Windows 7 not booting after mistaken converting partitions to dynamic

[chopadepravin9]

I have windows 7 32 bit PC, while creating new partition from unallocated space I mistakenly converted all partitions into dynamic. And when I restarted my PC it shows manufacturer logo and then black screen with continuously blinking cursor.
I'm unable to access anything.
And I'm afraid of data loss.
How I will recover my system without any data loss.
Please help me

Did you create a System Repair disc? If so can you boot to it? If not I'd download a Linux LiveCD or LiveDVD .iso file to a computer and use a CD/DVD burning program to create the disc then boot to it to save your data files, anything you created or that exists nowhere else. Plug in a USB Thumb/Flash drive or USB HDD/Hard Disk Drive before booting Linux and copy to it.

The problem is that you converted your HD to Dynamic which is only meant to be used to span a partition across multiple HD's. Apparently you didn't see the warning message that you were about to exceed 4 Primary partitions.

The solution to solve this non-destructively is to boot free Partition Wizard CD version 4.2 from Option One of Convert a Dynamic Disk to a Basic Disk

Download the ISO, rightclick to burn it to CD using Windows Image Burner, or use ImgBurn.

Boot CD. You will need to delete the extra partition(s) you created which tipped it to convert to Dynamic before it will convert back to Basic, so back up any files first from within Windows 7 if it will boot, or Copy & Paste - in Windows Recovery Console

Then follow these video steps: How to convert dynamic disk to basic disk with Partition Wizard?

If Windows 7 will not start and you confirm it's been converted successfully, then confirm that the 100mb System Reserved partition (preferred if you have it) or C is Set Active partition - Partition Wizard Video Help, then run Startup Repair - Run up to 3 Separate Times.

After conversion if you want help adding a partition post back a screenshot of your maximized Disk Mgmt drive map with listings, using the Snipping Tool in Start Menu, attached using paper clip in Reply Box.
