Windows 7: Converted disk to dynamic by accident... :(

Converted disk to dynamic by accident... :(

Hello,
I have 2 operating systems installed on my computer: Windows 7 and Ubuntu 9.10
When I was trying to create a new partition, I accidentally converted the main disk into a dynamic one and now it doesn't want to boot: it crashed at the GRUB and restarts the computer automatically.
I tried to revert back the partition codes from 0x42 to 0x07 for NTFS and 0x83 for linux but GRUB still crashes.
I don't really care that much about the linux partition, but I want to recuperate my main windows partition. I tried the Windows Repair from the CD but it doesn't detect any problems.
I don't really feel like backing up the whole system, formating the disks and all cuz I don't even have a spare HD for that.
Is there any other way around the problem?
Right now I only have access to ubuntu 9.10 in livecd mode.
Thank you

Nevermind, got it fixed.
After having changed back my windows boot partition and main data partition to ntfs, I've reinstalled ubuntu and it has rewritten the GRUB. seems like everything works now

P.S. stay away from windows Disk Management tool

That is good news, well done.

Windows Disk Management tool is very good for Windows.

I'm hoping this part was meant in jest. The Disk Management tool is great for most operations, and works quite well. I honestly have no idea how you accidently converted to a dynamic disk, including accepting the warning and prompts, when you were trying to create a new partition. Those are two separate options, and each have their own separate set up of sub-options and warning prompts.

Anyway, I'm glad you get it fixed and got your data back. Chalk this up to one more reason to use a VM rather than a multi-boot system, especially if you don't like to mess with partitions.
