I had 2 hdds, hard disk 0 size 1GB partitioned as C: with Windows 7 Pro 64-bit and D: data storage, together with a second hdd disk 1 partitioned with PCLinuxOS at the first 200GB and the rest (E: 1200Gb) again for storage/backup etc. Booting into Windows or Linux was handled by GRUB 2 in the MBR of disk 0. I decided to remove the Linux partitions on disk 1 and extend the other partition (E to cover the whole disc. I used Update MBR from within HDM 15 to remove GRUB and the pc then booted straight into Windows. I then tried to extend the NTFS partition on E: to cover the whole disk. I deleted the 3 Linux partitions, leaving the first 200 GB of the disk as unallocated. I then right clicked on the NTFS partition and selected Move/Resize Partition. I dragged the left side of the partition to cover the unallocated space, so that the partition covered the whole disk. I then selected Apply. The Progress dialog showed Overall Progress 0% (Move Partition) in the header, and Move partition Still preparing, please don't lose hope. I then received a dialog stating System restart is required to complete the operation. What would you like to do ? Restart the computer Retry. I selected Restart, the pc restarted and displayed the Paragon screen. This said that the operation was proceeding, and then I received a message Some Error Occurred: Bad parameter of function. The pc then locked and I had to switch off power. Restarting brought me into Windows. I tried again, and this time the progress dialog stated that all operations had been carried out, but still received the Restart message. After restart I received a message Some Error Occurred: Cannot lock target partition. Again the pc locked up. Restarting again brought me into Windows, but HDM showed that no changes had been made. I would not have thought that a restart would be needed for the E: drive, since this is not the system drive. Could it be that this drive is still set as bootable ? If so, how can I remove this attribute ? Any advice gratefully received.
