Windows 7: (Another) 0xC000025 error

You must have selected to convert to Dynamic in order to create the fourth partition for Linux.

You'll need to convert the HD back to Basic: Convert a Dynamic Disk to a Basic Disk

If you can find version 4.2 of free Partition Wizard, it still has conversion included in the free version and is the only non-destructive way to convert. Back up your data anyway if you can access it: Copy & Paste - in Windows Recovery Console

If Win7 won't start after conversion, make sure it is marked Active using Partition Wizard CD, then run Startup Repair from the DVD/Repair CD repeatedly with reboots to try to start it.

Windows 7 Professional

OK, re converting the disk from dynamic to basic, I have "paid" for the Professional edition of Partition Wizard. Upon clicking on "Bootable CD" in the professional edition, I get redirected to a page which simply tells me how to download the free one. I downloaded that (located here: Free Download Magic Partition Manager Software - Partition Wizard Online) and when I try to use it the dynamic to basic conversion is grayed out.

Am I missing something?

I just tested this in VirtualBox and it will convert a Dynamic disk to Basic with the Partition Wizard 4.2 installed to Windows 7 and it requires a system reboot to complete the process.

I don't know how to go about it if you can't boot to Windows to start with.

See the link in THIS post.

I would email Partition Wizard support to ask how to get the feature you paid for supplied on bootable disk.

Otherwise I'd move the HD to another computer, install PW 4.2 then do the conversion based on BFK's test which worked from Windows.

So it appears as if there is nothing I can do? By the way, by making the 3rd partition "Active" I now no longer have the "No bootable disk" problem at startup, but windows still has a BSOD.
