totally confused.... I thought your drive does have no partitions at all?! F8 starts win7 recovery environment from harddisk.
Ok, let me clarify.

The drive did have partitions until MBR was corrupt. When I went to win7 recovery environment from the hard disk, opened command prompt, typed diskpart>list disk, The disk (disk 0) shows up, so I selected the disk and typed list partitions, the partitions do not show up or it says "There are no partitions that can be shown".
But now partitions are back again? How did you recover them?

Well, they are actually not showing up. They show up when using the Partition Magic but not when using the diskpart>list partition command.

Is it in special raid setup or needs special driver?

Anyway... partition magic sees the partitions. All of them?

Please post screenshot/camshot. If not possible... tell me
  • sizes of partitions
  • All NTFS?
  • which are primary, which are logical?
  • Which is active?

What is partition 1,2,4 ?

ACER C: has bootmgr on it? Is that partition active? Is that partition primary?

Partitions 1 and 2 are System Factory Image and Something called PQ Service.

ACER ( C: ) is supposed to be primary and active partition.

The C: is not part of the name BTW, it stands for the C: drive.

Press Ctrl+Alt+Del to restart.
so you made ACER (C) active(?) so it was inactive? What partition was ACTIVE before that?

I sure that C: is Active, but bootmgr is not there. I thought it was at C:\Windows\boot, but anyways it is not there.
