Windows 7: Can't delete one of the files belonging to the old OS.

Posting back the screenshot would still be a good idea as we see something awry in more than half of the thousands of them that we see.

Microsoft Windows 7 Ultimate 64-bit 7601 Multiprocessor Free Service Pack 1

No problem, thanks for your interest. When I later added my 2x1TB HDD's (one of which had been split in three partitions, one with the old Windows files on it) I found myself with 'Drive D: System Reserved' which Google told me was related to BitLocker. I used Disk Management to delete that drive letter.

You can Extend C in Disk Mgmt to take up the 11gb Unallocated Space.

At the minimum mark the old drive's System Reserved Inactive, only the partition booting Win7 should be marked Active: Partition - Mark as Inactive - Windows 7 Forums . Then I would delete it, move the 13gb files off of G and delete it too, then create a new G in the space. This is how to delete an old OS correctly.

If the drive ever interferes, move all data off and wipe it with Diskpart Clean Command which clears the boot sector of remainder code.

Thanks again, I've extended C as suggested.
As regards the 100MB of Disk 1 with no drive letter, is it not easier to just delete it and skip the 'mark as inactive' step?

It may not delete in Disk Mgmt if Active.
