows XP, obviously)

Your post is lengthy and difficult to follow. That said, I believe your problem stems from the fact that you can't have more than 4 primary partitions or 3 primary partitions and 1 extended partition with as many logical drives as there are available drive letters.

Additionally, the 100MB partition you combined with other space was most likely not contiguous with the 50GB. This in itself would be a problem.

Net frameworks versions are NOT interchangeable. If a program needs a certain version, that version must be installed. You could conceivably need all versions.

You have such a convoluted mess that I suggest you just start over. If that is not possible then try undoing the partitioning changes.

Also, the 100MB partition created by WinXP is there for a reason so I suggest you leave it alone.

i would suggest that begin again, install xp 1st, then install win 7 using the win7 installation go too advanced and create all your new partitions but leaving the xp partition and installation as is,
once the win7 installation completes you will have both xp and 7 as boot options, win 7 will boot as the C drive, no matter what position it is on the dvive.
you will not require G-parted at all, you can create all the partitions you need after installing xp, using the win7 dvd.

i hate computers!
but cant help myself....
