System Improperly shut down, UNMOUNTABLE_DISK_VOLUME BSOD

Without an active partition.. it doesn't know where to boot from. Because bootmgr is not on disk you see the error message.

Make PQSERVICE active instead of ACER. Now try to boot normally. Works? If not...same error? Does it boot win7, or do you see ACER recovery menu?

From what I discovered. PQService Partition gives out an message saying Error! when booting, and the strange thing is the SYSTEM RESERVED partition gives out the "UNMOUNTABLE_BOOT_VOLUME" BSOD error after staring windows 7. So, the system has been booting from the SYSTEM RESERVED, where the error started.

Did you check on which partition file /bootmgr is? Most likely only "system reserved" has it. Please confirm

An unmountable boot volume error means that the operating system cannot boot from the hard drive either because the boot files are corrupted, the hard drive is faulty or there is a problem with the cable connecting the hard drive to the computer.

hard drive faulty.....: Can you explore ACER partition and see files?
cable problem: Very unlikely... you see partitions.

Make "system reserved" active. In win7 recovery environment->command prompt:

Code:

bcdedit

What do you see? Make camshot and post

So... diskpart
sel disk ... lists only 1 only 1 disk

sel dis 0
list part

doesn't show any partitions ...correct?

But partition wizard shows them... very strange


Even boot from "system reserved" does work... although it crashes when trying to mount C
It has run bootmgr.. so it's readable and there are files. Can you see a lot of files in partition wizard->explore partition on your ACER drive and system reserved?

You have 4 partitions in total....isn't it?
system reserved. Real win7.... and 2 for recovery. Correct?

Strange PW sees everyting. Win7 boot process partitially sees partitions. It sees system erserved boot sector and bootmgr. And most likely bootmenu.

In PW do a resize of ACER and "system reserved". First make "system reserved" ACTIVE if not already yet.
Make C somewhat smaller by dragging left (not the right) handle. So make some unused space on left. (For exmaple 1GB smaller)
Also make start point of "system reserved" different. Drag whole partition to the right so it gets another start point.
Then apply changes.

So change the start position of partition....

Do you have an external disk with a lot of free space?
